Thread: Is Drools Ready For Production?

  1. #1

    Default Is Drools Ready For Production?

    I've been looking into using Drools to implement some business logic in kettle. But I notice that the drools integration is listed under experimental.

    Is this ready for production or not?

    Unfortunately it is not.

    For a few reasons

    - there is a bug with processing the rows. It has been fixed but I'm not sure that the fix has made to a CE release yet.
    - the version is pretty old with some quirks that have been ironed out in later releases
    - the usage is cumbersome

    However, I have submitted a patch to upgrade to version 5.5 (with an outlook to upgrade to v 6 ASAP). Unfortunately it has not been taken in as yet.

    Please vote here - http://jira.pentaho.com/browse/PDI-10657

    Hope that helps.

    It helps but unfortunately doesn't give me a rules engine to use with kettle. Is there any alternatives?

    I was not able to come up with any other alternative.
    With the 5.0.1 embedded into the kettle engine directly any other version will be conflicting with it.

    So for my needs - there is no other way unfortunately.

    Would be really interested to know if you come up with a solution.

    Hmm... how much effort do you think is involved in getting the drools step production ready? We might be interested in helping out.

    Cheers
