It would only trigger compaction if sst tables have overlapping keys. And if you only write new items, goleveldb implementation would just create 3.7Mb sst tables by default without trying to merge them into bigger chunks (what's the point? they are all sorted and non-overlapping). When you have queue consumption workload it would start merging tombstones with sst tables and since tombstones are also in sorted order it would not pick up multiple sst tables at a time, and just either completely or partially remove stale sst files. I added some more benchmarks including queue packing with 200M messages of 64 byte size, and benchmarks of consumption of 200M messages. The speed is sustainable. https://github.com/bogdanovich/siberite/blob/master/docs/ben...
