Spring is JDBC-generic so I think we're good there. Improving our docs on
this topic is being discussed in https://github.com/apache/metron/pull/646
so hopefully this will be clear once that's worked out.

Anything spring based is likely multi-db by definition as long as a we pick a
good friendly ORM (not hibernate because licensing problems with apache,
eclipselink?) But I suspect we should pick a good default and that that default
should be postgres.

I'd vote for a DB-based solution, but I'd argue that any solution shouldn't
be database specific (i.e. postgres), but JDBC-generic. People and
organizations have very strong views regarding databases and I'd prefer to
side-step those holy wars by being agnostic.

Spring supports a variety of databases including Postgres. I have no
problem with using Postgres instead of MySQL.

Agreed on Postgres. It's a lot easier to work with license-wise in apache
projects, and has a lot of the capability we need here, especially if we can
find a sensible ORM. Anyone got any thoughts on what would work there?

Hi Ryan,
Zookeeper has a default (and seldom changed) max znode size of 1MB, but it is
“designed to store data on the order of kilobytes in size.”[1] And it’s not
really intended for frequently-changing data, which is okay here. But I just

Matt,
Thank you for the suggestions. I forgot to include Zookeeper. Are there
any tradeoffs we should be aware of if we decide to use Zookeeper? Are
there guidelines for how much data can be stored in Zookeeper?

There’s a couple other places you could put config info (but maybe not saved

- Zookeeper
- metron-alerts-ui/config.xml or config.json file
