Each request to the GetMetricData API can include 100 queries. This means that each panel in Grafana will only issue one GetMetricData request, regardless of the number of query rows that are present in the panel. Consequently as it is no longer possible to set `HighRes` on a per query level anymore, this switch is now removed from the query editor. High resolution can still be achieved by choosing a smaller minimum period in the query editor.
The handling of multi template variables in dimension values has been changed in Grafana 6.5. When a multi template variable is being used, Grafana will generate a search expression. In the GetMetricData API, expressions are limited to 1024 characters, so it might be the case that this limit is reached when a multi template variable that has a lot of values is being used. If this is the case, we suggest you start using `*` wildcard as dimension value instead of a multi template variable.
