pedro93 opened a new issue #6912: URL: https://github.com/apache/incubator-pinot/issues/6912
Hello, This issue serves to request support for segment compaction on real-time upsert-enabled tables which currently does not exist as mentioned in a [slack thread](https://apache-pinot.slack.com/archives/CDRCA57FC/p1620826182368300). This means that segments with old & stale entries are keep in disk and only deleted when the retention policy for segments is activated. Giving a concrete example why this is useful: - Suppose you have have a stream of events related to user activity (updated profile, saw an article, updated preferences, etc...) - Defined a real-time table in pinot where the primary key is the userId. Segment size is 500k and the stream is partitioned. - The set of users is roughly fixed (~50M). - You want to keep segments for a largeish time period (> 2 years). - Each day ~20% (10M) of the users generate some event which is consumed by Pinot. This will generate ~20 segments per day, over the course of 2 years we will have 14600 segments when in reality we need only 100 segments (the most up-to-date information for each user). If the example or issue is not clear feel free to reach out. Thank you. -- This is an automated message from the Apache Git Service.
