# Tests for DS-MRR over clustered primary key. The only engine that supports
# this is InnoDB/XtraDB.
#
# Basic idea about testing
# - DS-MRR/CPK works only with BKA
# - Should also test index condition pushdown
# - Should also test whatever uses RANGE_SEQ_IF::skip_record() for filtering
# - Also test access using prefix of primary key
#
# - Forget about cost model, BKA's multi_range_read_info() call passes 10 for
# #rows, the call is there at all only for applicability check
