- Code cleanu.
- Make MWL#90 code require @@optimizer_switch='semijoin=on'
- Update test results with the above
- Fork subselect_mat.test - we want to check both semi-join materialization,
which now has broader scope and non-semijoin materialization.
- More testcases
- Let add_ft_key() set keyuse->usable
mysql-test/r/table_elim.result:
MWL#17: Table elimination
- More testcases
mysql-test/t/table_elim.test:
MWL#17: Table elimination
- More testcases
sql/sql_select.cc:
MWL#17: Table elimination
- Let add_ft_key() set keyuse->usable
- Move eliminate_tables() to before constant table detection.
- First code for benchmark
sql-bench/test-table-elimination.sh:
MWL#17: Table elimination
- sql-bench "Benchmark", incomplete
sql/sql_select.cc:
MWL#17: Table elimination
- Move eliminate_tables() to before constant table detection, this will allow
to spare const table reads (at a cost of not being able to take advantage of
tables that are constant because they have no records, but this case is of
lesser importance)
