> Time to time we see a case, when the open / aborted transaction count is high and often the aborted transactions come in continues ranges.
> When the transaction count goes high the serialization / deserialization to hive.txn.valid.txns conf gets slower and produces a large config value.
> Using ranges in the string representation can mitigate the issue somewhat.
