Usage

From source file:org.apache.hadoop.hbase.replication.regionserver.SerialReplicationChecker.java

public boolean canPush(Entry entry, Cell firstCellInEdit) throws IOException {
    String encodedNameAsString = Bytes.toString(entry.getKey().getEncodedRegionName());
    long seqId = entry.getKey().getSequenceId();
    Long canReplicateUnderSeqId = canPushUnder.getIfPresent(encodedNameAsString);
    if (canReplicateUnderSeqId != null) {
        if (seqId < canReplicateUnderSeqId.longValue()) {
            LOG.trace("{} is before the end barrier {}, pass", entry, canReplicateUnderSeqId);
            return true;
        }/*from   www  .  ja va 2  s. c om*/
        LOG.debug("{} is beyond the previous end barrier {}, remove from cache", entry, canReplicateUnderSeqId);
        // we are already beyond the last safe point, remove
        canPushUnder.invalidate(encodedNameAsString);
    }
    // This is for the case where the region is currently opened on us, if the sequence id is
    // continuous then we are safe to replicate. If there is a breakpoint, then maybe the region
    // has been moved to another RS and then back, so we need to check the barrier.
    MutableLong previousPushedSeqId = pushed.getUnchecked(encodedNameAsString);
    if (seqId == previousPushedSeqId.longValue() + 1) {
        LOG.trace("The sequence id for {} is continuous, pass", entry);
        previousPushedSeqId.increment();
        return true;
    }
    return canPush(entry, CellUtil.cloneRow(firstCellInEdit));
}
