# Tests for the performance schema
#

# See comments in include/table_aggregate_setup.inc
#
# Notes about the optimizer and query plans:
# The following statement
#   SELECT * from t1 where b=5;
# can be executed either:
# - by using the index "index_b" on column b
# - by using a full table scan and the where clause.
# Which plan is used can be unpredictable.
# To ensure that the index is really used,
# so that table io against the index is measured,
# the payload in this test uses:
#   SELECT * from t1 force index(index_b) where b=5;
# 

# Display the current setup used

select * from performance_schema.setup_actors
  order by USER, HOST, ROLE;

select * from performance_schema.setup_objects
  order by object_type, object_schema, object_name;

select * from performance_schema.setup_consumers;
