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/daiguadaidai/tidb/perfschema"

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

func RegisterTable

func RegisterTable(tableName, sql string,
	tableFromMeta func(autoid.Allocator, *model.TableInfo) (table.Table, error))

RegisterTable registers a new table into TiDB.
