type DecodedKey ¶
type DecodedKey struct {
DbName string `json:"db_name,omitempty"`
TableName string `json:"table_name,omitempty"`
PartitionName string `json:"partition_name,omitempty"`
HandleType HandleType `json:"handle_type,omitempty"`
HandleValue string `json:"handle_value,omitempty"`

DbID int64 `json:"db_id,omitempty"`
TableID int64 `json:"table_id"`
PartitionID int64 `json:"partition_id,omitempty"`
IndexID int64 `json:"index_id,omitempty"`
IsPartitionHandle bool `json:"partition_handle,omitempty"`
}
DecodedKey is a struct contains detailed information about a key, its json form should be used to fill KEY_INFO field in `DEADLOCKS` and `DATA_LOCK_WAITS`
func DecodeKey ¶
func DecodeKey(key []byte, infoschema infoschema.InfoSchema) (DecodedKey, error)
DecodeKey decodes `key` (either a Record key or an Index key) into `DecodedKey`, which is used to fill KEY_INFO field in `DEADLOCKS` and `DATA_LOCK_WAITS`
type HandleType ¶
