Client Supported MEPs

Configuring the Maximum Message Size for the gRPC Service

In MEP 6.3.4 and later, the Java OJAI Thin Client supports an OJAI Connection String option (maxmsgsize) to change the maximum message size that the gRPC client accepts. For details, see Using the Java OJAI Thin Client.
