Detailed Description

A set of input parameters for const.

Initiates the process of creating a materialized view, reserving the view's name to prevent other views or tables from being created with that name.

For materialized view details and examples, see Materialized Views.

The response contains viewId, which is used to tag each subsequent operation (projection, union, aggregation, filter, or join) that will compose the view.

inline

Constructs a CreateMaterializedViewRequest object with the specified parameters.

Parameters

[in]	tableName_	Name of the table to be created that is the top-level table of the materialized view, in [schema_name.]table_name format, using standard name resolution rules and meeting table naming criteria.
[in]	options_	Optional parameters. gpudb::create_materialized_view_collection_name: [DEPRECATED–please specify the containing schema for the materialized view as part of tableName and use /create/schema to create the schema if non-existent] Name of a schema which is to contain the newly created view. If the schema provided is non-existent, it will be automatically created. gpudb::create_materialized_view_execute_as: User name to use to run the refresh job gpudb::create_materialized_view_persist: If true, then the materialized view specified in tableName will be persisted and will not expire unless a ttl is specified. If false, then the materialized view will be an in-memory table and will expire unless a ttl is specified otherwise. gpudb::create_materialized_view_true gpudb::create_materialized_view_false The default value is gpudb::create_materialized_view_false. gpudb::create_materialized_view_refresh_span: Sets the future time-offset(in seconds) at which periodic refresh stops gpudb::create_materialized_view_refresh_stop_time: When refresh_method is periodic, specifies the time at which a periodic refresh is stopped. Value is a datetime string with format 'YYYY-MM-DD HH:MM:SS'. gpudb::create_materialized_view_refresh_method: Method by which the join can be refreshed when the data in underlying member tables have changed. gpudb::create_materialized_view_manual: Refresh only occurs when manually requested by calling /alter/table with an 'action' of 'refresh' gpudb::create_materialized_view_on_query: Refresh any time the view is queried. gpudb::create_materialized_view_on_change: If possible, incrementally refresh (refresh just those records added) whenever an insert, update, delete or refresh of input table is done. A full refresh is done if an incremental refresh is not possible. gpudb::create_materialized_view_periodic: Refresh table periodically at rate specified by refresh_period The default value is gpudb::create_materialized_view_manual. gpudb::create_materialized_view_refresh_period: When refresh_method is periodic, specifies the period in seconds at which refresh occurs gpudb::create_materialized_view_refresh_start_time: When refresh_method is periodic, specifies the first time at which a refresh is to be done. Value is a datetime string with format 'YYYY-MM-DD HH:MM:SS'. gpudb::create_materialized_view_ttl: Sets the TTL of the table specified in tableName.
