Remove usage of deprecated variable storage_engine. It was deprecated in 5.5 but it never issued a deprecation warning. Make it issue a warning in 10.5.1. Replaced with default_storage_engine.

# 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
|
|
