@jhamman yes, I think it's alright to close. The issue seems to arise from the use of .tolist(), having to convert every value to a python float so that it may be retuned in a dictionary as is acceptable for JSON, causing the memory spike.

will try @Illviljan suggestion (thanks!) , to_json calls .compute but not sure if it calls .tolist(), in case it avoids it, that should result in greater memory efficiency.
