+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.

+
+## Total memory
+
+The *total memory* in Flink consists of JVM heap, [managed memory](#managed-memory) and [network buffers](#network-buffers).
+[Managed memory](#managed-memory) can be either part of JVM heap or direct off-heap memory.
