tinynpydb _(tiny-en-py-db)_ is a tiny pickle-based numpy array database

The tinynpydb project

tinynpydb (tiny-en-py-db) is a tiny pickle-based numpy array database.

Installing

• From PyPI

  pip install tinynpydb
  

• Simply clone and from within the repo

  pip install -e .
  

Quickstart

Starting a DB is easy:

# import and create example
import tinynpydb as tnpdb

array = [1, 2, 3]

# start DB and dump array!
npdb = tnpdb.NumPyDB('testnpdb', mode="store")
npdb.dump(array, 0)

# retrieve array!
loaded_array = npdb.load(0)
print(loaded_array)

Re-using a DB is easy too:

# import and create example
import tinynpydb as tnpdb

# start DB in loading mode
npdb = tnpdb.NumPyDB('testnpdb', mode="load")

# retrieve array!
loaded_array = npdb.load(0)
print(loaded_array)

That's pretty much all we do

- This was inspired from SciTools NumpyDB implementation
[Scitools github repo](https://github.com/hplgit/scitools)
and we decided to mantain a tiny version of it.

We retain their choice of a 3-BSD License

Method to clean-up/delete db

Add a method that deletes self.dn and self.pn, or automatically delete when class is garbage collected?
