com.google.appengine.api.datastore.DatastoreServiceConfig.maxEntityGroupsPerRpc()

Sets the maximum number of entity groups that can be represented in a single rpc. For a non-transactional operation that involves more entity groups than the maximum, the operation will be performed by executing multiple, asynchronous rpcs to the datastore, each of which has no more entity groups represented than the maximum. So, if a put() operation has 8 entity groups and the maximum is 3, we will send 3 rpcs, 2 with 3 entity groups and 1 with 2 entity groups. This is a performance optimization - in many cases multiple, small, asynchronous rpcs will finish faster than a single large asynchronous rpc. The optimal value for this property will be application-specific, so experimentation is encouraged. @param maxEntityGroupsPerRpc the maximum number of entity groups per rpc @throws IllegalArgumentException if maxEntityGroupsPerRpc is not greaterthan zero @return {@code this} (for chaining)
