SessionServer
(basedir, autosession=True, use_locks=True)[source]¶ Similarity server on top of
SimServer
that implements sessions = transactions.A transaction is a set of server modifications (index/delete/train calls) that may be either committed or rolled back entirely.
Sessions are realized by:
- cloning (=copying) a SimServer at the beginning of a session
- serving read-only queries from the original server (the clone may be modified during queries)
- modifications affect only the clone
- at commit, the clone becomes the original
- at rollback, do nothing (clone is discarded, next transaction starts from the original again)
