Eugene Koifman commented on HIVE-16534:
---------------------------------------
bq. I do serialize the BitSet into a byte array before sending it over Thrift
interface. After receiving it I convert it back to BitSet since the bit
manipulation is convenient.
I meant in writeToString() - seems like that would make reading from string
much simper/efficient
You are right about the other points

> Currently in ValidReadTxnList, open transactions and aborted transactions are
> stored together in one array. That makes it impossible to extract just
> aborted transactions or open transactions.
> For ValidCompactorTxnList this is fine, since we only store aborted
> transactions but no open transactions.
