Write performance vs RocksDB

[vorcigernix]

I picked RocksDB for my side project for following reasons:

Write Performance:
LSM tree structure optimized for write-heavy workloads
Write amplification is minimized compared to B-tree databases
Efficient compaction strategies

Merging performance:
Good for "tree merging" scenarios where identities/records form tree-like structures

Is Limbo something I should put on my radar? My current code is capable of merging ~5k records per second (very simple event-like structures) on my M3 Air, 16GB memory. Thing is that horizontal scaling is kinda problematic with Rocks and while this is clearly a premature optimization to do, I am also continually discovering the options for the day I come to this bridge.
