   I'll take a look. Might be system cache behavior. It might prefetch part of the data volume into memory. BTW, what query are you using in Grafana?

   Well, it's the same query (or set of queries) every time and the system eventually runs out of memory when I do this, so no, this is memory directly allocated by akumulid.

   My graph targets are simple and mostly look like this:

         "targets": [
           {
             "aggregator": "sum",
             "alias": "",
             "currentTagKey": "pos",
             "currentTagValue": "bell",
             "downsampleAggregator": "mean",
             "downsampleFillPolicy": "none",
             "metric": "temp",
             "refId": "A",
             "tags": {
               "set": "outdoor"
             }
           },
           {
             "aggregator": "sum",
             "alias": "Gartenwasser",
             "currentTagKey": "",
             "currentTagValue": "",
             "downsampleAggregator": "mean",
             "downsampleFillPolicy": "none",
             "metric": "flow",
             "refId": "B",
             "tags": {
               "loc": "ug",
               "pos": "garden",
               "type": "sensor"
             }
           }
         ],
