Hi, In newts data model, the samples would be sorted by collect time and then the metric name, so when we request a graph, all samples of the requested time range of the requested resource id would be loaded from Cassandra at once and then only the requested datasources would be filtered as final results in java. I am aware of the idea behind this policy : most of the time, graphs contain multiple data sources of a specific resourceId so they all would be fetched in a single access to Cassandra (to be fast). Now My problem is with jmx service that uses a hard coded interfaceSnmp as resource type, i have a jmx service with 2 thousands data sources in it so retrieving a graph for datasources of this resourceId took more than 20 seconds while other graphs would be loaded in less than 200ms.
