Interception of database queries for delegation to an in memory data grid

A method for use with a client database driver that selectively forwards incoming database queries to one of the following recipient components:

• a database or an in memory data grid, the method comprising:
• receiving, by the client database driver, a grid eligible query type data set including information indicative of query types that are eligible to be sent to the in memory data grid instead of to the database;
• receiving, by the client database driver, a new database query;
• determining, by the client database driver and based upon the grid eligible query type data set, that the new database query is of a query type such that the new database query is a grid-eligible database query that is eligible to be sent to the in memory data grid;
• responsive to the determination that the new database query is a grid-eligible query, determining, by the client database driver, a utilization level value of the in memory data grid;
• comparing, by the client database driver, the utilization level value of the in memory data grid to a predetermined threshold value to determine that the utilization level value is higher than the predetermined threshold value;
• and
• responsive to the determination that the utilization level value is higher than the threshold value, forwarding, by the client database driver, the grid-eligible database query to the database instead of to the in memory data grid.
