Related dev. issue(s): tarantool/tarantool#3389
Parent doc. issue: #4012

Product: Tarantool
Since: 3.0
Root document:

SME: @ nshy

Details

The parameter sets the number of threads used to sort keys of secondary
indexes on loading memtx database. The parameter cannot be changed
dynamically (as it does not make sense).

Maximum value is 256, minimum is 1. Default is to use all available cores.

Usage example:

box.cfg{memtx_sort_threads=4}

Requested by @ nshy in tarantool/tarantool@4f617b7.

Note that we still support OMP_NUM_THREADS environment variable, just for backward compatibility.
