java/kudu-client/src/main/java/org/apache/kudu/client/AsyncKuduSession.java:

Line 213:    * Sets the maximum capacity of this session's ErrorCollector.

I can see the argument for both size-based and count-based capacity.

We used sized-based capacity in the C++ client at the request of Impala, who 
wanted to upper bound the memory consumption of a particular query against 
Kudu. Writ large, I think size-based capacity makes sense when the user of the 
client is an application.

On the other hand, as Eric points out, count-based capacity can be useful when 
the user of the client is a user who expects to interact directly with errors 
rather than adapting them into something else.

Another option is to implement both approaches and consider either bound when 
collecting a new error. What do you guys think?
