Description

This represents the point at which we should switch from a memory storage into a file storage.

Defaults is 100 Kb.

Obviously this parameter is important:

• Higher values will operate mostly in-memory thus will have low latencies but will trash the heap and might trigger a GC hell.
• Lower values will defensively operate on files. Higher latencies but predictable throughtput. Modern SSDs and FS cache should enable to keep up with high rates.

Optimally we should have some bench showing the impact of this parameter.
