Hi all As part of my MSc project, I've done a new compaction strategy for Cassandra, called Burst Hour Compaction Strategy. You can find the JIRA ticket here: https://issues.apache.org/jira/browse/CASSANDRA-12201
In a nutshell, the background compaction for this strategy is only triggered during a predefined interval, freeing the resources during other times of the day. It also tries to make keys unique across all the SSTables, when these keys that are present in more than a configurable number of tables. Please check the JIRA ticket for a full description. The code can be found here: https://github.com/sedulam/CASSANDRA-12201 Please let me know what you think, or improvements that can be done (some ideas are in the ticket description). Since I'm new to Cassandra, I imagine that a lot of assumptions might not be the best, e.g. 100MB for the maximum table size. I'm looking forward to working with this community! All the best Pedro Gordo
