Examples with Shard com.amazonaws.services.dynamodbv2.model.Shard used on opensource projects

Example 6 with Shard

use of com.amazonaws.services.dynamodbv2.model.Shard in project camel by apache.

the class ShardList method atAfterSeq.

Shard atAfterSeq(String sequenceNumber, BigIntComparisons condition) {
    BigInteger atAfter = new BigInteger(sequenceNumber);
    List<Shard> sorted = new ArrayList<>();
    sorted.addAll(shards.values());
    Collections.sort(sorted, StartingSequenceNumberComparator.INSTANCE);
    for (Shard shard : sorted) {
        if (shard.getSequenceNumberRange().getEndingSequenceNumber() != null) {
            BigInteger end = new BigInteger(shard.getSequenceNumberRange().getEndingSequenceNumber());
            // essentially: after < end or after <= end
            if (condition.matches(atAfter, end)) {
                return shard;
            }
        }
    }
    if (shards.size() > 0) {
        return sorted.get(sorted.size() - 1);
    }
    throw new IllegalStateException("Unable to find a shard with appropriate sequence numbers for " + sequenceNumber + " in " + shards);
}
