Types ¶
type CopContext ¶
type CopContext interface {
GetBase() *CopContextBase
IndexColumnOutputOffsets(idxID int64) []int
IndexInfo(idxID int64) *model.IndexInfo
}
CopContext contains the information that is needed when building a coprocessor request. It is unchanged after initialization.
func NewCopContext ¶
func NewCopContext( exprCtx exprctx.BuildContext, distSQLCtx *distsqlctx.DistSQLContext, pushDownFlags uint64, tblInfo *model.TableInfo, allIdxInfo []*model.IndexInfo, requestSource string, ) (CopContext, error)
NewCopContext creates a CopContext.
type CopContextBase ¶
type CopContextBase struct {
TableInfo *model.TableInfo
PrimaryKeyInfo *model.IndexInfo
ExprCtx exprctx.BuildContext
DistSQLCtx *distsqlctx.DistSQLContext
PushDownFlags uint64
RequestSource string
ColumnInfos []*model.ColumnInfo
FieldTypes []*types.FieldType
ExprColumnInfos []*expression.Column
HandleOutputOffsets []int
VirtualColumnsOutputOffsets []int
VirtualColumnsFieldTypes []*types.FieldType
}
CopContextBase contains common fields for CopContextSingleIndex and CopContextMultiIndex.
func NewCopContextBase ¶
func NewCopContextBase( exprCtx exprctx.BuildContext, distSQLCtx *distsqlctx.DistSQLContext, pushDownFlags uint64, tblInfo *model.TableInfo, idxCols []*model.IndexColumn, requestSource string, ) (*CopContextBase, error)
NewCopContextBase creates a CopContextBase.
type CopContextMultiIndex ¶
type CopContextMultiIndex struct {
*CopContextBase
// contains filtered or unexported fields
}
CopContextMultiIndex is the coprocessor context for multiple indexes.
func NewCopContextMultiIndex ¶
func NewCopContextMultiIndex( exprCtx exprctx.BuildContext, distSQLCtx *distsqlctx.DistSQLContext, pushDownFlags uint64, tblInfo *model.TableInfo, allIdxInfo []*model.IndexInfo, requestSource string, ) (*CopContextMultiIndex, error)
NewCopContextMultiIndex creates a CopContextMultiIndex.
func (*CopContextMultiIndex) GetBase ¶
func (c *CopContextMultiIndex) GetBase() *CopContextBase
GetBase implements the CopContext interface.
func (*CopContextMultiIndex) IndexColumnOutputOffsets ¶
func (c *CopContextMultiIndex) IndexColumnOutputOffsets(indexID int64) []int
IndexColumnOutputOffsets implements the CopContext interface.
type CopContextSingleIndex ¶
type CopContextSingleIndex struct {
*CopContextBase
// contains filtered or unexported fields
}
CopContextSingleIndex is the coprocessor context for single index.
func NewCopContextSingleIndex ¶
func NewCopContextSingleIndex( exprCtx exprctx.BuildContext, distSQLCtx *distsqlctx.DistSQLContext, pushDownFlags uint64, tblInfo *model.TableInfo, idxInfo *model.IndexInfo, requestSource string, ) (*CopContextSingleIndex, error)
NewCopContextSingleIndex creates a CopContextSingleIndex.
func (*CopContextSingleIndex) GetBase ¶
func (c *CopContextSingleIndex) GetBase() *CopContextBase
GetBase implements the CopContext interface.
func (*CopContextSingleIndex) IndexColumnOutputOffsets ¶
func (c *CopContextSingleIndex) IndexColumnOutputOffsets(_ int64) []int
IndexColumnOutputOffsets implements the CopContext interface.
