Wei Zheng commented on HIVE-13249:
----------------------------------
OK, one more concern, is it a good idea to have performTimeOuts() and
countOpenTxns() share the same check intervals? We may want to do it more
frequent for the latter one.
> Hard upper bound on number of open transactions

> Issue Type: Improvement
> Components: Transactions
> Affects Versions: 2.0.0

> We need to have a safeguard by adding an upper bound for open transactions to
> avoid huge number of open-transaction requests, usually due to improper
> configuration of clients such as Storm.
> Once that limit is reached, clients will start failing.
