0.5.x (master)

New features

  • Multi-cursors: join trails over multiple TrailDBs efficiently. This is a convenient way to stich together e.g. time-sharded TrailDBs or merge together user profiles stored under separate UUIDs.

  • Item index for tdb CLI. This can speed up --filter expressions that access infrequent items significantly.

  • Added tdb_event_filter_num_clauses and tdb_event_filter_get_item for reading items and clauses in an existing filter.

  • TDB_OPT_EVENT_FILTER option for tdb_set_opt which can be used to create views or materialized views.

  • --filter flag for the tdb CLI: Define event filters on the command line for easy grepping of events. Also added --verbose flag for troubleshooting filters.

  • tdb merge for tdb CLI. This operation is used to merge multipled tdbs into a single tdb.

  • Added a brew package for OS X.

  • Added installation instructions for FreeBSD.

Bugfixes

  • Make opening single-file tdbs thread-safe.

  • Fix handling of empty values in tdb_cons_append.

  • Fix handling of disk full situations in tdb_cons_append.
