Create Kx Dataview

finspace_create_kx_dataview R Documentation

Creates a snapshot of kdb database with tiered storage capabilities and a pre-warmed cache, ready for mounting on kdb clusters

Description

Creates a snapshot of kdb database with tiered storage capabilities and a pre-warmed cache, ready for mounting on kdb clusters. Dataviews are only available for clusters running on a scaling group. They are not supported on dedicated clusters.

Usage

finspace_create_kx_dataview(environmentId, databaseName, dataviewName,
  azMode, availabilityZoneId, changesetId, segmentConfigurations,
  autoUpdate, readWrite, description, tags, clientToken)

Arguments

environmentId

[required] A unique identifier for the kdb environment, where you want to create the dataview.

databaseName

[required] The name of the database where you want to create a dataview.

dataviewName

[required] A unique identifier for the dataview.

azMode

[required] The number of availability zones you want to assign per volume. Currently, FinSpace only supports SINGLE for volumes. This places dataview in a single AZ.

availabilityZoneId

The identifier of the availability zones.

changesetId

A unique identifier of the changeset that you want to use to ingest data.

segmentConfigurations

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.

autoUpdate

The option to specify whether you want to apply all the future additions and corrections automatically to the dataview, when you ingest new changesets. The default value is false.

readWrite

The option to specify whether you want to make the dataview writable to perform database maintenance. The following are some considerations related to writable dataviews.

  • You cannot create partial writable dataviews. When you create writeable dataviews you must provide the entire database path.

  • You cannot perform updates on a writeable dataview. Hence, autoUpdate must be set as False if readWrite is True for a dataview.

  • You must also use a unique volume for creating a writeable dataview. So, if you choose a volume that is already in use by another dataview, the dataview creation fails.

  • Once you create a dataview as writeable, you cannot change it to read-only. So, you cannot update the readWrite parameter later.

description

A description of the dataview.

tags

A list of key-value pairs to label the dataview. You can add up to 50 tags to a dataview.

clientToken

[required] A token that ensures idempotency. This token expires in 10 minutes.

Value

A list with the following syntax: 

list(
  dataviewName = "string",
  databaseName = "string",
  environmentId = "string",
  azMode = "SINGLE"|"MULTI",
  availabilityZoneId = "string",
  changesetId = "string",
  segmentConfigurations = list(
    list(
      dbPaths = list(
        "string"
      ),
      volumeName = "string",
      onDemand = TRUE|FALSE
    )
  ),
  description = "string",
  autoUpdate = TRUE|FALSE,
  readWrite = TRUE|FALSE,
  createdTimestamp = as.POSIXct(
    "2015-01-01"
  ),
  lastModifiedTimestamp = as.POSIXct(
    "2015-01-01"
  ),
  status = "CREATING"|"ACTIVE"|"UPDATING"|"FAILED"|"DELETING"
)
