This document discusses Alexander Tokarev's presentation on Oracle In-Memory from his experience working on performance tuning and proof of concepts. He worked on a faceted search project that saw a 5x performance boost from implementing Oracle In-Memory technology. Key findings included that not all data needs to be loaded into memory and understanding Oracle In-Memory internals like compression settings and repopulation processes are important for optimizing performance.
The presentation describes how to design robust solution for tagging search, how to use tagging for faceted search. Various architecture and data patterns are considered. We discuss relational databases like Oracle, full text search servers like Apache Solr. We will see how Oracle 18c features permit to use embedded faceted search.
The majority of cloud-based DWH provides a wide range of migration tools from in-house DWH. However, I believe that cloud migration success is based not only on reducing infrastructure maintenance costs, but also on additional performance profit inherited from tailored data model.
I am going to prove that copying star or snowflake schemas as is will not lead to maximum performance boost in such DWH as Amazon Redshift and Google BigQuery. Moreover, this approach may cause additional cloud expenses.
We will discuss why data models should be different for each particular database, and how to get maximum performance from database peculiarities.
Most of performance tuning techniques for cloud-based DWH are about adding extra nodes to cluster, but it may lead to performance degradation in some cases, as well as extra costs burden. Sometimes, this approach allows to get maximum speed from current hardware configuration, may be even less expensive servers.
I will show some examples from production projects with extra performance using lower hardware, and edge cases like huge wide fact table with fully denormalized dimensions instead of classical star schema.
Hekaton is the original project name for In-Memory OLTP and just sounds cooler for a title name. Keeping up the tradition of deep technical “Inside” sessions at PASS, this half-day talk will take you behind the scenes and under the covers on how the In-Memory OLTP functionality works with SQL Server.
We will cover “everything Hekaton”, including how it is integrated with the SQL Server Engine Architecture. We will explore how data is stored in memory and on disk, how I/O works, how native complied procedures are built and executed. We will also look at how Hekaton integrates with the rest of the engine, including Backup, Restore, Recovery, High-Availability, Transaction Logging, and Troubleshooting.
Demos are a must for a half-day session like this and what would an inside session be if we didn’t bring out the Windows Debugger. As with previous “Inside…” talks I’ve presented at PASS, this session is level 500 and not for the faint of heart. So read through the docs on In-Memory OLTP and bring some extra pain reliever as we move fast and go deep.
This session will appear as two sessions in the program guide but is not a Part I and II. It is one complete session with a small break so you should plan to attend it all to get the maximum benefit.
SQL Server In-Memory OLTP: What Every SQL Professional Should KnowBob Ward
Perhaps you have heard the term “In-Memory” but not sure what it means. If you are a SQL Server Professional then you will want to know. Even if you are new to SQL Server, you will want to learn more about this topic. Come learn the basics of how In-Memory OLTP technology in SQL Server 2016 and Azure SQL Database can boost your OLTP application by 30X. We will compare how In-Memory OTLP works vs “normal” disk-based tables. We will discuss what is required to migrate your existing data into memory optimized tables or how to build a new set of data and applications to take advantage of this technology. This presentation will cover the fundamentals of what, how, and why this technology is something every SQL Server Professional should know

MongoDB World 2019: Finding the Right MongoDB Atlas Cluster Size: Does This I...MongoDB
How do you determine whether your MongoDB Atlas cluster is over provisioned, whether the new feature in your next application release will crush your cluster, or when to increase cluster size based upon planned usage growth? MongoDB Atlas provides over a hundred metrics enabling visibility into the inner workings of MongoDB performance, but how do apply all this information to make capacity planning decisions? This presentation will enable you to effectively analyze your MongoDB performance to optimize your MongoDB Atlas spend and ensure smooth application operation into the future.
Learn how to achieve scale with MongoDB. In this presentation, we cover three different ways to scale MongoDB, including optimization, vertical scaling, and horizontal scaling.
