Rollups in Open Distro

Given that Open Distro does not support Elasticsearch’s Rollup API, does anyone have a workaround for rolling up data? We have the requirement for long term retention of a few fields from indices that have short-term retention.

I’ve read Rollup Support in Open Distro which indicates that the rollup feature is not part of opendistro at this point. I have thumb’ed up the feature request: https://github.com/opendistro-for-elasticsearch/community/issues/88.

Would love to hear how others are doing this. Thanks!
