> Issue Type: New Feature
> Components: atlas-intg, atlas-webui
> Affects Versions: 2.1.0
> Reporter: JP
> Assignee: Disha Talreja
> Priority: Major
>
> # Create new typeDef of MetricsStat to persist Metrics entity.
> # Create MetricsStat class to keep Metrics' info about collectionTime,
> metricsId and ttl; create MetricsStatsDTO class to transfer states between
> MetricsStat and AtlasEntity when it is saved or retrieved from JanusGraph.
> # Create MetricsStatMin to represent the minimal information about persisted
> MetricsStat.
> # Create job scheduler with configurable metrics.persist.schedule (default
> as 7 days) & metrics.ttl.hours (default as 1 hr interval) to save a metrics
> entity to db and to sweep through all metrics entities and clear the ones
> whose time-to-live (ttl) has past.
> # Update MetricsService to implement REST APIs in AdminResource to realize
> api calls of:
> ** Get all persisted metricsStats, with boolean variable to choose its
> return type as a list of metricsStats with specific details, or with minimal
> information;
> ** Get a specific metricsStat by collectionTime
> # Update MetricsService to include helper methods of:
> ** Save a metricsStat to db
> ** Get or delete a persisted metricsStat by collectionTime
> ** Purge metricsStats whose ttl has past
