The ME format has been introduced in Cassandra 3.11.11:11952fae77/src/java/org/apache/cassandra/io/sstable/format/big/BigFormat.java (L123)d84c6e9810It adds originating host id to sstable metadata in support of fixing loss of commit log data when moving sstables between nodes: https://issues.apache.org/jira/browse/CASSANDRA-16619 In Scylla: * The supported way to ingest sstables is via upload/, where stored commit log replay position should be disregarded (but see https://github.com/scylladb/scylla/issues/10080). * A later commit in this series implements originating host id validation for native ME sstables.
