AjguDB

This program is alpha becarful

AjguDB wants to be a fast enough python graph database for exploring connected data.

Dependencies

storage: only wiredtiger 2.6.1 backend storage is supported
ajgudb: you can threat AjguDB as simple key/value store via its methods AjguDB.get(key), AjguDB.set(key, value) and AjguDB.remove(key)
rewrite gremlin querying
gremlin: select is renamed where because it match the SQL terminology. SQL's FROM is vertices and edges steps.
storage: rework the backend to use less write and similar read operations count.
storage: Now edges and vertices are stored in different tables this might also lead to performance improvement during querying.
storage: elements identifiers are now computed by the backend storage, wiredtiger.
add fuzzy search

ajgudb
- add bsddb backend
- add wiredtiger backend
- leveldb: increase block size to 1GB
gremlin:
- add keys to retrieve several keys at the same time
- use lazy itertools.imap instead of the gready python2's map

ajgudb:
- add a shortcut method AjguDB.one(**kwargs) to query for one element.
gremlin:
- fix group_count, now it's a step and not a final step
- fix each to return GremlinResult so that history is not lost and back can be used
- add scatter, it's only useful after group_count so far.
