mem_limit
Indexing RAM usage limit. Optional, default is 128M.
Enforced memory usage limit that the indexer
will not go above. Can be specified in bytes, or kilobytes
(using K postfix), or megabytes (using M postfix); see the example.
This limit will be automatically raised if set to extremely low value
causing I/O buffers to be less than 8 KB; the exact lower bound
for that depends on the indexed data size. If the buffers are
less than 256 KB, a warning will be produced.
Maximum possible limit is 2047M. Too low values can hurt
indexing speed, but 256M to 1024M should be enough for most
if not all datasets. Setting this value too high can cause
SQL server timeouts. During the document collection phase,
there will be periods when the memory buffer is partially
sorted and no communication with the database is performed;
and the database server can timeout. You can resolve that
either by raising timeouts on SQL server side or by lowering
mem_limit.
Example:
mem_limit = 256M
## mem_limit = 262144K # same, but in KB
## mem_limit = 268435456 # same, but in bytes
