# The test is to run IS.TABLES query using two mode of reading
|
|
# dynamic table statistics.
|
|
#
|
|
# Case 1. Using IS.TABLES query definition that joins with
|
|
# mysql.tables.
|
|
#
|
|
# Case 2. Using IS.TABLES query definition that invokes UDF
|
|
# that read stats.
|
|
#
|
|
# Approach 2) deals with opening the table while query execution for
|
|
# non-InnoDB tables. And for InnoDB tables, the UDF's do not do
|
|
# complete open_table() and invoke new handlerton API,
|
|
# handlerton::get_table_statistics().
