...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. To achieve top performance, Redis works with an in-memory dataset. Depending on your use case, you can persist your data either by periodically dumping the dataset to disk or by appending each command to a disk-based log.

pg_pathman is a PostgreSQL extension that provides high-performance partitioning support, developed by PostgresPro. It improves query planning and execution speed for partitioned tables by introducing advanced partition pruning and runtime optimization strategies. It’s ideal for large datasets that require fine-tuned partition control.

GNU libdbh. As of April 9, 2014, DBH is a GNU program and is renamed to "GNU libdbh". Library to create and manage 64-bit disk based hash tables Associations are made between keys and values so that for a given a key the value can be found and loaded into memory quickly: 64 bit support

...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.

The Open Extract Processor (OEP) is a database ETL utility capable of merging/sorting/aggregating large partitioned database extracts. Native data files can be created from text files or from the accompanying MYSQL and Oracle import/export programs.

Tokyo Cabinet is the successor of QDBM, a high performance database library similar to the DBM family. It also supports hash and B-tree databases and does not require any server process. The overall speed is improved compared to QDBM.

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

CTNHashProc is a Microsoft SQLServer 2000 Extended Stored Procedure that returns the hash of a given string. Currently the supported hash functions are SHA (SHA1), SHA2 (SHA-256, SHA-384, SHA-512), MD5, RIPEMD-160, Tiger.

ReHash is an easy-to-use console-based hash calculation tool written in C++. It supports many algorithms and output formats and it can be fully configured using some of the many command-line arguments which can be passed to the tool.

A program to manage hash databases; gdbm databases etc. It performs simple operations on them; insert new records, remove records, list records etc. It is intended primarily as a programmer's aid, when writing programs based on these databases. It has a
