########## File path: site/docs/latest/cookbooks/compaction.md ########## @@ -0,0 +1,113 @@ +--- +title: Topic compaction cookbook +tags: [admin, clients, compaction] +--- + +Pulsar's [topic compaction](../../getting-started/ConceptsAndArchitecture#compaction) feature enables you to create **compacted** topics in which older, "obscured" entries are pruned from the topic, allowing for faster reads through the topic's history (which messages are deemed obscured/outdated/irrelevant will depend on your use case). + Review comment: A simple motivating usecase would be helpful here. The one I'm going to use for an upcoming is a stock ticker. Some users will want to see just the latest value for each stock, while some want to see the whole history of how the prices changed over time. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
