Additionally i found that current main implementation differs from represented in PR, can someone recheck after me ? 
Benchmark [main]                      Mode  Cnt     Score     Error  Units
SqlBenchmark.selectAllSimple  thrpt   10  2300.348 ± 467.203  ops/s

Benchmark [pr-1537]                     Mode  Cnt     Score     Error  Units
SqlBenchmark.selectAllSimple  thrpt   10  2945.170 ± 576.279  ops/s

> Looks like integration IndexScanNode and RO transaction is missing.
> Let's fill this gap by propagating transaction timestamp to the 'scan' invocation in IndexScanNode.
