{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Return missing feature metadata in response","articleBody":"There is currently no simple mechanism for differentiating between missing and null features. A missing feature would be one where the feature creation pipeline for the corresponding timestamp has not been run yet, thus feature retrieval yields no results. A null feature would be one where the pipeline has been executed, but the feature value for that entity is null e.g. event counts for an entity would be 0 if the said entity did not trigger any events within the time window.\r\n\r\nIt would be useful if Feast returned metadata on features that have not been ingested yet. This could take on the form of a boolean mask that is applied to the resultant dataframe.","author":{"url":"https://github.com/thisisandreeeee","@type":"Person","name":"thisisandreeeee"},"datePublished":"2019-10-29T07:57:47.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":9},"url":"https://github.com/278/feast/issues/278"}
