Overview to managing schemas

You can use DDL statements such as CREATE SCHEMA, USE SCHEMA and DROP SCHEMA to manage schemas.

You must have admin privileges in HBase to run CREATE SCHEMA or DROP SCHEMA.

See the Apache Phoenix Grammar reference page for how you can use these DDL statements.

As you create physical tables, views, and indexes, you can associate them with a schema. If the schema already has namespace mapping enabled, the newly created objects automatically become part of the HBase namespace. The directory of the HBase namespace that maps to the Phoenix schema inherits the schema name. For example, if the schema name is store1, then the full path to the namespace is $hbase.rootdir/data/store1. See the "F.A.Q." section of Apache Phoenix Namespace Mapping for more information.
