      The ace:dataTable component is a very complex component with several features that have to be integrated together in elaborate ways to make everything work as seamlessly as possible. Some of these features, such as sorting and filtering, require the underlying model to be rebuilt at certain stages during a request, in order for them to work correctly. More specifically, the getValue() method of the component has to be called multiple times during a request for different purposes. Typically, the model has to be rebuilt 3-6 times during a request, whether in lazy mode or not.

      Because, in lazy mode, loading data can be an expensive operation on some applications, it would be beneficial for many users if the ace:dataTable component was more efficient in calling LazyDataModel.load(), thus optimizing its performance. This could be accomplished via a built-in caching system and/or with better logic to avoid rebuilding the model in certain cases. The purpose of this JIRA is to investigate the possibility of improving data loading performance in lazy mode and implementing an optimization that is feasible if possible.
