Without tweaking interface, there was no way to adjust estimated partitions on flush. For example, when segregating a memtable for TWCS, all produced sstables would have an estimation equal to the memtable size, even though each only contains a subset of it, which leads to a significant increase in memory consumption for bloom filters. Subsequent work will use this interface to perform the adjustment. Signed-off-by: Raphael S. Carvalho <raphaelsc@scylladb.com> Message-Id: <20211103141600.65806-1-raphaelsc@scylladb.com>
