Resolution: Fixed
> 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
> means we need to create a new List and new BatchParameterBindings, which
> results in an inefficiency in the default mode of operation. This also makes
> crypto-related 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.
