* Compression heuristic.
*
- * For now is's a naive and optimistic 'return true', we'll extend the logic to
- * quickly (compared to direct compression) detect data characteristics
- * (compressible/incompressible) to avoid wasting CPU time on incompressible
- * data.
- *
* The following types of analysis can be performed:
* - detect mostly zero data
* - detect data with low "byte set" size (text, etc)
