        Config to enable/disable using mapper to do the below which are currently done in VPJ driver
        1. validate schema,
        2. collect the input data size
        3. build dictionary (if needed: refer VenicePushJob.shouldBuildZstdCompressionDictionary(com.linkedin.venice.hadoop.PushJobSetting, boolean))

        This new mapper was added because the sample collection for Zstd dictionary is currently in-memory and to help play around with the sample size and also to support future enhancements if needed.

        Currently, the plan is to only have it available for MapReduce compute engine and remove it eventually as we remove the MapReduce-related codes.

      • REWIND_TIME_IN_SECONDS_OVERRIDE

        public static final java.lang.String REWIND_TIME_IN_SECONDS_OVERRIDE
        Optional. If we want to use a different rewind time from the default store-level rewind time config for Kafka Input re-push, the following property needs to specified explicitly. This property comes to play when the default rewind time configured in store-level is too short or too long. 1. If the default rewind time config is too short (for example 0 or several mins), it could cause data gap with re-push since the push job itself could take several hours, and we would like to make sure the re-pushed version will contain the same dataset as the source version. 2. If the default rewind time config is too long (such as 28 days), it will be a big waste to rewind so much time since the time gap between the source version and the re-push version should be comparable to the re-push time if the whole ingestion pipeline is not lagging. There are some challenges to automatically detect the right rewind time for re-push because of the following reasons: 1. For Venice Aggregate use case, some colo could be lagging behind other prod colos, so if the re-push source is from a fast colo, too short rewind time could cause a data gap in the slower colos. Ideally, it is good to use the slowest colo as the re-push source. 2. For Venice non-Aggregate use case, the ingestion pipeline will include the following several phases: 2.1 Customer's Kafka aggregation and mirroring pipeline to replicate the same data to all prod colos. 2.2 Venice Ingestion pipeline to consume the local real-time topic. We have visibility to 2.2, but not 2.1, so we may need to work with customer to understand how 2.1 can be measured or use a long enough rewind time to mitigate all the potential issues. Make this property available in generic since it should be useful for ETL+VPJ use case as well.

      • REWIND_EPOCH_TIME_IN_SECONDS_OVERRIDE

        public static final java.lang.String REWIND_EPOCH_TIME_IN_SECONDS_OVERRIDE
        A time stamp specified to rewind to before replaying data. This config is ignored if rewind.time.in.seconds.override is provided. This config at time of push will be leveraged to fill in the rewind.time.in.seconds.override by taking System.currentTime - rewind.epoch.time.in.seconds.override and storing the result in rewind.time.in.seconds.override. With this in mind, a push policy of REWIND_FROM_SOP should be used in order to get a behavior that makes sense to a user. A timestamp that is in the future is not valid and will result in an exception.
