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).

RocksDB is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it specially suitable for storing multiple terabytes of data in a single database. RocksDB is partially based on LevelDB.

Tortoise ORM is an easy-to-use asyncio ORM (Object Relational Mapper) inspired by Django. Tortoise ORM was built with relations in mind and admiration for the excellent and popular Django ORM. It's engraved in its design that you are working not with just tables, you work with relational data.

This package provides a Postgres SQL parser as a library.

SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that gives application developers the full power and flexibility of SQL. It provides a full suite of well known enterprise-level persistence patterns, designed for efficient and high-performing database access, adapted into a simple and Pythonic domain language.

TinyDB is a small document oriented database written in pure Python with no external dependencies. The targets are small apps that would be blown away by a SQL-DB or an external database server.

Prisma Client Python is an auto-generated and fully type-safe database client.

asyncmy is a fast asyncio MySQL driver, which reuses most of pymysql and aiomysql but rewrites the core protocol with Cython for performance.

This package provides a CLI tool and Python utility functions for manipulating SQLite databases. It's main features are:

• Pipe JSON (or CSV or TSV) directly into a new SQLite database file, automatically creating a table with the appropriate schema.

• Run in-memory SQL queries, including joins, directly against data in CSV, TSV or JSON files and view the results.

• Configure SQLite full-text search against your database tables and run search queries against them, ordered by relevance.

• Run transformations against your tables to make schema changes that SQLite ALTER TABLE does not directly support, such as changing the type of a column.

• Extract columns into separate tables to better normalize your existing data.

This package provides Guile bindings to the WiredTiger ``NoSQL'' database.

pg_tmp creates temporary PostgreSQL databases, suitable for tasks like running software test suites. Temporary databases created with pg_tmp have a limited shared memory footprint and are automatically garbage-collected after a configurable number of seconds (the default is 60).

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.

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

Memcached is an in-memory key-value store. It has a small and generic API, and was originally intended for use with dynamic web applications.

This package provides a program to build Entity Relationship diagrams from a SQLAlchemy model (or directly from the database).

Pypika-tortoise is a fork of pypika which has been streamlined for its use in the context of tortoise-orm. It removes support for many database kinds that tortoise-orm doesn't need, for example.

GNU Recutils is a set of tools and libraries for creating and manipulating text-based, human-editable databases. Despite being text-based, databases created with Recutils carry all of the expected features such as unique fields, primary keys, time stamps and more. Many different field types are supported, as is encryption.

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.

This package implements the LSP for SQL.

dicedb-cli is a command line interface for DiceDB, a Redis-compliant in-memory database.

This package provides a Python client library for CrateDB. It implements the Python DB API 2.0 specification and includes support for SQLAlchemy.

Mutastructura provides a familiar, declarative and transactional approach to managing database states. It exposes a user-friendly CLI and has support for PostgreSQL, MySQL, and SQLite. It also exposes library functions and can be imported and used directly from other Guile code.

Features include executing migrations transactionally and computing SHA256 checksums to track schema evolution in a migrations_history table.

This package provides a database interface for Perl.

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.
