# Design for Data Locality

Learn to keep related data on the same node, verify that it stays there, run compute next to the data, and decide when to break colocation on purpose.

Learn to keep related data on the same node, verify that it stays there, run compute next to the data, and decide when to break colocation on purpose. Two how-to guides complete the path: [Choose a Partition Count for Your Workload](/docs/gridgain/gridgain-8/gridgain8-get-started/how-to-guides/choose-partition-count.md) and [Debug a Hot Partition](/docs/gridgain/gridgain-8/gridgain8-get-started/how-to-guides/debug-hot-partition.md).

Complete [Cache-Centric Foundations](/docs/gridgain/gridgain-8/gridgain8-get-started/learning-paths/cache-centric-foundations.md) first.
