The CAP theorem is widely known for distributed systems, but it's not the only tradeoff you should be aware of. For datastores, there is also the FAB theory and just like with the CAP theorem you can only pick two:
Fast: Results are real-time or near real-time instead of batch-oriented.
Accurate: Answers are exact and don't have a margin of error.
Big: You require horizontal scaling and need to distribute your data.
While Fast and Big are relatively easy to understand, Accurate is a bit harder to picture. This talk shows some concrete examples of accuracy tradeoffs Elasticsearch can take for terms aggregations, cardinality aggregations with HyperLogLog++, and the IDF part of the full-text search. Or how to trade some speed or the distribution for more accuracy.
Terraform is an Infrastructure as Code tool for declaratively building and maintaining complex infrastructures on one or more cloud providers/services. But Terraform also supports over 80 non-infrastructure providers! In this demo-driven talk, will dive into the internals of Terraform and see how it works. We will show how Terraform can be used for non-infrastructure use cases by showing examples. We’ll also take a look at on how you can extend Terraform to manage anything with an API.

Through these examples we'll see how ASTs can be great for analyzing and even for modifying your JavaScript. This talk should be interesting to anyone that regularly builds apps in JavaScript either on the client-side or on the server-side.
Practical Elasticsearch - real world use casesItamar
Elasticsearch - a search and real-time analytics server based on Apache Lucene - is gaining a lot of popularity lately, and is being used world-wide to power many sophisticated systems. While many use it for the "standard" stuff (that is, simple full-text search and real-time log analysis), there are some really interesting usage patterns that can prove useful in many real-world scenarios. In this talk we will briefly talk about Elasticsearch and its common use-cases, and then showcase some less common use-cases leveraging Elasticsearch in an interesting and often times innovating ways.
In this webinar we covered how to improve search with analytics using the Elastic Stack: ElasticSearch, Logstash, Kibana. Check out our upcoming events: www.mcplusa.com/events

Making your elastic cluster perform - Jettro Coenradie - Codemotion Amsterdam...Codemotion
In the past few years I have helped a lot of customers optimising their elastic cluster. With each version elasticsearch has more options to track performance of your nodes and recently profiling your queries was added. In this talk I am going to discuss the steps you have to take when starting with elasticsearch. The choices you have to make for the size of your cluster, the amount of indexes, amount of shards, choosing the right mappings, and creating better queries. After the setup I'll continue showing how to monitor your cluster and profile your queries.
An online training course run by the FIWARE Foundation in conjunction with the i4Trust project. The core part of this virtual training camp (21-24 June 2021) covered all the necessary skills to develop smart solutions powered by FIWARE. It introduces the basis of Digital Twin programming using linked data concepts - JSON-LD and NGSI-LD and combines these with common smart data models for the sharing and augmentation of context data.
In addition, it covers the supplementary FIWARE technologies used to implement the common functions typically required when architecting a complete smart solution: Identity and Access Management (IAM) functions to secure access to digital twin data and functions enabling the interface with IoT and 3rd systems, or the connection with different tools for processing and monitoring current and historical big data.
This 12-hour online training course can be used to obtain a good understanding of FIWARE and NGSI Interfaces and form the basis of studying for the FIWARE expert certification.
Extending this core part, the virtual training camp adds introductory and deep-dive sessions on how FIWARE and iSHARE technologies, brought together under the umbrella of the i4Trust initiative, can be combined to provide the means for the creation of data spaces in which multiple organizations can exchange digital twin data in a trusted and efficient manner, collaborating in the creation of innovative services based on data sharing. In addition, SMEs and Digital Innovation Hubs (DIHs) that go through this complete training and are located in countries eligible under Horizon 2020 will be equipped with the necessary know-how to apply to the recently launched i4Trust Open Call.
Elasticsearch (R)Evolution — You Know, for Search… by Philipp Krenn at Big Da...Big Data Spain
Elasticsearch is a distributed, RESTful search and analytics engine built on top of Apache Lucene. After the initial release in 2010 it has become the most widely used full-text search engine, but it is not stopping there. The revolution happened and now it is time for evolution. We dive into current improvements and new features — how to make a great product even better.

Attack monitoring using ElasticSearch Logstash and KibanaPrajal Kulkarni
With growing trend of Big data, companies are tend to rely on high cost SIEM solutions. However, with introduction of open source and lightweight cluster management solution like ElasticSearch this has been the highlight of the year. Similarly, the log aggregation has been simplified by logstash and kibana providing a visual look to the complex data structure. This presentation will exactly cater to this need of having a appropriate log analysis+Detecting Intrusion+Visualizing data in a powerful interface.

Elasticsearch is a distributed, RESTful search and analytics engine built on top of Apache Lucene. After the initial release in 2010 it has become the most widely used full-text search engine, but it is not stopping there.
The revolution happened and now it is time for evolution. We dive into the following questions:
- What are shards, how do they work, and why are they making Elasticsearch so fast?
- How do shard allocations (which were hard to debug even for us) work and how can you find out what is going wrong with them?
- How can you search efficiently across clusters and why did it take two implementations to get this right?
- How can new resiliency features improve recovery scenarios and add totally new features?
- Why are types finally disappearing and how are we avoid upgrade pains as much as possible?
- How can upgrades be improved so that fewer applications are stuck on old or even ancient versions?

The ColumnFamily data model and wide-row support provides the ability to store and access data efficiently in a de-normalized state. Recent enhancements for CQL's spare tables and built-in indexing provide the capability to store data in a manner similar to that of relational databases. For many use cases hybrid approaches are needed, because complete de-normalization is appropriate for some access patterns whereas more structured data is appropriate for others. At times a single logical event becomes multiple insertions across multiple column families. Likewise a user request might require a several reads across different column families. This talk describes some of these scenarios and demonstrates how advanced operations such multiple step procedures, filtering, intersection, and paging can be implemented client side or server side with the help of the IntraVert plugin.

Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.

The Building Blocks of QuestDB, a Time Series Databasejavier ramirez
Talk Delivered at Valencia Codes Meetup 2024-06.
Traditionally, databases have treated timestamps just as another data type. However, when performing real-time analytics, timestamps should be first class citizens and we need rich time semantics to get the most out of our data. We also need to deal with ever growing datasets while keeping performant, which is as fun as it sounds.
It is no wonder time-series databases are now more popular than ever before. Join me in this session to learn about the internal architecture and building blocks of QuestDB, an open source time-series database designed for speed. We will also review a history of some of the changes we have gone over the past two years to deal with late and unordered data, non-blocking writes, read-replicas, or faster batch ingestion.
