      Left side is MongoDB option name; -> right side is equivalent WiredTiger configuration option.

      Options for --wiredTigerEngineConfig

      cacheSizeMB: number -> cache_size=number MB
      checkpointPeriodSecs: number -> checkpoint=(wait=number)
      checkpointSizeBytes: number -> checkpoint=(log_size=number)
      statisticsLogPeriodSecs: number -> statistics_log=(wait=number)
      

      Options for --wiredTigerCollectionConfig, --wiredTigerIndexConfig

      compression: compressor -> block_compressor=compressor, compressor=\{snappy, zlib, none\}
      maxLeafPageSizeKB: number -> leaf_page_max=number KB
      overflowSizeBytes: number -> leaf_item_max=number
      maxPageMemorySizeKB: number -> memory_page_max=number
      prefixCompression: boolean -> prefix_compression=boolean   (default on for indexes)
      

      These options will be validated regardless of the current storage engine; this is to make mixed storage-engine replica sets work.
