Vladimir Ozerov updated IGNITE-4633:
------------------------------------
Description:
Design considerations:
1) Create generic DDL custom discovery message pair - {{INIT}} and {{ACK}}
messages - which will hold concrete DDL commands:
2) {{INIT}} message goes through the ring and:
- Collect IDs of all participating nodes;
- Perform some fast preliminary checks if necessary;
- Collect errors if needed;
3) If at least one error occur - throw exception on a originator node;
4) If all is OK - send {{ACK}} message.
5) {{ACK}} message initiates actual operation. No-op at the moment.
6) Finally, originator node is provided with the list of participating nodes.
