Citus
Distributed PostgreSQL as an extension
Citus is a PostgreSQL extension that transforms Postgres into a distributed database, so you can achieve high performance at any scale. With Citus, you extend your PostgreSQL database with new superpowers. Distributed tables are sharded across a cluster of PostgreSQL nodes to combine their CPU, memory, storage and I/O capacity. References tables are replicated to all nodes for joins and foreign keys from distributed tables and maximum read performance. Distributed query engine routes and parallelizes SELECT, DML, and other operations on distributed tables across the cluster. ... -

pglogical
Logical Replication extension for PostgreSQL
pglogical is an advanced logical replication extension for PostgreSQL that allows selective replication of data between databases. Unlike physical replication, it enables fine-grained control of which tables or changes to replicate. It’s well-suited for multi-master setups, version upgrades, and real-time data distribution across environments. -

pg_squeeze
A PostgreSQL extension for automatic bloat cleanup
pg_squeeze is a PostgreSQL extension that reclaims space in bloated tables without blocking read or write access. It provides a non-intrusive alternative to VACUUM FULL by creating a new compacted copy of the table in the background. It’s particularly useful for maintaining performance in large, heavily updated databases. -

pgactive
PostgreSQL replication extension to create an active-active database
...Because active-active replication introduces new complexity (conflicts, schema changes, write amplification), pgactive provides tools for managing replication sets, conflict logging tables, and administrative commands to detach nodes or remove the extension. -

WCDB
Cross-platform database framework developed by WeChat
...WINQ (WCDB language integrated query), WINQ is a native data querying capability which frees developers from writing glue code to concatenate SQL query strings. ORM (Object Relational Mapping), WCDB provides a flexible, easy-to-use ORM for creating tables, indices and constraints, as well as CRUD through ObjC objects. Efficient. Through the framework layer and sqlcipher source optimization, WCDB have more efficient performance. Multi-threaded concurrency, WCDB supports concurrent read-read and read-write access via connection pooling. ORM/persistence solution via Room from Android Architecture Components. ... -

mariadb_sysinfo
Plugin for MariaDB to get system hardware information and measurement
This basic information_schema plugin provides two I_S tables: * SYSINFO - This contains CPU, MEMORY and some other hardware information on the server that MariaDB runs on. * SENSORS - This table show current measurements on hardware, using the sensors API, such as CPU temperature etc. What information is shown depends on what is available on the hardware in question -

nonblonde
A Key/data Store
Nonblonde is a key/value database. Nonblonde tables are backed by b-trees that organize their nodes as critical bit trees. It allows multiple tables per store, atomic updates, keys of unlimited size. Head and tail key compression and a variable block size reduce the database disk size. Disk blocks are never modified in place, for which the written database is always in an intended state and does not need repair or recovery. -

meta-treedb
on-disk memory library using meta-data
...Meta-treedb comes with an AVL tree, doubly-linked-list and variable-entry-sized-array implementations for you to use in your data structures. So, what distinguishes meta-treedb from treedb? * "class" interfaces for treedb collections These are vtables (virtual function tables) that implement the interface. * faster compiles - only the "class" interfaces are visible to client code This is at the expense of a small performance hit. * the ability to use implementations that were developed after client code was compiled. -

pg_reorg
Online Table Clustering Tool for PostgreSQL
pg_reorg can re-organize tables on a PostgreSQL database without keeping any locks so that you can retrieve or update rows in tables being reorganized. This module is developed to be a better alternative of CLUSTER and VACUUM FULL. ------- pg_reorg was located in pgfoundry, but has been moved to here temporally. ************************************ 2015.07.03 Now, we are moving to GitHub. -

OraMySQL
A simple set of programs to sync Oracle to a MySQL database
If you have just a small number of Oracle tables that you want to sync to a MySQL database, then this might be what you want. It is really simple. The concept is to add a small extproc to Oracle that sends UDP messages and then have a receiver for those messages that applies whatever it gets to MySQL. This is simple, but effective, but is also has a few drawbacks. But if you can live with them, this might be just what you are looking for. -
