The MariaDB Connector/C is used to connect applications developed in C/C++ to MariaDB and MySQL databases.

Pebble is a LevelDB/RocksDB inspired key-value store focused on performance and internal usage by CockroachDB. Pebble inherits the RocksDB file formats and a few extensions such as range deletion tombstones, table-level bloom filters, and updates to the MANIFEST format.

DBIx::Class::DeploymentHandler is a tool for deploying and upgrading databases with DBIx::Class. It is designed to be much more flexible than DBIx::Class::Schema::Versioned, hence the use of Moose and lots of roles.

PyPika is a python SQL query builder that exposes the full richness of the SQL language using a syntax that reflects the resulting query.

SOCI is an abstraction layer for several database backends, including PostreSQL, SQLite, ODBC and MySQL.

litecli is a command-line client for SQLite databases that has auto-completion and syntax highlighting.

WiredTiger is an extensible platform for data management. It supports row-oriented storage (where all columns of a row are stored together), column-oriented storage (where columns are stored in groups, allowing for more efficient access and storage of column subsets) and log-structured merge trees (LSM), for sustained throughput under random insert workloads.

Valkey is a high-performance key-value datastore that supports a variety of workloads such as caching, message queues, and can act as a primary database.

This package provides a Python interface to the Redis key-value store.

Cassandra Cluster Manager is a development tool for testing local Cassandra clusters. It creates, launches and removes Cassandra clusters on localhost.

MySQL::Config emulates the load_defaults function from libmysqlclient. It will fill an array with long options, ready to be parsed by Getopt::Long.

Kyoto Cabinet is a standalone file-based database that supports Hash and B+ Tree data storage models. It is a fast key-value lightweight database and supports many programming languages. It is a NoSQL database.

lmdbxx is a comprehensive C++ wrapper for the LMDB embedded database library, offering both an error-checked procedural interface and an object-oriented resource interface with RAII semantics.

Apache Arrow is a columnar in-memory analytics layer designed to accelerate big data. It houses a set of canonical in-memory representations of flat and hierarchical data along with multiple language-bindings for structure manipulation. It also provides IPC and common algorithm implementations.

Pebble is a LevelDB/RocksDB inspired key-value store focused on performance and internal usage by CockroachDB. Pebble inherits the RocksDB file formats and a few extensions such as range deletion tombstones, table-level bloom filters, and updates to the MANIFEST format. This package provides command line interface (CLI).

This library implements a database independent abstraction layer in C, similar to the DBI/DBD layer in Perl. Writing one generic set of code, programmers can leverage the power of multiple databases and multiple simultaneous database connections by using this framework.

PickleShare is a small ‘shelve’-like datastore with concurrency support. Like shelve, a PickleShareDB object acts like a normal dictionary. Unlike shelve, many processes can access the database simultaneously. Changing a value in database is immediately visible to other processes accessing the same database. Concurrency is possible because the values are stored in separate files. Hence the “database” is a directory where all files are governed by PickleShare.

The DB::File module provides Perl bindings to the Berkeley DB version 1.x.

Tokyo Cabinet is a library of routines for managing a database. The database is a simple data file containing records, each is a pair of a key and a value. Every key and value is serial bytes with variable length. Both binary data and character string can be used as a key and a value. There is neither concept of data tables nor data types. Records are organized in hash table, B+ tree, or fixed-length array.

Yoyo is a database schema migration tool. Migrations are written as SQL files or Python scripts that define a list of migration steps.

This package provides a utility for dumping the contents of an ElasticSearch index to a compressed file and restoring the dumpfile back to an ElasticSearch server

This package provides mock helpers for SQLAlchemy that makes it easy to mock an SQLAlchemy session while preserving the ability to do asserts.

Normally Normally SQLAlchemy's expressions cannot be easily compared as comparison on binary expression produces yet another binary expression, but this library provides functions to facilitate such comparisons.

pgloader is a program that can load data or migrate databases from CSV, DB3, iXF, SQLite, MS-SQL or MySQL to PostgreSQL.

This package provides a Ruby client that tries to match Redis' API one-to-one, while still providing an idiomatic interface.
