Right, here we could use the level if specified. I expect most topics to use `compression.type=producer` but in case a specific compression type and level is set, that would make sense to use them. 2. It's not something I thought about before. Do you think there are scenarios where the gains of picking a different level for older data would be significant enough to motivate such a feature? -- This is an automated message from the Apache Git Service.
