>
> In lazy caching, AsterixDB won't download any of the indexes data and
> metadata files. However, when activating an index, the index files will be
> downloaded. However, the download is single-threaded and the index activation
> is not concurrent. Meaning, a node can only activate a single index at a
> time, during which a single file is downloaded at a time for the same index.
