Functions

func Init

func Init()

Init register the PERFORMANCE_SCHEMA virtual tables. It should be init(), and the ideal usage should be:

import _ "github.com/pingcap/tidb/perfschema"

This function depends on plan/core.init(), which initialize the expression.EvalSimpleAst function. The initialize order is a problem if init() is used as the function name.

func IsPredefinedTable

func IsPredefinedTable(tableName string) bool

IsPredefinedTable judges whether this table is predefined.
