We would like to share with other nodes the value of ignore_msb_bits property used by the node. This is needed because CDC will operate on streams of changes. Each shard on each node will have its own stream that will be identified by a stream_id. Stream_id will be selected in such a way that using stream_id as partition key will locate partition identified by stream_id on a node and shard that the stream belongs to. To be able to generate such stream_id we need to know ignore_msb_bits property value for each node. IMPORTANT NOTE: At this point CDC does not support topology changes. It will work only on a stable cluster. Support for topology modifications will be added in later steps. Signed-off-by: Piotr Jastrzebski <piotr@scylladb.com>
