# Manage Data Volume

> Keep costs predictable and queries fast by filtering telemetry, configuring sampling, and right-sizing your Refinery cluster for your data volume.

Managing your data volume will help you keep costs predictable and manageable, and keep Honeycomb's queries speedy.
Use our recommended techniques and tooling to reduce the size of your data, optimize your storage capacity, and improve your performance and scalability.
