cluster.evenly-spread-out-slots |
false |
Boolean |
Enable the slot spread out allocation strategy. This strategy tries to spread out the slots evenly across all available `TaskExecutors`. |
cluster.io-pool.size |
(none) |
Integer |
The size of the IO executor pool used by the cluster to execute blocking IO operations (Master as well as TaskManager processes). By default it will use 4 * the number of CPU cores (hardware contexts) that the cluster process has access to. Increasing the pool size allows to run more IO operations concurrently. |
cluster.processes.halt-on-fatal-error |
false |
Boolean |
Whether processes should halt on fatal errors instead of performing a graceful shutdown. In some environments (e.g. Java 8 with the G1 garbage collector), a regular graceful shutdown can lead to a JVM deadlock. See FLINK-16510 for details. |
cluster.registration.error-delay |
10000 |
Long |
The pause made after an registration attempt caused an exception (other than timeout) in milliseconds. |
cluster.registration.initial-timeout |
100 |
Long |
Initial registration timeout between cluster components in milliseconds. |
cluster.registration.max-timeout |
30000 |
Long |
Maximum registration timeout between cluster components in milliseconds. |
cluster.registration.refused-registration-delay |
30000 |
Long |
The pause made after the registration attempt was refused in milliseconds. |
cluster.services.shutdown-timeout |
30000 |
Long |
The shutdown timeout for cluster services like executors in milliseconds. |
