Description
Nhat has a POC for CachedDirectoryReader that seems to improve Lookup Join performance. The optimization seems universal and not tied to a particular case. We would like to convert this POC into a feature and deliver it to our customers, so they can take advantage of the optimization.
The optimization has two parts.
Caching docValues and caching termsEnum.
This epic will track our work for Caching docValues. The work for caching termsEnum will be tracked by #139407.
