registerSchemas

public void registerSchemas(SchemaConfig schemaConfig,
 org.apache.calcite.schema.SchemaPlus parent)
                     throws IOException

Historical note. This method used to eagerly register schemas for every enabled storage plugin instance, an operation that is expensive at best and unreliable in the presence of unresponsive storage plugins at worst. Now the schemas under the root are registered lazily by DynamicRootSchema.

Parameters:

schemaConfig - Configuration for schema objects.

parent - Reference to parent schema.

Throws:

IOException
