Key | Default | Type | Description
--- | --- | --- | ---
##### rest.async.store-duration | 5 min | Duration | Maximum duration that the result of an async operation is stored. Once elapsed the result of the operation can no longer be retrieved.
##### rest.await-leader-timeout | 30 s | Duration | The time that the client waits for the leader address, e.g., Dispatcher or WebMonitorEndpoint
##### rest.cache.checkpoint-statistics.size | 1000 | Integer | Maximum number of entries in the checkpoint statistics cache.
##### rest.cache.checkpoint-statistics.timeout | 3 s | Duration | Duration from write after which cached checkpoints statistics are cleaned up. For backwards compatibility, if no value is configured, `web.refresh-interval` will be used instead.
##### rest.client.max-content-length | 104857600 | Integer | The maximum content length in bytes that the client will handle.
##### rest.connection-timeout | 15 s | Duration | The maximum time for the client to establish a TCP connection.
##### rest.flamegraph.cleanup-interval | 10 min | Duration | Time after which cached stats are cleaned up if not accessed. It can be specified using notation: "100 s", "10 m".
##### rest.flamegraph.delay-between-samples | 50 ms | Duration | Delay between individual stack trace samples taken for building a FlameGraph. It can be specified using notation: "100 ms", "1 s".
##### rest.flamegraph.enabled | false | Boolean | Enables the experimental flame graph feature.
##### rest.flamegraph.num-samples | 100 | Integer | Number of samples to take to build a FlameGraph.
##### rest.flamegraph.refresh-interval | 1 min | Duration | Time after which available stats are deprecated and need to be refreshed (by resampling). It can be specified using notation: "30 s", "1 m".
##### rest.flamegraph.stack-depth | 100 | Integer | Maximum depth of stack traces used to create FlameGraphs.
##### rest.idleness-timeout | 5 min | Duration | The maximum time for a connection to stay idle before failing.
##### rest.profiling.dir | System.getProperty("java.io.tmpdir") | String | Profiling result storing directory.
##### rest.profiling.duration-max | 5 min | Duration | Maximum profiling duration for each profiling request. Any profiling request's duration exceeding this value will not be accepted.
##### rest.profiling.enabled | false | Boolean | Enables the experimental profiler feature.
##### rest.profiling.history-size | 10 | Integer | Maximum profiling history instance to be maintained for JobManager or each TaskManager. The oldest instance will be removed on a rolling basis when the history size exceeds this value.
##### rest.retry.delay | 3 s | Duration | The time that the client waits between retries (See also `rest.retry.max-attempts`).
##### rest.retry.max-attempts | 20 | Integer | The number of retries the client will attempt if a retryable operations fails.
##### rest.server.max-content-length | 104857600 | Integer | The maximum content length in bytes that the server will handle.
##### rest.server.numThreads | 4 | Integer | The number of threads for the asynchronous processing of requests.
##### rest.server.thread-priority | 5 | Integer | Thread priority of the REST server's executor for processing asynchronous requests. Lowering the thread priority will give Flink's main components more CPU time whereas increasing will allocate more time for the REST server's processing.
