[Altibase] 4-5 summary of tablespace management
Disk tablespaces store large amounts of data on disk for processing and use extents and pages to allocate and recover data from datafiles and logfiles. Memory tablespaces provide high performance by storing data in memory using pages and recovering from checkpoint image files and logfiles, supporting compaction of pages.
[Altibase] 13 backup and recovery
Checkpointing saves database status and changes to data files. It reduces recovery time after a fault. Regular checkpointing is performed automatically or manually. Reasons redo logs may not delete after checkpointing include active transactions or archiving in Archivelog mode. Media recovery restores missing or corrupted data files using backups, archive logs, and log anchor files in Archivelog mode.
[Altibase] 12 replication part5 (optimization and monitoring)
The document discusses considerations for optimizing ALTIBASE HDB replication. Key points include optimizing the network, transaction tuning including limiting bulk DML and UPDATE operations, hardware requirements like bandwidth and network cards, software configuration, designing replication objects, handling partial failures and locks, replication sender and receiver tuning, and monitoring replication using internal meta tables and performance views.
[Altibase] 11 replication part4 (conflict resolution)
The document describes different types of replication conflicts that can occur during replication including insert, update, and delete conflicts. It also provides examples of how conflicts may arise from concurrent insert, update, and delete operations on different nodes and how they are resolved. The key methods for resolving replication conflicts include a user-oriented scheme, timestamps-based scheme, and master-slave scheme.
[Altibase] 10 replication part3 (system design)
This document discusses different types of database replication including lazy and eager replication. Lazy replication does not block the master transaction during replication, while eager replication replicates transactions synchronously using two-phase commit. Replication can be active-active, allowing modifications from all nodes, or active-standby, allowing modifications from only the active node. There is a tradeoff between replication delay and performance, with lazy replication having less delay but slower performance than eager replication. The document also provides examples of how to configure different replication topologies depending on the system requirements.
[Altibase] 9 replication part2 (methods and controls)
The document discusses replication in ALTIBASE HDB. It describes the query processor and storage manager roles in handling SQL statements and data. It then summarizes 6 methods for replicating data between servers and explains that method 5, which converts redo logs to a replayable logical form and sends them, has good replication performance with some conversion expense. The document also provides details on replication objects, conditions for replication tables, and commands for creating, controlling, and cloning replication objects and tables.
[Altibase] 8 replication part1 (overview)
This document discusses high availability and database replication techniques. It describes a non-stop service system that aims to minimize downtime through planned and unplanned maintenance. High availability ensures near 100% uptime through techniques implemented at the software and hardware levels. Database replication synchronizes databases across nodes to enable failover. There are two main architectures: shared nothing uses replication over a network while shared disk shares storage. Key considerations in choosing an approach include performance, costs, distance between nodes, and data consistency. The document then outlines the features and benefits of database replication, including its use for high availability, load balancing, and disaster recovery.
[Altibase] 7 how the buffer is managed in altibase
The document discusses database buffering and buffer pool management. It defines key terms like buffer, buffer replacement, and victim. The buffer is a memory space where disk pages are loaded to improve performance. When new pages are loaded, they may replace (victim) existing pages in the buffer. Each buffer frame holds a single disk page. Buffer frames have states like free, clean, or dirty. A buffer control block (BCB) manages metadata for each frame, tracking its state and location on lists like LRU, flush, and prepare lists that help manage replacement and flushing of pages.
[Altibase] 6 what is the mvcc
Concurrency control methods like locking prevent data inconsistencies when multiple transactions access the same data concurrently. There are two main concurrency control techniques: single-version concurrency control (SVCC) and multi-version concurrency control (MVCC). SVCC uses locking and only maintains a single version of each record, while MVCC creates new versions of records during updates to allow concurrent read and write operations without locking. MVCC has better performance for environments with frequent transactions.
[Altibase] 5 durability
A transaction is a logical unit of work that consists of one or more SQL statements. Transaction management controls concurrency and maintains data consistency by ensuring transactions have the properties of atomicity, consistency, isolation, and durability (ACID). Transaction durability guarantees that committed transactions persist even after a system failure by writing log records to disk before acknowledging the commit. There is a tradeoff between high durability, which ensures data safety but reduces performance, and lower durability, which improves performance but reduces safety in the event of certain failures.
[Altibase] 4-4 disk tablespace
Space in disk tablespaces is allocated in 256K extents to tables, with pages having a status of free or used. DELETE changes used page status to free within a table, while TRUNCATE returns all allocated pages to the tablespace as free for any table to use. MOVE has the same effect as DELETE by keeping pages free within the table. Compaction cannot be done on disk tables.
[Altibase] 4-3 volatile tablespace
This document describes a volatile tablespace in Oracle Database. A volatile tablespace stores data only in memory with no disk-resident components like checkpoint image files or logs. This provides the highest performance for data manipulation language operations compared to other tablespaces because there is no disk input/output or logging involved.
[Altibase] 4-2 memory tablespace
Memory tablespaces store memory-resident data and use checkpoint image files on disk to recover that data if needed. Space in a memory tablespace is allocated in 32KB pages that have a status of either free or used. When data is deleted from a table, the empty pages' status changes to free within that table but they are not returned to the tablespace until compaction. Truncating a table returns all its pages to the tablespace as free.
[Altibase] 4-1 tablespace concept
Tablespaces are the logical structures that store database objects like tables and indexes. A database consists of one or more tablespaces, with each tablespace made up of segments, extents, and pages stored either in memory or on disk. Altibase provides different types of tablespaces classified by data properties like memory or disk, and by time of creation as either system or user tablespaces.
[Altibase] 3-3 directory contents
The $ALTIBASE_HOME directory contains various subdirectories that store important Altibase files including configuration files, data files, log files, library files, sample programs, and trace files. Key subdirectories include bin for execution files, conf for configuration files, lib for library files, include for header files, logs for redo log and anchor files, and trc for trace files recording the current Altibase status. The directory also contains utilities like Audit for data replication consistency checks and directories for archived logs, messages, and database samples.
[Altibase] 2-4 sql functions
AltiBase HDB supports standard SQL features such as subqueries, joins, hierarchical queries, array processing, and DML operations on views. It does not support some object-oriented features from ANSI-SQL1999 and parallel selects, though it can perform parallel inserts and index builds.

