Hi, I'm developing monitoring tool in daemon plugin I'm tyring to access pfs table via low level interface not using sql. (see below) ------------------------------------------------------------------------ ------------- ..... tables.init_one_table(STRING_WITH_LEN("performance_schema"), STRING_WITH_LEN("events_statements_current"), "events_statements_current", TL_READ); bool result = open_and_lock_tables(ctx->thd, &tables, FALSE, MYSQL_LOCK_IGNORE_TIMEOUT); if (result) { sql_print_error("monm plugin error: Can't open the %s.%s table.",dbname,tblname); } ..... /* read routine */ ------------------------------------------------------------ In open_and_lock_table function, I hava a error. I found the reason of this error by debugging. In table_cache.cc, open_table_def() requires .frm file as a table definition. but above version 10.1.3, there is no frm file for pfs table as I know. right? Let me know a correct way to get data from pfs table not using sql.
