Subbu M Iyer commented on HBASE-3488:
-------------------------------------
Ted/Jonathan:
Just want to better understand the solution we are proposing so that I can work
on this issue.
1. We shall create a CellCounter that kind of extends the RowCounter and
provides additional functionality to count all the versions of all rows instead
of just the latest version?
2. From Jonathan's comment we also want "stats like # of rows, total # of
columns / avg columns per row, total # of versions / avg versions per column /
avg versions per row, etc" ?
Please let me know.
> Allow RowCounter to retrieve multiple versions of rows

> URL: https://issues.apache.org/jira/browse/HBASE-3488
> Project: HBase
> Issue Type: Bug
> Components: util
> Affects Versions: 0.90.0
> Reporter: Ted Yu
> Fix For: 0.92.0
>
>
> Currently RowCounter only retrieves latest version for each row.
> Some applications would store multiple versions for the same row.
> RowCounter should accept a new parameter for the number of versions to return.
> Scan object would be configured with version parameter (for scan.maxVersions).
> Then the following API should be called:
> {code}
> public KeyValue[] raw() {
> {code}
