Are INTEL cpu required ? If not INTEL can be removed ? (also running typo)

Wasn't stormdb bought by another company ? Is there an opensource
alternative ? Fix the "patche" typo ?

A way to make it simpler is by merging coordinator and datanode into 1 and
making it possible for a 'node' to not hold data (be a coordinator only),
like in elastic-search, but you probably already know that.

What exact things does the gtm-proxy do? For example, a single row insert
wouldn't need the gtm (coordinator just inserts it to the right
data-node)(asumming no sequences, since for that the gtm is needed)?

If multiple tables are sharded on the same key (example: user_id). Will all
the rows, from the same user in different tables be in the same data-node ?
