Hong Liang Teoh updated FLINK-32488:
------------------------------------
Description:
*What*
Currently, REST handlers that inherit from AbstractExecutionGraphHandler serve
information derived from a cached ExecutionGraph.
This ExecutionGraph cache currently derives it's timeout from
{*}web.refresh-interval{*}. The *web.refresh-interval* controls both the
refresh rate of the Flink dashboard and the ExecutionGraph cache timeout.
We should introduce a new configuration to control the ExecutionGraph cache,
namely {*}rest.cache.execution-graph.expiry{*}.
*Why*
Sharing configuration between REST handler and Flink dashboard is a sign that
we are coupling the two.
Ideally, we want our REST API behaviour to independent of the Flink dashboard
(e.g. supports programmatic access).
