[jira] [Created] (CASSANDRA-9257) Schema Builder does not support multiple column add/drop/alter

[Oleksandr Petrov (JIRA)]

Oleksandr Petrov created CASSANDRA-9257:
-------------------------------------------

             Summary: Schema Builder does not support multiple column 
add/drop/alter 
                 Key: CASSANDRA-9257
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9257
             Project: Cassandra
          Issue Type: Improvement
          Components: Drivers (now out of tree)
            Reporter: Oleksandr Petrov


Right now, SchemaBuilder allows adding, altering or dropping only one column, 
for example:

```
SchemaBuilder.alterTable("ks", "DropColumn")
                .addColumn("b")
                .type(DataType.cint()
```

There's no way to say `addColumn` after that once again, so one has to create 
another statement.

I'd be glad to help out / contribute that one, if everyone generally agrees 
that this is a good addition to API.

This would be a great addition, and will help one of Clojure drivers to provide 
a smoother API, too. 

Thanks!
