Hi, is connecting to multiple clusters using the same java FDB instance possible e.g. using createCluster(java.lang.String clusterFilePath) to create 2 separate cluster instances? Thanks

Yes, you can connect to multiple clusters in the same instance using multiple calls to [createCluster](https://apple.github.io/foundationdb/javadoc/com/apple/foundationdb/FDB.html#createCluster-java.lang.String-) (or the more typically used [FDB.open](https://apple.github.io/foundationdb/javadoc/com/apple/foundationdb/FDB.html#open-java.lang.String-) method).

If the clusters are running at multiple incompatible versions, you would need to use the [multi-version client](https://apple.github.io/foundationdb/api-general.html?#multi-version-client) to be able to connect to them.

The [createCluster](https://apple.github.io/foundationdb/javadoc/com/apple/foundationdb/FDB.html#createCluster-java.lang.String-) method is deprecated.

`createCluster()` was deprecated in favor of the `FDB.open()` function, which is still available and can be used in a similar way for this purpose.
