Query Language
JDBC V1 is similar in its performance and its coverage to the GigaSpaces API and is used only in our Smart Cache solution.
JDBC V3 has full ANSI-SQL coverage,however it is more complex but the performance of simple queries will be slightly less than JDBC V1.
In addition, JDBC V3 has support for ODBC and JDBC Postgress flavors.
