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). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
