Log Context

Log “[{}] Removing intervening records after reverting model: deleting results after [{}]” classname is TransportRevertModelSnapshotAction.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

        // If we need to delete buckets that occurred after the snapshot; we
        // wrap the listener with one that invokes the OldDataRemover on
        // acknowledged responses
        return ActionListener.wrap(response -> {
            Date deleteAfter = modelSnapshot.getLatestResultTimeStamp() == null ? new Date(0) : modelSnapshot.getLatestResultTimeStamp();
            logger.info("[{}] Removing intervening records after reverting model: deleting results after [{}]"; jobId; deleteAfter);

            JobDataDeleter dataDeleter = new JobDataDeleter(client; jobId);
            dataDeleter.deleteResultsFromTime(deleteAfter.getTime() + 1; listener.delegateFailure((l; r) -> l.onResponse(response)));
        }; listener::onFailure);
    }
