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.

...Traditionally PostgreSQL supports active-standby setups (single writable master), but pgactive opens up use cases such as multi-region high-availability clusters, low-latency writes from distributed apps, and blue/green migrations where both sides are writable. It builds on PostgreSQL’s logical replication framework and offers mechanisms for conflict detection, resolution (e.g., last-write-wins), monitoring of lag and writes across nodes. 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.

MyDumper is a MySQL Logical Backup Tool. It has 2 tools. mydumper which is responsible to export a consistent backup of MySQL databases. myloader reads the backup from mydumper, connects the to destination database and imports the backup. Both tools use multithreading capabilities. MyDumper is Open Source and maintained by the community, it is not a Percona, MariaDB or MySQL product.

Netstore is a scalable high-performance network storage system. The server supports and extends the protocol used by memcached, it is multi-threaded, allows logical separation of storage areas (domains) and hierarchical name spaces.

A knowledge base engine for Python built on F-Logic. It uses the FLORA-2 reasoning engine and provides permanent storage through ZODB. Logic programming concepts like logical variables, facts, rules and queries are included.

KML is a knowledge base with support of logical modeling. Advanced model is used to represent knowledge as a set of statements similar to natural language sentences. This project hosts a set of model storage library and server (vrb-ols) and clients.
