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)
