> h5.Background
> Existing implementation of Export API w.r.t ZIP file generation adds 1
> *.json* file per entity. This makes ZIP file creation inefficient. The ZIP
> files are 75% larger in size than what could be possible with fewer *.json*
> file entries.
> h5.Solution
> The implementation uses the new v2 API *AtlasEntityWithExtInfo*
> representation instead of *AtlasEntity*. This format combines an entity with
> related entities as one. E.g. *hive_table* will contain all the
> *hive_columns* that it is made up of. (See example section below.)
> This results in significant reduction of generated *JSON* files. This impacts
> reduction in generated *ZIP* file.
