Release notes¶

Version 2.5.1, 23 November 2017¶

JSON queries on HTTP API protocol. Supported search, insert, update, delete, replace operations. Data manipulation commands can be also bulked, also there are some limitations currently as MVA and JSON attributes can’t be used for inserts, replaces or updates.
RELOAD INDEXES command
FLUSH LOGS command
SHOW THREADS can show progress of optimize, rotation or flushes.
GROUP N BY work correctly with MVA attributes
blackhole agents are run on separate thread to not affect master query anymore
implemented reference count on indexes, to avoid stalls caused by rotations and high load
SHA1 hashing implemented, not exposed yet externally
fixes for compiling on FreeBSD, macOS and Alpine

OR operator in WHERE clause between attribute filters
Maintenance mode ( SET MAINTENANCE=1)
CALL KEYWORDS available on distributed indexes
Grouping in UTC
query_log_mode for custom log files permissions
Field weights can be zero or negative
max_query_time can now affect full-scans
added net_wait_tm, net_throttle_accept net_throttle_action and net_throttle_accept net_throttle_action for network thread fine tuning (in case of workers=thread_pool)
COUNT DISTINCT works with facet searches
IN can be used with JSON float arrays
multi-query optimization is not broken anymore by integer/float expressions
SHOW META shows a multiplier row when multi-query optimization is used

Manticore Search is built using cmake and the minimum gcc version required for compiling is 4.7.2.

Default log folder is now /var/log/manticore/.

Default pid folder is now /var/run/manticore/.
