Execute multiple queries simultaneously on a single session

Hey,

i noticed that JDBC Connection can execute only one statement in parallel. the second statement is executed once the first one ended.

i assume that the JDBC connection has a single session_id in Vertica, so my quetions are:

1. is it possible in Vertica to execute multiple queries on a single session in parallel?

2. can there be a situation in which the SESSIONS table contains several transaction per one session?

thanks,

Asher
