24 May | Indexes in PostgreSQL — 4 (Btree)

We will now consider B-tree, the most traditional and widely used index. This article is large, so be patient.

23 May | Indexes in PostgreSQL — 3 (Hash)

Now we are ready to discuss specific types of indexes. Let's start with hash index.

22 May | Indexes in PostgreSQL — 2

Let's look into the structure of the access method interface.

pg_pathman

The pg_pathman module provides optimized partitioning mechanism and functions to manage partitions.

pg_variables

Functions for defining and using variables in client sessions.

JsQuery

JsQuery – is a language to query jsonb data type, introduced in PostgreSQL release 9.4. It's primary goal is to provide an additional functionality to jsonb (currently missing in PostgreSQL), such as a simple and effective way to search in nested objects and arrays, more comparison operators with indexes support.

pg_probackup

Pg_probackup is a utility to manage backup and recovery of PostgreSQL database clusters. It is designed to perform periodic backups of the PostgreSQL instance that enable you to restore the server in case of a failure.

Backup

We work on several backup problems: block-level incremental backup, backup validation, partial backup/restore.

JIT compilation of queries

Current approach for execution is essentially a kind plan tree interpretation. JIT-compilation of queries means compilation of plan tree into binary. Such compilation could get rid of multiple levels of indirection therefore accelerating queries.

Adaptive query planning

We develop new algorithms to make the query plans better.
