Examples with NotLeaderException org.apache.kafka.raft.errors.NotLeaderException used on opensource projects

Example 1 with NotLeaderException

use of org.apache.kafka.raft.errors.NotLeaderException in project kafka by apache.

the class KafkaRaftClient method append.

private long append(int epoch, List<T> records, boolean isAtomic) {
    LeaderState<T> leaderState = quorum.<T>maybeLeaderState().orElseThrow(() -> new NotLeaderException("Append failed because the replication is not the current leader"));
    BatchAccumulator<T> accumulator = leaderState.accumulator();
    boolean isFirstAppend = accumulator.isEmpty();
    final long offset;
    if (isAtomic) {
        offset = accumulator.appendAtomic(epoch, records);
    } else {
        offset = accumulator.append(epoch, records);
    }
    // there are no additional appends.
    if (isFirstAppend || accumulator.needsDrain(time.milliseconds())) {
        wakeup();
    }
    return offset;
}

Example 2 with NotLeaderException

use of org.apache.kafka.raft.errors.NotLeaderException in project kafka by apache.

the class BatchAccumulator method append.

            batch.appendRecord(record, serializationCache);
            nextOffset += 1;
