Getting the byte size of a map

[Benjamin Juhn <be...@gmail.com>]

Do I need to create a udf for this is or is there something out there?

Thanks,

Byte size as in the runtime memory size of the map object or its
serialized byte size? Cause the latter can get complex to compute with
different storages and different storage options, right?

Or if you meant a trivial thing such as Map.size(), then nvm.

you'd need to make a UDF afaik, though if you dig around there may be code
that already does this (I'd look at Tuple's implementation of getting its
own size and see if it has something that does it for maps)
