  Bug #26527 LOAD DATA INFILE extremely slow with partitioned table
  mysql_load calls hander::start_bulk_insert(0) to prepare caches
  for big inserts. As ha_partition didn't allow these caches
  for underlaying tables, the inserts were much slower

    allow using caches for BIG inserts

# This is a BitKeeper patch.  What follows are the unified diffs for the
# set of deltas contained in the patch.  The rest of the patch, the part
# that BitKeeper cares about, is below these diffs.
