Change Logs

This is part of a larger feature support where we are adding streaming write support to metadata table. We are going to raise lot of smaller patches as part of https://issues.apache.org/jira/browse/HUDI-9281. Goal is to keep producing small patches that can land in isolation w/o being blocked on very large patch. for overall design, feel free to check out https://github.com/apache/hudi/pull/13236

We are adding a new abstraction named HoodieMetadataWriterWrapper which is the interface for SparkRDDwriteClient and SparkRDDTableServiceClient. Irrespective of whether streaming writes are enabled or not, we keep all intricacies within the HoodieMetadataWriterWrapper(like the life cycle management of diff metadata writers corresponding to each action in data table in case of streaming writes). We just don't wanna pollute the core RDDwriteClient or the the TableServiceClient w/ the streaming writer state management and interactions.

Impact

Able to do streaming writes to metadata table directly w/ rdd based off of data table writes.

Risk level (write none, low medium or high below)

high
