ChangeLog

0.8.1

• improve documentation
• fix scatter step
• improve test coverage (89%)
• more experience with conceptnet

0.8

• move to tuple space implementation
• work with wiredtiger develop branch

0.7.1

• small typofix in README…

0.7

• 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

0.5

• 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

0.4.2

• 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.
