update_kx_dataview#

finspace.Client.update_kx_dataview(**kwargs)#

Updates the specified dataview. The dataviews get automatically updated when any new changesets are ingested. Each update of the dataview creates a new version, including changeset details and cache configurations

Request Syntax

response = client.update_kx_dataview(
    environmentId='string',
    databaseName='string',
    dataviewName='string',
    description='string',
    changesetId='string',
    segmentConfigurations=[
        {
            'dbPaths': [
                'string',
            ],
            'volumeName': 'string',
            'onDemand': True|False
        },
    ],
    clientToken='string'
)

Parameters:

environmentId (string) –
[REQUIRED]

A unique identifier for the kdb environment, where you want to update the dataview.
databaseName (string) –
[REQUIRED]

The name of the database.
dataviewName (string) –
[REQUIRED]

The name of the dataview that you want to update.
description (string) – The description for a dataview.
changesetId (string) – A unique identifier for the changeset.
segmentConfigurations (list) –
The configuration that contains the database path of the data that you want to place on each selected volume. Each segment must have a unique database path for each volume. If you do not explicitly specify any database path for a volume, they are accessible from the cluster through the default S3/object store segment.
- (dict) –
  
  The configuration that contains the database path of the data that you want to place on each selected volume. Each segment must have a unique database path for each volume. If you do not explicitly specify any database path for a volume, they are accessible from the cluster through the default S3/object store segment.
  - dbPaths (list) – [REQUIRED]
    
    The database path of the data that you want to place on each selected volume for the segment. Each segment must have a unique database path for each volume.
    - (string) –
  - volumeName (string) – [REQUIRED]
    
    The name of the volume where you want to add data.
  - onDemand (boolean) –
    
    Enables on-demand caching on the selected database path when a particular file or a column of the database is accessed. When on demand caching is True, dataviews perform minimal loading of files on the filesystem as needed. When it is set to False, everything is cached. The default value is False.
clientToken (string) –
[REQUIRED]

A token that ensures idempotency. This token expires in 10 minutes.

This field is autopopulated if not provided.

Return type:
