Meta Service Configuration
This page lists Meta Service configuration options added in 4.1.5 and does not yet cover all options. Meta Service uses doris_cloud.conf; these options do not belong in the FE's fe.conf or the BE's be.conf.
Transaction management
enable_get_prepare_txn_by_coordinator_by_running_key
| Item | Value |
|---|---|
| Type | Boolean |
| Default | true |
| Changeable at runtime | Yes |
| Version | Added in 4.1.5 |
Controls how Meta Service scans for prepared transactions belonging to a coordinator. By default, it scans the running-transaction index first, then retrieves the corresponding transaction information, avoiding a scan of all transaction records. Set it to false to scan transaction information records directly. Both approaches use the same transaction selection criteria and return the same results. Keep the default unless you need to change the scan strategy.
To set the option explicitly, add the following to Meta Service's doris_cloud.conf:
enable_get_prepare_txn_by_coordinator_by_running_key = true
