Rollup aggregation limitations

edit

This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.

For version 8.5 and above we recommend downsampling over rollups as a way to reduce your storage costs for time series data.

There are some limitations to how fields can be rolled up / aggregated. This page highlights the major limitations so that you are aware of them.

Limited aggregation components

The Rollup functionality allows fields to be grouped with the following aggregations:

  • Date Histogram aggregation
  • Histogram aggregation
  • Terms aggregation

And the following metrics are allowed to be specified for numeric fields:

  • Min aggregation
  • Max aggregation
  • Sum aggregation
  • Average aggregation
  • Value Count aggregation
