Subject Composite primary key
Date Sat, 26 Aug 2017 06:10:50 GMT

We're inserting messages from kafka into kudu tables and some messages
don't have a natural primary key, hence we decided to use kafka
topic/partition/offset -combination as the key. Is it better to concatenate
the fields into one kudu column or create a separate column for each? Do we
get better compression if using individual columns? And is the PK index
structure maintained outside of the actual table data?
