If metrics that have the same timestamp and dimensions aren't grouped into the same document, ES will consider them to be a duplicate. This adds a hash of the metric names that will be mapped as a dimension in Elasticsearch. The tradeoff is that if the composition of the metrics grouping changes over time, a new time series will be created. That has an impact on the rate aggregation for counters.
