- This change breaks `hudi-client` into `hudi-client-common` and `hudi-spark-client` modules - Simple usages of Spark using jsc.parallelize() has been redone using EngineContext#map, EngineContext#flatMap etc - Code changes in the PR, break classes into `BaseXYZ` parent classes with no spark dependencies living in `hudi-client-common` - Classes on `hudi-spark-client` are named `SparkXYZ` extending the parent classes with all the Spark dependencies - To simplify/cleanup, HoodieIndex#fetchRecordLocation has been removed and its usages in tests replaced with alternatives Co-authored-by: Vinoth Chandar <vinoth@apache.org>

bin/custom-delta-streamer-example.sh -
For hudi delta streamer demo of dfs source:
4.1 Prepare dfs data, we have provided
src/main/resources/delta-streamer-config/dfs/source-file.jsonfor test4.2 Run
bin/dfs-delta-streamer-example.sh -
For hudi delta streamer demo of dfs source:
5.1 Start Kafka server
5.2 Configure your Kafka properties, we have provided
src/main/resources/delta-streamer-config/kafka/kafka-source.propertiesfor test5.3 Run
bin/kafka-delta-streamer-example.sh5.4 continuously write source data to the Kafka topic your configured with
hoodie.deltastreamer.source.kafka.topicinkafka-source.properties -
Some notes delta streamer demo:
6.1 The configuration files we provided is just the simplest demo, you can change it according to your specific needs.
