Hi
I have data frames created every 5 minutes. I use a dict to keep the recent
1 hour data frames. So only 12 data frame can be kept in the dict. New data
frame come in, old data frame pop out.
My question is when I pop out the old data frame, do I have to call
dataframe.unpersist to release the memory?
For example
If currentTime == fiveMinutes:
myDict[currentTime] = dataframe
oldestDataFrame = myDict.pop(oldest)
Now do I have to call oldestDataFrame.unpresist? Because I think python
will automatically release unused variable
