There’s no special way to retrieve a large result set; this can be done the same as any other database query via JDBC.
The key is in how the results are handled. 140,000 small records is not too many, but if holding them all in application memory at once is a problem, consider whether they can be processed “streamwise”. That is, use the information needed from each record, then discard the record before retrieving the next. This way, the memory requirement doesn’t depend on the number of records in the result set.
