Question:
What is "To set a C3P0 pooling property" of ”Additional Properties" of "JDBC Connection properties"?
Waht is  the behavior when 'To set a C3P 0 pooling property' is not checked?
Environment:
API Gateway
Answer:

C3P0 is a JDBC connection pooling library. 
Use this 3rd party library in Gateway for connection pooling.

If wants to pass any additional properties to pooling, should check the C3P0 pooling property check box.

If "To set a C3P0 pooling property" is not checked, that property is not enabled.
In that case, the default value of C3P0 is enabled.
