Hi, I want to propose merging the patch in CASSANDRA-18941 to 4.0 and up to trunk and hope we are all OK with it.
In CASSANDRA-18941, I am adding the capability to produce size-bounded SSTables in CQLSSTableWriter for sorted data. It can greatly benefit Cassandra Analytics (https://github.com/apache/cassandra-analytics) for bulk writing SSTables, since it avoids buffering and sorting on flush, given the data source is sorted already in the bulk write process. Cassandra Analytics supports Cassandra 4.0 and depends on the cassandra-all 4.0.x library. Therefore, we are mostly interested in using the new capability in 4.0. CQLSSTableWriter is only used in offline tools and never in the code path of Cassandra server. Any objections to merging the patch to 4.0 and up to trunk? - Yifan
