Broadcast variables need to fit entirely in memory - so that's a
pretty good litmus test for whether or not to broadcast a smaller
dataset or turn it into an RDD.

Anyone have any guidance on using a broadcast variable to ship data to
workers vs. an RDD?
Like, say I'm joining web logs in an RDD with user account data. I could
keep the account data in an RDD or if it's small, a broadcast variable
instead. How small is small? Small enough that I know it
I had like to be corrected on this but I am just trying to say small enough
of the order of few 100 MBs. Imagine the size gets shipped to all nodes, it
can be a GB but not GBs and then depends on the network too.
