Databases provides a wrapper around asynchronous database libraries with SQLALchemy.

fastparquet is a Python implementation of the Parquet file format. fastparquet is used implicitly by dask, pandas and intake-parquet. It supports the following compression algorithms:

• Gzip

• Snappy

• Brotli

• LZ4

• Zstd

• LZO (optionally)

PostgreSQL is a powerful object-relational database system. It is fully ACID compliant, has full support for foreign keys, joins, views, triggers, and stored procedures (in multiple languages). It includes most SQL:2008 data types, including INTEGER, NUMERIC, BOOLEAN, CHAR, VARCHAR, DATE, INTERVAL, and TIMESTAMP. It also supports storage of binary large objects, including pictures, sounds, or video.

RQ (Redis Queue) is a simple Python library for queueing jobs and processing them in the background with workers. It is backed by Redis and it is designed to have a low barrier to entry.

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

This package provides an Emacs major mode rec-mode for working with GNU Recutils text-based, human-editable databases. It supports editing, navigation, and querying of recutils database files including field and record folding.

MySQLdb is an interface to the popular MySQL database server for Python. The design goals are:

1. Compliance with Python database API version 2.0 [PEP-0249],

2. Thread-safety,

3. Thread-friendliness (threads will not block each other).

FreeTDS is an implementation of the Tabular DataStream protocol, used for connecting to MS SQL and Sybase servers over TCP/IP.

CLI and C/C++ source libraries for DuckDB, a relational (table-oriented) DBMS that supports SQL, contains a columnar-vectorized query execution engine, and provides transactional ACID guarantees via bulk-optimized MVCC. Data can be stored in persistent, single-file databases with support for secondary indexes.

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.

Python-hiredis is a python extension that wraps protocol parsing code in hiredis. It primarily speeds up parsing of multi bulk replies.

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 vector similarity search extension for Postgres. Store your vectors with the rest of your data. It supports:

• exact and approximate nearest neighbor search;

• L2 distance, inner product, and cosine distance;

• any language with a Postgres client.

DBIx::Class::Cursor::Cached provides a cursor class with built-in caching support.

This package is a Sphinx extension providing additional coroutine-specific markup.

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

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

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.

psycopg2 is a thread-safe PostgreSQL adapter that implements DB-API 2.0.

This package provides a PostgreSQL driver for the Perl5 Database Interface (DBI).

DBD::SQLite is a Perl DBI driver for SQLite, that includes the entire thing in the distribution. So in order to get a fast transaction capable RDBMS working for your Perl project you simply have to install this module, and nothing else.

This package contains type stubs and a mypy plugin to provide more precise static types and type inference for SQLAlchemy framework.

SQLAlchemy-utils provides various utility functions and custom data types for SQLAlchemy. SQLAlchemy is an SQL database abstraction library for Python.

You might also want to install the following optional dependencies:

1. python-passlib

2. python-babel

3. python-cryptography

4. python-pytz

5. python-psycopg2

6. python-furl

7. python-flask-babel

Sqlparse is a non-validating SQL parser for Python. It provides support for parsing, splitting and formatting SQL statements.
