Detailed Description

A set of parameters for Kinetica.createMaterializedView.

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

Constructor & Destructor Documentation

◆ CreateMaterializedViewRequest() [1/2]

kinetica.CreateMaterializedViewRequest.CreateMaterializedViewRequest ( )

inline

Constructs a CreateMaterializedViewRequest object with default parameters.

Definition at line 376 of file CreateMaterializedView.cs.

◆ CreateMaterializedViewRequest() [2/2]

kinetica.CreateMaterializedViewRequest.CreateMaterializedViewRequest	(	string	table_name,
		IDictionary< string, string >	options = `null`
	)

inline

Constructs a CreateMaterializedViewRequest object with the specified parameters.

Parameters

table_name 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.

options

Optional parameters.

COLLECTION_NAME: [DEPRECATED–please specify the containing schema for the materialized view as part of table_name and use Kinetica.createSchema 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.
EXECUTE_AS: User name to use to run the refresh job
BUILD_MATERIALIZED_VIEW_POLICY: Sets startup materialized view rebuild scheme. Supported values:
- ALWAYS: Rebuild as many materialized views as possible before accepting requests.
- LAZY: Rebuild the necessary materialized views at start, and load the remainder lazily.
- ON_DEMAND: Rebuild materialized views as requests use them.
- SYSTEM: Rebuild materialized views using the system-configured default.
The default value is SYSTEM.
PERSIST: If TRUE, then the materialized view specified in table_name 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. Supported values:
- TRUE
- FALSE
The default value is FALSE.
REFRESH_SPAN: Sets the future time-offset(in seconds) at which periodic refresh stops
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'.
REFRESH_METHOD: Method by which the join can be refreshed when the data in underlying member tables have changed. Supported values:
- MANUAL: Refresh only occurs when manually requested by calling Kinetica.alterTable with an 'action' of 'refresh'
- ON_QUERY: Refresh any time the view is queried.
- 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.
- PERIODIC: Refresh table periodically at rate specified by REFRESH_PERIOD
The default value is MANUAL.
REFRESH_PERIOD: When REFRESH_METHOD is PERIODIC, specifies the period in seconds at which refresh occurs
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'.
TTL: Sets the TTL of the table specified in table_name .

The default value is an empty Dictionary.
