Bugs Fixed in this Release:

    • Streaming sender-side failures were not propagated to the receiving side. #1743
    • Streaming many column families at the same time generated many small sstables on the receiving side. #3065
    • Streaming may overload a new node which fails to boot as a result. #3258, 3311
    • CQL prepared statements are now properly evicted, thus preventing server OOM when preparing many unique statements. #2747
    • Authentication requests might return expired permission from cache. #2590
    • Dropping a keyspace with a User Defined Type(UDT) resulted in an error: “InvalidRequest: Error from server: code=2200 [Invalid query] message=”Unknown type…”. #3068
    • Scylla aborted with an “Assertion `end >= _stream_position’ failed” exception. This occurred when querying a partition with no clustering ranges (happened on a counter table with no live rows) which also didn’t have static columns. #3304
    • In some rare cases when one or more nodes were down, a Scylla gossip bug caused Scylla to exit with a segmentation fault. #3299
    • In some cases, a removed node (removed using nodetool) failed to bootstrap. #3331
    • A TLS session can be closed while an IO continuation is still in flight, causing a “system:32, Broken pipe” error #3358
    • In a case where gossip information is not available yet, for example during a cluster init, nodetool gossipinfo may fail with NullPointerException. #3330
    • sstableloader does not support User Defined Type(UDT). scylla-tools-java #57
    • sstableloader cannot bind prepared statement for a table using “date” type. scylla-tools-java #59
