Subject Re: Cassandra users survey

Thanks for all the responses!

The results (minus suggestions and emails) are available here:

I've included charts on separate sheets for each question, but
unfortunately I couldn't figure out how to help Google make sense of any of
the data where the form allowed multiple or free-form responses.

Some things that jump out at me:

- 3/4 of responses use only CQL.
- 3% have more than 1000 tables in the schema. On an absolute scale this is
low but still more than I expected.
- 60% are deployed across more than one datacenter
- I should have broken down the node count responses into more detail;
roughly 50% each in 1-10 and 10-100.  I should also include an "are you in
production?" question next time.
- More responses of both "less than 32 GB ram/node" and "128 GB or more"
than I expected.
- Including the "both" responses, a majority of users are deploying SSD now.
