> At present the Scan API supports only table level time range. We have
> specific use cases that will benefit from per column family time range. (See
> background discussion at
> https://mail-archives.apache.org/mod_mbox/hbase-user/201508.mbox/%3ccaa4mzom00ef5eoxstk0hetxeby8mqss61gbvgttgpaspmhq...@mail.gmail.com%3E)
> There are a couple of choices that would be good to validate. First - how to
> update the Scan API to support family and table level updates. One proposal
> would be to add Scan.setTimeRange(byte family, long minTime, long maxTime),
> then store it in a Map<byte[], TimeRange>. When executing the scan, if a
> family has a specified TimeRange, then use it, otherwise fall back to using
> the table level TimeRange. Clients using the new API against old region
> servers would not get the families correctly filterd. Old clients sending
> scans to new region servers would work correctly.
> The other question is how to get StoreFileScanner.shouldUseScanner to match
> up the proper family and time range. It has the Scan available but doesn't
> currently have available which family it is a part of. One option would be
> to try to pass down the column family in each constructor path. Another
> would be to instead alter shouldUseScanner to pass down the specific
> TimeRange to use (similar to how it currently passes down the columns to use
> which also appears to be a workaround for not having the family available).
