class MongoPaginateBySizePartitioner extends Logging with MongoPartitioner with MongoPaginationPartitioner

The pagination by size partitioner.

Paginates the collection into partitions based on their size. Uses the collStats command and the average document size to estimate the partition boundaries.

Configuration Properties

The prefix when using sparkConf is: spark.mongodb.input.partitionerOptions followed by the property name:

*Note:* This can be a expensive operation as it creates 1 cursor for every estimated partitionSizeMBs worth of documents. *Note:* Does not support views. Use MongoPaginateByCountPartitioner or create a custom partitioner.
