Changing the limit for retrieving distinct values for data segmentation (IBM Knowledge Catalog)

You can change the maximum number of distinct values that can be retrieved for segmenting column data when users create dynamic views in projects.

By default, a maximum of 100 distinct values are retrieved for a column that a user selects for segmenting a data asset by column values. Depending on your business requirements, this number might be too low. You can change the limit for all projects in the deployment by running one of the following commands:

• Change the limit by updating the IBM Knowledge Catalog custom resource (wkc-cr):

  oc patch wkc wkc-cr -n ${PROJECT_CPD_INST_OPERATORS} --type=merge -p '{"spec":{"wkc_data_quality_retrieve_distinct_values_max_count":"200"}}'
  

• Change the limit by setting an environment variable:

  oc set env deployment/wkc-data-rules RETRIEVE_DISTINCT_VALUES_MAX_COUNT=200
