# Comparison across Various Configurations

## Cache OM with Store versus Store OM Configuration

In TIBCO BusinessEvents, you can choose the object management (OM) strategy that you want for your application persistence. The following table provides a feature comparison between two persistence strategies:

- Cache OM with store
- Store OM

Features | Cache OM with Store | Store OM
--- | --- | ---
Expiry | When TTL expires for a concept, it is evicted from the entity cache as well as the object table after a specified delay (if legacy entity lookup strategy is used) | Data is removed directly from the store after the TTL expires.
Query Support | Query execution applies at the cache level. | Query execution applies at the store level, so the feature is limited to what the end store supports.
Data Recovery | Data recovery is applicable to cache configuration only. | Data recovery is not applicable to store configuration.

## Clustered (with Cache and/or Store) versus Unclustered (with Store) Configuration

You can use the clustered (with cache and/or store) or the unclustered configuration with store. The difference between using these configurations is that the clustered configurations support the following features:

- Fault tolerance support
- Distributed locking

These features are not supported by the unclustered with store configuration.
