...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.

HypoPG is a PostgreSQL extension that allows you to create hypothetical indexes without actually building them on disk. It helps developers and DBAs test the impact of potential indexes on query performance before committing resources. By simulating indexes, HypoPG assists in query optimization and index strategy planning without any performance or storage cost.

Dqlite is a fast, embedded, persistent SQL database with Raft consensus that is perfect for fault-tolerant IoT and Edge devices. Dqlite (distributed SQLite) extends SQLite across a cluster of machines, with automatic failover and high-availability to keep your application running. It uses C-Raft, an optimised Raft implementation in C, to gain high-performance transactional consensus and fault tolerance while preserving SQlite’s outstanding efficiency and tiny footprint. Stable Golang client...

...Nonblonde tables are backed by b-trees that organize their nodes as critical bit trees. It allows multiple tables per store, atomic updates, keys of unlimited size. 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.

Native port of Redis for Windows. Redis is an in-memory database that persists on disk. The data model is key-value, but many different kind of values are supported, Strings, Lists, Sets, Sorted Sets, Hashes, Streams, HyperLogLogs. This repository contains an unofficial port of Redis to Windows. At the moment win-4.0.14 branch provides a stable port of Redis 4.0.14 for Windows x64 and win-5.0 branch provides a stable port of Redis 5.0.14 for Windows x64, both merged with archived port of win-3.2.100 version from MS Open Tech team. ...

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

cstore_fdw is a columnar store extension for PostgreSQL built by Citus Data using the Foreign Data Wrapper (FDW) interface. It stores data in a compressed, columnar format that significantly reduces disk I/O for analytical queries. Ideal for read-heavy workloads and time-series data, cstore_fdw enhances Postgres’ ability to serve as a lightweight data warehouse.

...UnQLite is an embedded NoSQL (Key/Value store and Document-store) database engine. Unlike most other NoSQL databases, UnQLite does not have a separate server process. UnQLite reads and writes directly to ordinary disk files. A complete database with multiple collections is contained in a single disk file. The database file format is cross-platform, you can freely copy a database between 32-bit and 64-bit systems or between big-endian and little-endian architectures. UnQLite is a Self-Contained C library without dependency. Built with a powerful disk storage engine which support O(1) lookup.

meta-treedb can implement malloc functionality, and much more! Need a heap that allocates from a fixed size chunk of memory? No problem. But where treedb comes into its own is when it comes to allocating from a mmap()ed disk file - the memory becomes persistent. If you follow the tests/examples, you too can store dictionaries, trees, lists or whatever you can think of in disk-based memory, just an open() and mmap() away. Meta-treedb comes with an AVL tree, doubly-linked-list and variable-entry-sized-array implementations for you to use in your data structures. ...

sakilaBackup is freeware MySQL Backup automation software.

Hyppocampus is a relational filesystem, which uses the hard disk as an unique database accessible with SQL queries.

A small abstracted database-like dynamic data structure written in C. Can read and write to disk in a manner easily editable by text editors. The structure is intended for C/C++ developers who require a small, yet fast and flexible, data storage method.
