> Amazon S3 among other cloud object stores, throttle requests based on object prefix => [https://aws.amazon.com/premiumsupport/knowledge-center/s3-request-limit-avoid-throttling/]. Hudi follows the traditional Hive storage layout, with files being stored under separate partition paths under a common table path/prefix. This introduces the potential for throttling because of request limits being reached for the common table path/prefix, when writing significant number of files concurrently.
> We propose implementing an alternate storage layout, that would be more suitable for cloud object stores like S3 to avoid running into throttling issues as the data scales. At a high level, we need to be able to distribute data files evenly across randomly generated prefixes, so that request limits get distributed across those prefixes, instead of a single table prefix.
