Subject Re: Blog post on Cassandra's inner workings and performance - feedback welcome
Date Sat, 09 Jul 2016 16:58:51 GMT
I saw this really useful post a few days ago. I found the organization and
presentation quite clear and helpful (I often struggle trying to do high
level comparisons of Hadoop and Cass). Thank you!

If there was sections I would like to see your clear thoughts appear
within, it would be around:

   - (1) why networks need to be clean (the impact of "dirty"/erratic
   networks);
   - (2) the impact of java (off heap, stop the world garbage collection,
   why more memory makes things worse;
   - (3) table design decisions (read mostly, write mostly, mixed
   read/write, etc.)

A really great writeup, thank you!
