Tritcask

You can never have enough key value stores that are:

• 100% python
• based on bitcask
• very fast (3x to 100x vs SQLite)
• crash friendly
• tested on millions of desktops for the Ubuntu One file sync client

Sample usage

Create a database

import tritcask
db = tritcask.Tritcask("/tmp/tcask")

Put and get and kill some database

>>> db.put(0, "hello", "data")
>>> db.keys()
[(0, 'hello')]
>>> db.get(0, "hello")
'data'
>>> db.delete(0, 'hello')
>>> db.keys()
[]

And it's fast:

In [1]: time for i in xrange(10000): db.put(0, str(i), str(i))
CPU times: user 124 ms, sys: 52 ms, total: 176 ms
Wall time: 175 ms
