Subject Hints about encoding and compression
Date Mon, 05 Dec 2016 13:21:21 GMT
Hi,


I'm evaluating Kudu and I'd need some hints about column encoding and compression.


A- Does it make sense adding LZ4 compression to a field with Dictionary Encoding ?
B- Does it make sense adding LZ4 compression to a field with Run-Length Encoding ?

C- I have a non-key column with randomly distributed INT32 numbers, I guess I won't add an
encoding. But what about compression ? Would LZ4 make sense ? Would it slow down aggregations
(`SUM`) ?




Thank.
Nicolas
