Teiid Spring Boot separates the configuration of its socket transports for JDBC and pg/ODBC. You have the option of also configuring secure versions of these transports. Typical installations will not need to adjust the default thread and other low level settings.
JDBC clients may need to adjust low-level transport values, in addition to SSL Client Connection properties via a teiid-client-settings.properties file. This file also contains buffer, socket pooling, and maxObjectSize (effectively the maximum response size) settings.
