----------------------------------------

             Summary: Rework disctributed configuration flow
                 Key: IGNITE-15404
                 URL: https://issues.apache.org/jira/browse/IGNITE-15404
             Project: Ignite
          Issue Type: Improvement
            Reporter: Alexander Lapin


Based on prototyping carried out within IGNITE-15374 it's requited to rework distributed configuration flow processing:
 # Use configuration registry instead of meta storage manager.
 ## Use configuration manager for internal configuration processing. Blocked by IGNITE-15047
 ## Use configuration manager in order to retrieve distributed up-to-date values.
 ## Use configuration listeners instead of meta storage watches.
 # Favor one-step table creation (calculate assignments and inner schema together with initial table configuration update).

Please pay attention that during prototyping plenty of bugs were found that should be fixed during refactoring. To name some:
 # Columns validation is skipped if column was added or removed during alterTable() See onConfigurationChanged() for more details.
{code:java}
if (!newTbl.columns().namedListKeys().equals(oldTbl.columns().namedListKeys()))
    return true;
{code}

 # table identified ignores update counter
{code:java}
UUID tblId = new UUID(ctx.storageRevision(), 0L);
{code}
 

Of course in addition to fixing known issues we will introduce new bugs during refactoring.
