Dhruba Borthakur 5273c81483 Ability to invoke application hook for every key during compaction. ... Summary: There are certain use-cases where the application intends to delete older keys aftre they have expired a certian time period. One option for those applications is to periodically scan the entire database and delete appropriate keys. A better way is to allow the application to hook into the compaction process. This patch allows the application to set a method callback for every key that is being compacted. If this method returns true, then the key is not preserved in the output of the compaction. Test Plan: This is mostly to preview the proposed new public api. Since it is a public api, please do due diligence on reviewing it. I will be writing test cases for this api in mynext version of this patch.
