Analysing source code on JMeter, (http://svn.apache.org/viewvc/jmeter/trunk/src/protocol/jdbc/org/apache/jmeter/protocol/jdbc/AbstractJDBCTestElement.java?view=markup) , the timeout is always passed to the Driver.

As commented we should fill an issue in order to request that feature. I don't see we should not not have that kind of configuration; not setting and using defaults from drivers should be valid. In arguments for  timeout value should be >= 0; the 0 means there is no limit: https://docs.oracle.com/javase/10/docs/api/java/sql/Statement.html#setQueryTimeout(int)

In source code on Apache Ignite JDBC Driver (https://apacheignite-sql.readme.io/docs/jdbc-driver) we can see that setting a query timeout not supported: https://github.com/apache/ignite/blob/master/modules/core/src/main/java/org/apache/ignite/internal/jdbc2/JdbcStatement.java

Hi
as far as I can tell there isn't a way to do this (Short of downloading and
modifying the source code)- You will have to raise an enhancmeent  for
JMeter (https://jmeter.apache.org/issues.html )

AbstractJDBCTestElement.java in source code can be modified if you want to
use -1 or equivalent to represent no timeout and not call the timeout method
