Example 1 with GetSequenceRequest

use of io.dingodb.store.row.cmd.store.GetSequenceRequest in project dingo by dingodb.

the class DefaultDingoRowStore method internalGetSequence.

private void internalGetSequence(final byte[] seqKey, final int step, final CompletableFuture<Sequence> future, final int retriesLeft, final Errors lastCause) {
    final Region region = this.pdClient.findRegionByKey(seqKey, ErrorsHelper.isInvalidEpoch(lastCause));
    final RegionEngine regionEngine = getRegionEngine(region.getId(), true);
    final RetryRunner retryRunner = retryCause -> internalGetSequence(seqKey, step, future, retriesLeft - 1, retryCause);
    final FailoverClosure<Sequence> closure = new FailoverClosureImpl<>(future, retriesLeft, retryRunner);
    if (regionEngine != null) {
        if (ensureOnValidEpoch(region, regionEngine, closure)) {
            getRawKVStore(regionEngine).getSequence(seqKey, step, closure);
        }
    } else {
        final GetSequenceRequest request = new GetSequenceRequest();
        request.setSeqKey(seqKey);
        request.setStep(step);
        request.setRegionId(region.getId());
        request.setRegionEpoch(region.getRegionEpoch());
        this.dingoRowStoreRpcService.callAsyncWithRpc(request, closure, lastCause);
