             Summary: JDBC: support FQDN to multiple IPs during connection establishment
                 Key: IGNITE-7192
                 URL: https://issues.apache.org/jira/browse/IGNITE-7192
             Project: Ignite
          Issue Type: Improvement
          Components: jdbc
    Affects Versions: 2.1
            Reporter: Alexey Popov


Thin JDBC driver may have FQDN (host name) at a connection string.
Currently, it resolves this FQDN to one IP and tries to connect to this IP only.
It is better to try to connect to multiple IPs one-by-one if DNS returns multiple A-records
(FQDN can be resolved to several IPs) until successful connection. It could give a simple
fallback option for the JDBC thin driver users.

A similar functionality is already implemented in ODBC driver.
