public static final class FlightSql.CommandGetDbSchemas.Builder extends com.google.protobuf.GeneratedMessage.Builder<FlightSql.CommandGetDbSchemas.Builder> implements FlightSql.CommandGetDbSchemasOrBuilder

 Represents a request to retrieve the list of database schemas on a Flight SQL enabled backend.
 The definition of a database schema depends on vendor/implementation. It is usually a collection of tables.
 Used in the command member of FlightDescriptor for the following RPC calls:
 - GetSchema: return the Arrow schema of the query.
 - GetFlightInfo: execute the catalog metadata request.

 The returned Arrow schema will be:
 <
 catalog_name: utf8,
 db_schema_name: utf8 not null
 >
 The returned data should be ordered by catalog_name, then db_schema_name.
