What is a consolidated data point validator?



consolidated validators consolidated validators

Consolidated data point validators test the validity of data given to dataPoints. If the value in a dataPoint does not pass a validation, then a datablock violation is thrown and it becomes violated. This validation process is done in the consolidated validation pipeline stage.

Below is an example of a NOT_NULL validator used within a schema dataPoint. It will check if the value of the BID dataPoint is not null. If the validator finds that the value of BID is null then a violation is thrown.

When a feed is processed by the schema, the validator will validate the data and will throw a violation if the data does not pass the validation process.

NOTE: anywhere where {} with empty "{}" brackets appear, assume that config is optional and can be ignored in the majority of cases. The same applies where no element is shown in configuration.