Altibase HDB supports stored procedures, functions, packages, views, sequences, queues, monitoring views, roles, DB links, synonyms, table partitioning, user defined types in procedures, cluster objects, on-line backup, XML, and auto-extending databases. Triggers are supported except before update triggers, and materialized views but not snapshots are supported.
[Altibase] 2-2 Altibase storage
A database consists of one or more tablespaces which can be either memory or disk tablespaces. A memory tablespace contains 32KB pages while a disk tablespace contains 8KB pages organized into segments, extents, and pages. Segments in disk tablespaces contain multiple 512KB extents which each contain 64 pages.
[Altibase] 2-1 features
AltiBase HDB is a relational, client-server DBMS that uses multi-threading and supports high availability through replication at the table level, with separate instances, individual storage, and schemas for each replicated data set. It supports 64-bit mode, row-level locking with MVCC, recovery from datafiles and redo logfiles with automatic deadlock detection and recovery.
[Altibase] 1-5 hybrid dbms
Hybrid DBMS combines an in-memory and disk-based database management system (DBMS) so that users only need to access a single DBMS rather than separate in-memory and disk DBMS. It stores data and tables both in memory and disk storage layers with the Altibase HDB managing the data across the different storage mediums in a unified manner for users.

Hand Rolled Applicative User Validation Code Kata
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

Graspan: A Big Data System for Big Code Analysis
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.
- Accepted in ASPLOS ‘17, Xi’an, China.
- Featured in the tutorial, Systemized Program Analyses: A Big Data Perspective on Static Analysis Scalability, ASPLOS ‘17.
- Invited for presentation at SoCal PLS ‘16.
- Invited for poster presentation at PLDI SRC ‘16.

Need for Speed: Removing speed bumps from your Symfony projects ⚡️
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.
