Change Logs
First steps towards integrating of Spark Datasource V2 were taken in RFC-38, which is now marked as completed. However, there are multiple issues with advertising Hudi table as V2 without actual implementing certain API, and with using custom relation rule to fall back to V1 API. As a result, the current implementation of
HoodieCatalogandSpark3DefaultSourcereturns aV1Tableinstead ofHoodieInternalV2Table, in order to address performance regression.There was an attempt to implement Spark Datasource V2 read functionality as a regular task, but it failed due to the scope of work required. Therefore, this RFC proposes to discuss design of Spark Datasource V2 integration in advance and to continue working on it accordingly.
