+Apache Flink provides efficient workloads on top of the JVM by tightly controlling the memory usage of its various components.
+While the community strives to offer sensible defaults to all configurations, the full breadth of applications
+that users deploy on Flink means this isn't always possible. To provide the most production value to our users,
+Flink allows both high level and fine-grained tuning of memory allocation within clusters.
+

+
+The further described memory configuration is applicable starting with the release version *1.10*. If you upgrade Flink
+from earlier versions, check the [migration guide](mem_migration.html) because many changes were introduced with the 1.10 release.
+
+<strong>Note:</strong> This memory setup guide is relevant <strong>only for task executors</strong>!
+Check [job manager related configuration options](../config.html#jobmanager) for the memory setup of job manager.
+
+## Configure Total Memory
+
+The *total process memory* of Flink JVM processes consists of memory consumed by Flink application (*total Flink memory*)
+and by the JVM to run the process. The *total Flink memory* consumption includes usage of JVM heap,
+*managed memory* (managed by Flink) and other direct (or native) memory.

+
+If you run FIink locally (e.g. from your IDE) without creating a cluster, then only a subset of the memory configuration
+options are relevant, see also [local execution](#local-execution) for more details.
+
+Otherwise, the simplest way to setup memory in Flink is to configure either of the two following options:
+* Total Flink memory ([taskmanager.memory.flink.size](../config.html#taskmanager-memory-flink-size-1))
+* Total process memory ([taskmanager.memory.process.size](../config.html#taskmanager-memory-process-size-1))
 
 Review comment:
   These two links do not work for me. Why do we have `-1` in the urls?
   Is it a mistake or something wrong with my building?
