> This would be inconsistent with the expectation of the storage level set on the RDD/DF. > Instead, what we can do is prefer disk in case it is available as an option (if `storageLevel.useDisk == true`) @mridulm That's correct. In the current flow of decommissioning,the blocks being offloaded can replace existing cached blocks on peer block manager if enough memory is not available. This way we are saving one cached block by loosing another. If this change is in, we can avoid loosing cached blocks to place offloading cached blocks.
