pg_auto_failover is a PostgreSQL extension and management tool for automated high availability. It handles health checks, failover, and monitoring without requiring third-party tools or complex configuration. Designed by the Citus Data team at Microsoft, it's ideal for developers and ops teams wanting reliable HA with minimal effort.

MaxPis will connect to MariaDB MaxScale and monitor up to three selected servers, likely a MariaDB Galera Cluster, and will show the up / down state of each server and indicate the current master on LEDs connected to the Raspberry Pi where the program runs.

...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.

Levin is an event-based key/value server based on radix-tree (space optimized trie). Key search can be performed with an approximate key matching algorithm based on Levenshtein edit distance.

...As a DBMS, RAQUEL is to : 1. have an Open Architecture, enabling a variety of DBMS configurations of 'black box' code, each installation optimised for a certain kind of DB; 2. be a stack of core black boxes to provide general DBMS functionality, plus a range of plug-in black boxes to support different physical storage mechanisms & scalar data types; 3. employ code designed with a mixture of functional, OO & other methods so as to minimise internal DBMS state complexity. The 'Northumbria Website' (above RHS menu option) describes the vision, specification & design of the RAQUEL language & DBMS architecture.

sysbench is a scriptable multi-threaded benchmark tool based on LuaJIT. It is most frequently used for database benchmarks, but can also be used to create arbitrarily complex workloads that do not involve a database server. extensive statistics about rate and latency is available, including latency percentiles and histograms. Low overhead even with thousands of concurrent threads. sysbench is capable of generating and tracking hundreds of millions of events per second. New benchmarks can be...

...Rewrite the network model and the threading model. Optimize the locking mechanism, performance improved immensely. When Atlas start, it will create multiple threads. One of them is the main thread, the others are working threads. The main thread is responsible for monitoring the connecting requests from clients, and the working thread only monitor the command request from the main thread.

Symmetrical Mulitple Databace - Non center, auto spliting, auto backup, auto error recover, data storage and calculation distribute. For large scale web site storage and calculation. Small Server - Simply multiply thread socket server. Nodes are some servers or hosts with fixed ip-port pairs. Nodes are configed with several known friends. Every node maintains a hash table-rbtree data structure that contains the node map information. Nodes can do fast sync with the friends to update this node map. MD4 signiture are used for fast sync. Every working node serves a range. ...

Eleven is a programming language for creating robust, scalable web applications. It offers a 20x programmer productivity increase over ASP, JSP, etc. by automating state management and UI layout. The compiler generates ready-to-run PHP or mod_perl code.

The Trivial Database Replication System is an open source suite of software that provides a high-performance, replicated, distributed peer-to-peer Unix Berkley DBM style database built on TDB. It provides a thread-safe C API.

Muq is a network server that goes several design generations beyond MOO or Java in providing support for applications characterized by these five requirements: Multi-user, Persistent state, Complex data, Complex code, and Distributed networking.

TcpSql is a fast thread-based TCP server for various tasks depending of loaded modules. It uses several persistent database connections for higher performance and reliability (clustering). A server is highly configurable via apache-like config file.
