use of io.dingodb.store.row.storage.BaseKVStoreClosure in project dingo by dingodb.

the class DefaultRegionKVService method handleGetRequest.

@Override

    final GetResponse response = new GetResponse();
    response.setRegionId(getRegionId());
    response.setRegionEpoch(getRegionEpoch());
    try {

        final byte[] key = KVParameterRequires.requireNonNull(request.getKey(), "get.key");
        this.rawKVStore.get(key, request.isReadOnlySafe(), new BaseKVStoreClosure() {

            @Override
