> Ignite should support {{DROP COLUMN}} operation for {{ALTER TABLE}} command.
> Design considerations:
> 1) Drop should only be possible on binary types without schema (see 
> IGNITE-6611). Probably we will need a new option for {{CREATE TABLE}} command
> 2) Drop should not block other operations for a long time. We should 
> synchronously block the table, change meta, then release the lock and let 
> operations continue.
> 3) Actual data remove should be performed asynchronously in the same way we 
> create index. During this time we should not allow any other modifications to 
> the table
> 4) Be careful with node stop - we do not want to wait for years for this 
> command to complete.