Lessons Learned Replatforming A Large Machine Learning Application To Apache ...Databricks
Morningstar’s Risk Model project is created by stitching together statistical and machine learning models to produce risk and performance metrics for millions of financial securities. Previously, we were running a single version of this application, but needed to expand it to allow for customizations based on client demand. With the goal of running hundreds of custom Risk Model runs at once at an output size of around 1TB of data each, we had a challenging technical problem on our hands! In this presentation, we’ll talk about the challenges we faced replatforming this application to Spark, how we solved them, and the benefits we saw.
Some things we’ll touch on include how we created customized models, the architecture of our machine learning application, how we maintain an audit trail of data transformations (for rigorous third party audits), and how we validate the input data our model takes in and output data our model produces. We want the attendees to walk away with some key ideas of what worked for us when productizing a large scale machine learning platform.
Some of the most common questions we hear from users relate to capacity planning and hardware choices. How many replicas do I need? Should I consider sharding right away? How much RAM will I need for my working set? SSD or HDD? No one likes spending a lot of cash on hardware and cloud bills can just be as painful. MongoDB is different from traditional RDBMSs in its resource management, so you need to be mindful when deciding on the cluster layout and hardware. In this talk we will review the factors that drive the capacity requirements: volume of queries, access patterns, indexing, working set size, among others. Attendees will gain additional insight as we go through a few real-world scenarios, as experienced with MongoDB Inc customers, and come up with their ideal cluster layout and hardware.
Has your app taken off? Are you thinking about scaling? MongoDB makes it easy to horizontally scale out with built-in automatic sharding, but did you know that sharding isn't the only way to achieve scale with MongoDB?
In this webinar, we'll review three different ways to achieve scale with MongoDB. We'll cover how you can optimize your application design and configure your storage to achieve scale, as well as the basics of horizontal scaling. You'll walk away with a thorough understanding of options to scale your MongoDB application.
Topics covered include:
- Scaling Vertically
- Hardware Considerations
- Index Optimization
- Schema Design
- Sharding

Launch Your Streaming Platforms in MinutesRoshan Dwivedi
The claim of launching a streaming platform in minutes might be a bit of an exaggeration, but there are services that can significantly streamline the process. Here's a breakdown:
Pros of Speedy Streaming Platform Launch Services:
No coding required: These services often use drag-and-drop interfaces or pre-built templates, eliminating the need for programming knowledge.
Faster setup: Compared to building from scratch, these platforms can get you up and running much quicker.
All-in-one solutions: Many services offer features like content management systems (CMS), video players, and monetization tools, reducing the need for multiple integrations.
Things to Consider:
Limited customization: These platforms may offer less flexibility in design and functionality compared to custom-built solutions.
Scalability: As your audience grows, you might need to upgrade to a more robust platform or encounter limitations with the "quick launch" option.
Features: Carefully evaluate which features are included and if they meet your specific needs (e.g., live streaming, subscription options).
Examples of Services for Launching Streaming Platforms:
Muvi [muvi com]
Uscreen [usencreen tv]
Alternatives to Consider:
Existing Streaming platforms: Platforms like YouTube or Twitch might be suitable for basic streaming needs, though monetization options might be limited.
Custom Development: While more time-consuming, custom development offers the most control and flexibility for your platform.
Overall, launching a streaming platform in minutes might not be entirely realistic, but these services can significantly speed up the process compared to building from scratch. Carefully consider your needs and budget when choosing the best option for you.

Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

Editor's Notes
Hello, guys. My name is Alex and I work for DataArt as a performance architect. Does someone use Oracle database in your applications? Have you ever used Oracle InMemory option to bring a performance profit?
Perfect.
Today we are going to discuss how we improved faceted search performance with Oracle InMemory option for one of our client.
Let me introduce myself
I work for DataArt as a performance architect and my main focus is data warehousing for big clients. I have huge Oracle experience but I works with Exasol and Tarantool databases either.
My employer is a big software house which is spread all over the world. We have a lot of clients in many industries. Probably you know some of them.
We have rather straightforward agenda for today discussion
We’ll discuss what is faceted search,
client application overview and its performance issues
I try to explain how Oracle InMemory option is implemented internally but without digging into details.
