Subject clarification on Partitioning Guidelines and CPU cores
Date Wed, 10 Oct 2018 21:02:54 GMT
Hi all,

can someone clarify if this recommendation below - does it mean physical or
hyper-threaded CPU cores? quite a big difference...

Partitioning Guidelines (https://kudu.apache.org/docs/
- For large tables, such as fact tables, aim for as many tablets as you
have cores in the cluster.
- For small tables, such as dimension tables, aim for a large enough number
of tablets that each tablet is at least 1 GB in size.

In general, be mindful the number of tablets limits the parallelism of
reads, in the current implementation. Increasing the number of tablets
significantly beyond the number of cores is likely to have diminishing
