I cannot understand why the SQLImporter waits so long before starting importing data: between 10 and 40 minutes.
This is an example of data ingesting:
java -cp /opt/mapd/mapd-ce-3.1.1/bin/mapd-1.0-SNAPSHOT-jar-with-dependencies.jar:/opt/jdbc_driver/MySql/mysql-connector-java-5.1.39/mysql-connector-java-5.1.39-bin.jar com.mapd.utility.SQLImporter -t <tablename> -sp ... -su ... -c jdbc:mysql://servername:3306/databasename -ss "select * from <tablename>"
2017-07-06 15:36:09 INFO SQLImporter:executeQuery:188 - Connecting to database url :jdbc:mysql://servername:3306/databasename
Thu Jul 06 15:36:10 CEST 2017 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
I have about 25 millions rows in the table to be imported: after a while, the import begins and it is fine.
