Problem:
When execute a sql query, FE will send a request to BE. The request contains tablets and their partitions' visible versions. BE need to obtains the tablet's rowsets in range [0, visible version]. But sometimes BE may had compacted visible version rowset with large version rowsets, so it can not return rowsets just in range [0, visible version]. Then BE will return error VERSION_ALREADY_MERGED -230.
