The settings in custom push profiles should be based on workload and the recommendations of your Teradata Customer Support Representative.
The following procedure shows how to use one of the following macros to create custom push profiles.
  • Update macro (TD_UPDATE_PUSHPROFILE). This macro uses the existing push profile name, the JSONPath of the operation that needs to be overwritten, and a JSON document containing the new values for the operation.
  • Overwrite macro (TD_OVERWRITE_PUSHPROFILE). This macro contains JSON that overwrites the entire push profile named in the macro.
Hive is used as an example. Use the same steps to create custom push profiles for Teradata and Presto.
  1. Create a custom push profile.
    Option Steps
    Using the update macro
    1. Copy the default push profile and rename it.

      In the example below, CompareOp in the custom push profile Hive_Custom1 is overwritten with a new JSON specification, which is ('default':false).
      EXECUTE TD_UPDATE_PUSHPROFILE(‘Hive_Custom1’, ‘$.ColOp[0].CompareOp’, new JSON(‘{default : false}’));
    Using the overwrite macro In the example below, the overwrite macro is used to overwrite an entire, existing custom push profile (Hive_Custom1) with a new JSON specification.
