Client Supported EEPs
MapR Database JSON REST API EEP 5.0.0 and later

Configuring the Maximum Message Size for the gRPC Service

EEP 6.3.4 and later support a new configuration option (grpc.service.max-message-size) that allows you to change the maximum message size that the gRPC service accepts. For details, see Administering the MapR Data Access Gateway.

In EEP 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.
