In 5.4.x, the datafeed attempts to get all fields from doc_values by default. It has a `_source` parameter which when enabled changes the strategy to instead try to get all fields from the source. This has been the most common issue users have been reporting as it means the datafeed will fail to fetch any text fields by default. This change uses the field capabilities API in order to automatically detect whether a field is aggregatable. It then extracts such fields from doc_values while the rest are taken from source. The change also adds validation to the start datafeed action so that if fields are missing mappings or the time field is not aggregatable we respond with an appropriate error. relates elastic/x-pack-elasticsearch#1649 Original commit: elastic/x-pack-elasticsearch@76e2cc6cb2 |
