| `waiting_txn_fingerprint_id` | `BYTES NOT NULL` | The ID of the waiting transaction fingerprint. To surface historical information about the transactions that caused the [contention]({% link {{ page.version.version }}/performance-best-practices-overview.md %}#transaction-contention), you can join this column into the [`statement_statistics`]({% link {{ page.version.version }}/crdb-internal.md %}#statement_statistics) and [`transaction_statistics`]({% link {{ page.version.version }}/crdb-internal.md %}#transaction_statistics) tables. | ||
| `waiting_stmt_id` | `STRING NOT NULL` | The statement id of the transaction that was waiting (unique for each statement execution). | ||
| `waiting_stmt_fingerprint_id` | `BYTES NOT NULL` | The fingerprint of the statement that was waiting (same for each statement with the same SQL, application name, etc.). |
