Abstract: Embodiments of the present invention relate to a method, system, and computer program product for compacting data in a distributed storage system. In some embodiments, a method is disclosed. According to the method, first information about historical resource usage of a data node and second information about a historical data compaction performed at the data node are obtained. The historical data compaction compacted data files associated with a first database table into one data file. A configuration for a data compaction to be performed on a plurality of data files associated with a second database table is generated based on the first and second information. The data compaction is performed during a future time period. In other embodiments, a system and a computer program product are disclosed.

Abstract: A method for enabling applications to compress and un-compress selected objects based on defined rules is provided. The method may include generating un-compressed objects and proxy objects, and storing the generated un-compressed objects on an un-compressed objects storage. The method may include receiving defined rules. The method may include compressing the stored un-compressed objects based on the defined rules, and storing the generated compressed objects on a compressed objects storage. The method may include receiving requests to invoke methods. The method may include in response to a determination that the received requests are to invoke methods associated with the un-compressed objects, retrieving the stored un-compressed objects. The method may include in response to a determination that the received requests are to invoke methods associated with the stored compressed objects, retrieving the compressed objects. The method may include restoring the retrieved compressed objects.
