pgactive is an open-source extension for PostgreSQL that enables active-active replication across multiple database instances—meaning each node can accept writes and replicate changes to other nodes. 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. ...

...Hyperfunctions make time series easier. Achieve 10-100x faster queries than with vanilla PostgreSQL, InfluxDB, MongoDB. Write millions of data points per second per node. Horizontally scale to petabytes. Don’t worry about cardinality. Simplify your stack, ask more complex questions, and build more powerful applications. Don’t break the bank. 94-97% compression rates from best-in-class algorithms. Downsample + retention policies. Decouple compute and storage. You’re in trusted hands. Fully-managed TimescaleDB on AWS, Azure, or GCP in just one click. ...

Small client/server SQL system with terminal based client. Requires Linux running systemd. See README for more info. Written in C++.

repmgr is a management tool for PostgreSQL replication, providing monitoring, failover, and administrative capabilities for streaming replication setups. It simplifies the configuration of primary/standby clusters and automates failover processes for high availability. repmgr is widely used in production environments where database resilience and minimal downtime are critical.

...Columnar storage compresses data, speeds up scans, and supports fast projections, both on regular and distributed tables. You can use these Citus superpowers to make your Postgres database scale-out ready on a single Citus node.

Very simple struct storage system, AVL and red-black tree based database library - database engine. You can define indexes over C struct.

Sedna is a free native XML database which provides a full range of core database services - persistent storage, ACID transactions, security, indices, hot backup. Flexible XML processing facilities include W3C XQuery implementation, tight integration of XQuery with full-text search facilities and a node-level update language.

...The ranges would be able to cover the complete 0 ~ 0xffffffff area. That makes every hash result could find a responser node. Beside the node map, a pie-slice map is also be recorded by every node. The pie-slice map is designed for fast range node finding and automatic spliting.

set of utilities that provide high availability for databases using the mysql database server. includes ip address takeover, using a master node and a slave one. please send you feature requests to fipar@seriema-systems.com

A library providing basic building blocks for creating in-memory databases of important data. Existing components are: Linked lists; Hash tables with optional auto-resize; Memory-efficient sparse matrices built on hash tables; Red-black trees. NOTE: This project is moving to Github; https://github.com/klmitch/dbprim

The cache-optimized concurrent skip list is a set of algorithms for maintaining dynamic ordered mappings. Top-down balancing algorithms minimize cache-misses while using a per-node read-write spinlock to coordinate shared access. Designed for Linux 2.4.

iCE Breakers MySQL Monitor will allow administrators to monitor the status of their MySQL servers. If a run-away query appears in the list, the query row will turn yellow and then red to notifying the administrator that there's a problem. The administr
