pgactive
PostgreSQL replication extension to create an active-active database
...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. -

pgstream
PostgreSQL replication with DDL changes
pgstream is an open source CDC command-line tool and library that offers Postgres replication support with DDL changes to any provided output. One of the main differentiators of pgstream is the fact that it tracks and replicates schema changes automatically. It relies on SQL triggers that will populate a Postgres table (pgstream.schema_log) containing a history log of all DDL changes for a given schema. Whenever a schema change occurs, this trigger creates a new row in the schema log table with the schema encoded as a JSON value. ... -

Redis
An in-memory database that persists on disk
...Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams. Redis has built-in replication, Lua scripting, LRU eviction, transactions, and different levels of on-disk persistence, and provides high availability via Redis Sentinel and automatic partitioning with Redis Cluster. You can run atomic operations on these types, like appending to a string; incrementing the value in a hash; pushing an element to a list; computing set intersection, union and difference; or getting the member with highest ranking in a sorted set. ... -
