tindex_id for each partition to the primary table's tindex_id. For partitioned tables, when Raft logs are parsed, the corresponding primary table's tindex_id can be located via the partition's tindex_id, thereby obtaining the table schema required for Raft log parsing by querying the sys.logservice_dd_tables table.Field Name | Type | Description |
sid | bigint unsigned | Stores the identifier for logservice. |
tindex_id | int unsigned | The ID for each partition. |
parent_tindex_id | int unsigned | The tindex id of the primary table corresponding to the current partition. |
