Spark Connector Read

Since we are limited how many connections we can make as a client, the reader has this error: java.sql.SQLNonTransientConnectionException: [Vertica]VJDBC FATAL: New session rejected because connection limit of 16 on database already met for M21176
at com.vertica.util.ServerErrorData.buildException(Unknown Source)

We don't know how many the reader really needs, sometimes it is only 1, sometimes it needs many, how we avoid this exception (lift the the limit 16 is not an option for us).
