Subject Re: What is jdbc:ignite:cfg ??
Date Thu, 10 Dec 2015 19:29:36 GMT
Andrey,

I agree on both points. However, I still think that we should provide
sample step-by-step guide with a sample configuration. This configuration
should include a couple of data types, like Person and Organization, define
indexes for them, etc.

This guide should include:

1. Start Ignite Servers
2. Populate data - should have example with configuration.
3. Query data using JDBC driver - example code and, if needed,
configuration to support it.

Do you mind adding it?

D.
