# AMutableStoreConfig

**Javadoc**: [AMutableStoreConfig](https://artifacts.activeviam.com/documentation/accelerators/tools/dash/2.0.0-AP5.9/javadoc/com/activeviam/tools/datastore/impl/AMutableStoreConfig.html)

Abstract class defining the logic for the configuration-related methods in the core Atoti Server API (such as partitioning, NUMA node selection, and duplicate key behaviour). Stores all configuration calls to be forwarded to the core APIs and provides merging logic for multiple sets of configuration.

This object partially implements the `IMutableStore` interface, but does not implement any core Atoti Server APIs.
