Example 5 with BigInteger

use of java.math.BigInteger in project storm by apache.

the class TransactionalSpoutCoordinator method sync.

private void sync() {
    // note that sometimes the tuples active may be less than max_spout_pending, e.g.
    // max_spout_pending = 3
    // tx 1, 2, 3 active, tx 2 is acked. there won't be a commit for tx 2 (because tx 1 isn't committed yet),
    // and there won't be a batch for tx 4 because there's max_spout_pending tx active
