  - setOffload
```
public MapStoreConfig setOffload(boolean offload)
```
    Default value is true.
    MapStore interaction can be slow compared to in-memory processing of data, to make partition threads available during MapStore interaction for other cluster operations, MapStore/MapLoader implementations are offloaded from partition threads to a different thread pool by default.
    If you set this property to false, MapStore interaction will be done on partition threads. This may introduce latency for other operations which don't require MapStore interaction.
    
    Parameters:
    
    offload - set true to enable offloading, otherwise set false
    
    Since:
    
    5.2
