`real-time` `ingestion` `feature` Part 2 of https://github.com/apache/pinot/pull/15782 Issue https://github.com/apache/pinot/issues/14815 Design doc https://docs.google.com/document/d/1NKPeNh6V2ctaQ4T_X3OKJ6Gcy5TRanLiU1uIDT8_9UA/edit?usp=sharing Introduce the new ephemeral type of topic in multi-topic ingestion. The main difference would be the segment name. **For such type of topic, the segment name would be `tableName__topicName__partitionGroupId__sequenceNumber__creationTime` instead of `tableName__partitionGroupId__sequenceNumber__creationTime`.** This change is supposed to be no-op at the moment because such naming would not be applied to any ingestions. Afterwards, this would be used to: - [Short-term]Support skip interval backfill for offset auto reset during real-time ingestion lag (configurable). - [Mid/Long-term]Replace the existing multi-topic ingestion naming format. So that it would be easy to remove topics from multi-topic table. Other changes: - Ensure each stream could use their own streamConfig instead of sharing the configs from the first streamConfig. Removing the streamConfigs.get(0) usage. - Does not allow duplicate stream (same stream type with same topic name) - [Tentative] Does not allow deleting topics. Deleting topics is not banned currently, but it is not a safe operation as segment metadata mapping would be messed. -- This is an automated message from the Apache Git Service.
