SchemaBuilder (DataStax Java Driver for Apache Cassandra

java.lang.Object
- com.datastax.driver.core.schemabuilder.SchemaBuilder

```
public final class SchemaBuilder
extends Object
```
Static methods to build a CQL3 DDL statement.
The provided builders perform very little validation of the built query. There is thus no guarantee that a built query is valid, and it is definitively possible to create invalid queries.
Note that it could be convenient to use an 'import static' to use the methods of this class.
