31.10. Limitations when Executing Stored Scripts

Java Streams throw an error when used with clusters in DIST mode

It is not possible to use scripts that create a Stream in JavaScript when the cluster is in DIST mode. Any attempts to execute these scripts will result in a NotSerializableException, as the lambdas fail when attempting to be serialized. To workaround this issue it is recommended to manually iterate over data using an Iterator, or to execute lambdas after the data has been transferred from the script to the originator node.

There are no issues using streams in clusters with other modes.