My main focus is how we made the customer happy and share with you our issues you could face with as well
For sure I’ll answer your questions.
Probably you’ve already seen it 5 times today but what I would like to stress that our findings are completely for our case and may be not relevant for you without an thoroughly assesment.
Everybody know what is faceted search.
We have groups named facets,
Values named constraints and
Figures names facet counts
Common facet types are terms
Intervals
And ranges
We need facets if
Users need to filter content using multiple taxonomy terms at the same time.
Users want to combine text searches, taxonomy term filtering, and other search criteria.
trying to discover relationships or trends between contents.
Navigate inside tons of data
And your end users are already frightened by "advanced" search forms in enterprise applications
There are many ways how to implement faceted search internally and one of them is using tags. Everyone knows what is tags but let me reming.
Tag is a keyword assigned to an object
Mostly is is chosen informaly
If it is assigned by the viewer and tags count is unlimited it is folksonomy
When assigned by the creator and a set of tags is limited it is taxonomy
So we could store data for facets in tags which is extremely convenient for terms faceting by folksonomies and taxonomies
Or in a plain table which is very convenient for range, interval facets defined by taxonomies.
I think everything is clear enough but may be you have some questions about theory?
So, let’s move on
We use taxonomy and foksonomy, so the best part of our facets are terms and we choosen tag-based storage.
Let me show some statistics. We extract objects, tags, facets for 2 years
We have about 3 000 000 objects tagged, 42 000 000 terms applied, 100 000 unique terms, maximum tags count is 15 and there are about 150 facets.
Is it whether decent volume or not? I think it is decent because we are bigger than StackOverflow by tags in 3 times.
We have ordinal architecture for enterprise.
Web browser, balancer, a set of application servers which deal with inmemory grid and oracle with the replica on the backend.
Pay attention that there is no full text search server which has been prohibited in accordance with customer policies.
We have microservice architecture and one of the services it tagging service which is responsible for data ingestion and faceted search. It is widely used by many other services and receives about 10000 requests per second. In order to serve search requests there are about 20 fine-tuned sql queries.
I can’t show you real printscreens from the application because of NDA so I implemented the mockup in Paint. As we could see UI is full of features as
Predefined faceted search templates
Full text search by random tags. Here it is done by names. We could search via audit information and we have faceted navigation for sure. We could filter out objects where some tags are present (not tag values) and user paging.
It is rather sophisticated UI.
Without digging into details I could say that the best part of search is made on a wide Denormalized table with tags which stores only current tag values
We could have a look into the table in details. It contains tagged object types, facet information, tags information and values. There is Denormalized object name and object description tags because they are used in full text search mostly.
Let’s have a look into performance metrics. Pay attention the insert performance is very good so I used logarithmic scale to put everything in one diagram. On a first glance figures look good. We do complicated searches less than zero point two seconds but actually it is bad because we need to serve more and more users and data so queries become slow
In accordance with one of my otherspresentations the best option for faceted search is full text search dedicated server but we had a lack of time to implement it as well as reluctant to introduce additional layers
We started looking into InMemory solutions especialy regarding the customer already had Oracle InMemory license. In accordance with Oracle documentation it should be used for analytical queries which isn’t our case completely but we decided to try.
Why we should try
Because we are under limitations preasure
The customer has a license
The table is rather wide, full of data which has a lot of equal values
So it will fit in memory especialy regarding compression features
And last but not least queries are full of aggregate functions
In accordance with the Oracle documentation InMemory feature is sort of silver bullets so we decided not waste time understanding how it works internaly. What we knew that the option stores row and columnar data in dual mode maintaining their consistency automatically.
Let me remind you our table
We set InMemory area size to 10 gigabytes and assigned the table into the area. We decided that performance will be faster without compression so no compression option was used.
