---------------------------------------
Summary: Initiate DDL operation through custom discovery message
Key: IGNITE-4633
URL: https://issues.apache.org/jira/browse/IGNITE-4633
Project: Ignite
Issue Type: Sub-task
Components: SQL
Reporter: Vladimir Ozerov
Fix For: 2.0
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.
