# Compaction Strategies

This simulation shows the ScyllaDB write path: **write → commitlog → memtable →
flush → compaction**.

* Select a compaction strategy: Incremental (ICS), Leveled (LCS), or
  Time-Window (TWCS).
* Select a workload, and see SSTables accumulate and merge.
* The simulation measures space, write, and read amplification from the
  simulated data.
* The sub-properties have the same names as the
  [CQL compaction options](https://docs.scylladb.com/manual/stable/cql/compaction.html).

#### NOTE
This is an educational simulation. It is simplified, and it does not show
all of the ScyllaDB internals exactly.
