Currently, we will retrieve all the contents of the field if that field is specified in the query API. In case of configs and metrics, this can become a lot of data even though the user doesn't need it. So we need to provide a way to query only a set of configs or metrics. As a comma spearated list of configs/metrics to be returned will be quite cumbersome to specify, we have to support either of the following options : # Prefix match # Regex # Group the configs/metrics and query that group. We also need a facility to specify a metric time window to return metrics in a that window. This may be useful in plotting graphs -- This message was sent by Atlassian JIRA (v6.3.4#6332)
