Supported to customize lock timeout
In this release, Groonga began to support customizing lock timeout.
In the previous versions, the value of lock timeout is defined as about 3 hours. You can't change the value without modifying source code.
Now you can customize this value as configure option (–with-lock-timeout) or CMake build flags (-DGRN_LOCK_TIMEOUT).
$ ./configure --with-lock-timeout=(TIMEOUT)
$ cmake -DGRN_LOCK_TIMEOUT=(TIMEOUT)
See Global configuration documentation about the value of lock timeout.
GRN_JA_SKIP_SAME_VALUE_PUT is enabled by default
In the Groonga 3.1.0 release, GRN_JA_SKIP_SAME_VALUE_PUT environment variable is introduced experimentally.
This environment variable controls whether skipping to update the same value. As it was experimentally introduced at that time, it was not enabled by default, but now it is enabled by default at last!
If there are many queries with updating by the same value, it may suppress increasing the size of database by this change.
See Release 3.1.2 2014/01/29 about detailed changes since 3.1.1.
