Append only (type,key)/value store based on bitcask paper.
Project description
- 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