What is significant to stress that InMemory brought some overhead without compression
So we started our tests and faced with the difference in performance was extremely unsignificant which is expect for the search by primary keys but not for search by tags

So we started our tests and faced with the difference in performance was extremely unsignificant which is expect for the search by primary keys but not for search by tags
When we started our POC we relied on Lufthansa usecase when they got average 21 performance profit but our profit was 10 times less. It means that we do something wrong and we need to understand how InMemory works internaly.
Do you recall I mentioned InMemory area? It consists from 2 parts actualy.
The first one in IMCU – InMemory Compression Unit which stores data in columnar format
And SMU – Snapshot Metadata Unit which stores transaction related metadata, dictionaries and Zone Maps. Do you know what is zone map?
Let’s have a look into simplified example. We have sales table which is split by 1 Mb IMCU blocks. Each block stores minimal and maximum values for each column so when we need to search sales for California we scans zone maps and check does our value is located in min/max boundaries so we do not scan extra blocks.
I converted SMU zone maps in readable format. As you could see they are stored per-column base as I told before.
You see numeric zone maps and character ones.
Please pay attention that dictionary_entries column contains only zero.
As we understood it happens because no compression were switched on.
Let’s enable the compression
We’ve seen that dictionary extries had been populated which should give dictionary-based pruning in accordance with the documentation
Compression ration is rather high but it depends from you data for sure. You could see that compression doesn’t influence on ingestion so high compression could be used as the default. Frankly speaking loading 6 gigabytes for 1 minute it is to much so we decided to have a look into FastStart feature.
The feature writes InMemory area in a columnar format and once database is rebooted it loads the data in memory with the speed of file reading so we got 3 times loading profit.
It is time for rerun. Try to guess which performance profit we got once we used high compression?
Actually no profit at all.
If we return to our table we will see that we use binary format because of global unique identifiers. Zone Maps were not efficient so we
Changed all types to bigint and removed indexes
We understood that no reasons to store all columns inmemory because we search by them via Oracle Full Text Search indexes
So the final structure is simple data types without b-tree indexes and 2 fields are removed from inmemory storage
We did some performance tests and found sporadic search degradation which happens where records are inserted
Let’s understand how Oracle provides read consistency for InMemory
Once a record is changed it is marked as stale. All stale records are read either from buffer cache or disk.
Oracle repopulates stale records by staleness threshold or each 2 minutes by so named trickle repopulation process. It could be done in parallel plus we could state how much resources could be consumed for stale records repopulation
As soon as we set 4 repopulation servers and 8 percent of time to repopulate stale records and performance spikes disappeared
InMemory option is very easily to trace and maintain but let me share a secret information with you.
We needn’t to know all of them at all.
8 parameters covers the best part of InMemory performance tuning.
Let me share one more secret. only 1 parameter is enough. Try to guess which one. It states how efficient zone maps indexes are used.
3 settings covers the best part of dba activities
And 2 views give us enough information for basic InMemory undertanding
Let’s have a look into final figures. As you could see we have about 4-5 times performance profit which isn’t so good but regarding our use case is fine.

Let’s elaborate DBA findings.
InMemory area size should be estimated taking into account compression and your data
If we have all data in memory it doesn’t mean we are extremely fast
InMemory takes time to be loaded after server reboot
8 statistics is enough to help developers with the best part of their issues
Alling tackle processes settings with your workload
Findings for developers are that in case of our usecase extremely advanced inmemory features like join groups, inmemory aggregations hasn’t brought significant performance profit.
Zone maps work perfect with numeric and date data types.
Dictionary based pruning doesn’t work in our oracle version at least.
More simple data types are used – more performance we have
And extremely significant that high compression doesn’t affect ingestion speed
Faststart
Add some star schema data with star – try what for IM is intended initialy
Tell about cool stuff with multithread scans
Our main conclusion is that you shouldn’t rely on documentation and experts – try and measure your particular use-case
IM works with short queries as well
Without understanding how it works you will not get performance profit
You have to change application to use simple data types
What is good no extra layers, message queues, hardware need to be added
We had managed to put our IM POC in production very fast (1 week actualy)
And business got 5 times performance boost.
Probably that’s it from my side for today.
Thank you for your time and I’m ready answer your questions
