ExternalAppendOnlyMap

class ExternalAppendOnlyMap[K, V, C] extends Iterable[(K, C)] with Serializable with Logging with Spillable[SizeTracker]

:: DeveloperApi :: An append-only map that spills sorted content to disk when there is insufficient space for it to grow.

This map takes two passes over the data:

(1) Values are merged into combiners, which are sorted and spilled to disk as necessary (2) Combiners are read from disk and merged together

The setting of the spill threshold faces the following trade-off: If the spill threshold is too high, the in-memory map may occupy more memory than is available, resulting in OOM. However, if the spill threshold is too low, we spill frequently and incur unnecessary disk writes. This may lead to a performance regression compared to the normal case of using the non-spilling AppendOnlyMap.

Two parameters control the memory threshold:

spark.shuffle.memoryFraction specifies the collective amount of memory used for storing these maps as a fraction of the executor's total memory. Since each concurrently running task maintains one map, the actual threshold for each map is this quantity divided by the number of running tasks.

spark.shuffle.safetyFraction specifies an additional margin of safety as a fraction of this threshold, in case map size estimation is not sufficiently accurate.
