I have read through the Cloudera documentation relating to query plans and profiles and it is pretty good.
But I do not see a comprehensive glossary of terms used. Is any other source of information available?
For example I have this operation in my plan:
08:SCAN HDFS […, RANDOM]
partitions=1/1 files=1 size=286.16KB
runtime filters: RF000 -> inihpi.state, RF001 -> inihpi.yyyyqq
Is there a place where it is defined what RANDOM means in this context?
That is just an example but I was curious if there is a glossary that gives a full listing of all terms used and their meanings.
