MonetDB/e-Python

MonetDB/e-Python - the serverless Python embedded MonetDB

alt text

Want to store and search a massive amount of numbers? You don't want to run a database service? Is SQLite too slow for what you want to do? Search no further! MonetDBe-Python is here. Just pip install the binary wheel on your Windows, Linux or OS X system and you are ready to go, no compilation needed.

MonetDBe-Python internally relies on a serverless and trimmed-down version of the blazingly fast MonetDB, the open-source column-store database.

The documentation can be found at: https://monetdbe.readthedocs.io/

The source code can be found at: https://github.com/monetdBSolutions/MonetDBe-Python/

install

you need:

  • An up-to-date Linux, OSX or Windows
  • pip >= 19.3
  • Python >= 3.6

to make sure you have a recent pip first upgrade pip:

$ pip install --upgrade pip

now you can install MonetDBe-Python with:

$ pip install monetdbe

usage

Just import and get started, no running a server required. Connecting without an argument starts an in-memory storage instance:

>>> from monetdbe import connect
>>> con = connect()
>>> con.execute('select * from tables').fetchdf()
