> Use ranges in ValidReadTxnList serialization
> --------------------------------------------

> Key: HIVE-23819
> URL: https://issues.apache.org/jira/browse/HIVE-23819
> Project: Hive
> Issue Type: Improvement
> Reporter: Peter Varga
> Assignee: Peter Varga
> Priority: Major
> Labels: pull-request-available
> Time Spent: 50m
> Remaining Estimate: 0h
>
> 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.
