| <div class="block">An asynchronous implementation of FSWAL. |
| <p> |
| Here 'waitingConsumePayloads' acts as the RingBuffer in FSHLog. |
| <p> |
| For append, we process it as follow: |
| <ol> |
| <li>In the caller thread(typically, in the rpc handler thread): |
| <ol> |
| <li>Insert the entry into 'waitingConsumePayloads'. Use ringbuffer sequence as txid.</li> |
| <li>Schedule the consumer task if needed. See <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#shouldScheduleConsumer--"><code>shouldScheduleConsumer()</code></a> for more details. |
| </li> |
| </ol> |
| </li> |
| <li>In the consumer task(executed in a single threaded thread pool) |
| <ol> |
| <li>Poll the entry from <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#waitingConsumePayloads"><code>waitingConsumePayloads</code></a> and insert it into |
| <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#toWriteAppends"><code>toWriteAppends</code></a></li> |
| <li>Poll the entry from <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#toWriteAppends"><code>toWriteAppends</code></a>, append it to the AsyncWriter, and insert it into |
| <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#unackedAppends"><code>unackedAppends</code></a></li> |
| <li>If the buffered size reaches <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#batchSize"><code>batchSize</code></a>, or there is a sync request, then we call |
| sync on the AsyncWriter.</li> |
| <li>In the callback methods: |
| <ul> |
| <li>If succeeded, poll the entry from <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#unackedAppends"><code>unackedAppends</code></a> and drop it.</li> |
| <li>If failed, add all the entries in <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#unackedAppends"><code>unackedAppends</code></a> back to <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#toWriteAppends"><code>toWriteAppends</code></a> and |
| wait for writing them again.</li> |
| </ul> |
| </li> |
| </ol> |
| </li> |
| </ol> |
| For sync, the processing stages are almost same. And different from FSHLog, we will open a new |
| writer and rewrite unacked entries to the new writer and sync again if we hit a sync error. |
| <p> |
| Here we only describe the logic of doReplaceWriter. The main logic of rollWriter is same with |
| FSHLog.<br> |
| For a normal roll request(for example, we have reached the log roll size): |
| <ol> |
| <li>In the log roller thread, we will set <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#waitingRoll-int-"><code>waitingRoll(int)</code></a> to true and |
| <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#readyForRolling"><code>readyForRolling</code></a> to false, and then wait on <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#readyForRolling"><code>readyForRolling</code></a>(see |
| <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#waitForSafePoint--"><code>waitForSafePoint()</code></a>).</li> |
| <li>In the consumer thread, we will stop polling entries from <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#waitingConsumePayloads"><code>waitingConsumePayloads</code></a> if |
| <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#waitingRoll-int-"><code>waitingRoll(int)</code></a> is true, and also stop writing the entries in <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#toWriteAppends"><code>toWriteAppends</code></a> out. |
| </li> |
| <li>If there are unflush data in the writer, sync them.</li> |
| <li>When all out-going sync request is finished, i.e, the <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#unackedAppends"><code>unackedAppends</code></a> is empty, |
| signal the <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#readyForRollingCond"><code>readyForRollingCond</code></a>.</li> |
| <li>Back to the log roller thread, now we can confirm that there are no out-going entries, i.e., |
| we reach a safe point. So it is safe to replace old writer with new writer now.</li> |
| <li>Set <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#writerBroken-int-"><code>writerBroken(int)</code></a> and <a href="../../../../../../org/apache/hadoop/hbase/regionserver/wal/AsyncFSWAL.html#waitingRoll-int-"><code>waitingRoll(int)</code></a> to false.</li> |
| <li>Schedule the consumer task.</li> |
| <li>Schedule a background task to close the old writer.</li> |
| </ol> |
| For a broken writer roll request, the only difference is that we can bypass the wait for safe |
| point stage.</div> |
