+ +### December 18, 2025 + +
+`molt` 1.3.4 is [available](#installation): + +- Deprecated `data-load-and-replication`, `replication-only`, and `failback` modes in Fetch. Replication should now be performed separately with Replicator. Refer to the [MOLT Replicator]({% link molt/molt-replicator.md %}) documentation. +- Oracle-compatible MacOS builds are now available for arm64 and amd64. Refer to [Installation](#installation). +- Fixed a bug where the `--filter-path` flag for MOLT Fetch was hidden. `--filter-path` is now present for selective data movement in MOLT Fetch. +- MOLT Fetch now logs a warning when `--schema-filter` is used with MySQL sources, which do not support schemas. +- Fixed a character escaping bug where MOLT Verify was incorrectly reporting mismatching rows for JSON data in MySQL. +- Added better edge case handling for cleaning up the target database after `IMPORT` runs so that a fresh connection is opened, which mitigates against stale or already broken long-lived connections. +- Added better logging to handle the case where the recreation of a connection fails during a retry. +- Removed fixup mode, live verify mode, and continuous verify mode from MOLT Verify, including the `--continuous` and `--continuous-pause-between-runs` flags. +- Fixed a bug in retry logic to cleanly exit (without hanging) when the context is canceled and report the proper error. +
+ +
+`replicator` 1.2.0 is [available](#installation): + +- Updated metric names and descriptions and updated the dashboard to reflect these changes. Major metric name updates are as follows: + + - `mutations_{received,success,error}_count` -> `acceptor_mutations_total{type="received|success|error"}` + - `source_lag_seconds_histogram` -> `core_source_lag_seconds` + - `target_lag_seconds_histogram` -> `target_apply_transaction_lag_seconds` + - `target_apply_queue_depth` -> `target_apply_queue_size` + - `commit_to_stage_lag_seconds` -> `stage_commit_lag_seconds` + - `apply_mutation_age_seconds` -> `target_apply_mutation_age_seconds` + - `target_mutations_sent_to_apply_queue_count` -> `target_mutations_sent_to_apply_queue` + - `checkpoint_proposed_going_backwards_errors` -> `checkpoint_proposed_going_backwards_errors_total` + - Oracle LogMiner metrics are now prefixed with `oraclelogminer_` (including `oraclecheckpoint` metrics) + + For the rest of the metric name and description changes, run `curl http://localhost:{port}/_/varz` while running `replicator` with the `--metricsAddr` flag set. +- `RAW16` stored `UUID`s on Oracle can now be replicated into CockroachDB `UUID` columns when doing Oracle Log Miner source replication. +- Fixed a bug where Oracle timestamp parsing could use the wrong DST offset, resulting in incorrect UTC times for certain dates. +- Fixed observability for redo log parsing buckets so that the correct buckets and minimum durations are shown. Previously, the default for Prometheus buckets were too large, leading to incorrect redo log parsing time. +- Updated the Replicator sentinel table name to `REPLICATOR_SENTINEL` for Oracle LogMiner operation (Oracle source replication) to address a compatibility issue with JDBC drivers calling `getIndexInfo` on tables with leading underscores. +- Added metrics for the number of mutations sent to the apply queue from the `pglogical` frontend. +
+ +### October 24, 2025 + +
`molt` 1.3.2 is [available](#installation): - MOLT Fetch replication modes are deprecated in favor of a separate replication workflow using `replicator`. For details, refer to [MOLT Replicator]({% link molt/molt-replicator.md %}). - Added retry logic to the export phase for CockroachDB and PostgreSQL sources to handle transient errors while maintaining a consistent snapshot point. Not currently supported for Oracle or MySQL sources. - Added `--export-retry-max-attempts` and `--export-retry-max-duration` flags to control retry behavior for source query exports. +
+
`replicator` 1.1.3 is [available](#installation): - Added `commit_to_stage_lag_seconds` Prometheus histogram metric to track the distribution of source CockroachDB to staged data times. - Added `core_parallelism_utilization_percent` gauge to track parallelism utilization and identify when the system is nearing parallelism limits, and should be sized up. - Added `core_flush_count` metric to track the number of flushed batches in the applier flow and the reason for each flush. +
