------------------------------------
Summary: Optimize BatchTranslator - use fixed size array of
BatchParameterBinding
Key: CAY-1923
URL: https://issues.apache.org/jira/browse/CAY-1923
Project: Cayenne
Issue Type: Bug
Reporter: Andrus Adamchik
Assignee: Andrus Adamchik
Fix For: 3.2.M2
The new BatchTranslator has this method:
List<BatchParameterBinding> createBindings(BatchQueryRow row);
The list contents differ from row to row (e.g. due to NULL handling). This
creates an inefficiency in the default mode of operation (List and
BatchParameterBinding are created over and over again in the same tx), and
makes crypto interception doubly inefficient, as we'll need to compile
encryptors for each row individually. So need to batch this somehow. E.g. by
allocating a single BatchParameterBinding[], filling it with bindings and then
reusing it for each row. Excluded bindings for a given row will be marked with
some flag. This will also allow to precompile encryptors in the crypto module.
