BlobInfo indexes has too much capacity

BlobInfo indexes has too much capacity.

see your Datastore Statistics of BlobInfo

https://appengine.google.com/datastore/statistics?app_id=s~<your_app_id>&kind=__BlobInfo__

Size of __BlobInfo__ in my case:

|             |Entites  |Built-in Indexes
|Total Size:  |12 MBytes|89 MBytes
|Entry count: |13,656   |204,840
|Average Size:|888 Bytes|458 Bytes

BlobInfo total size is 12 MBytes, but index total size is 89 MBytes!!! Wow…

May have been using these indexes for `Filter blobs by:` pulldown in Blob Viewer.

But these indexes are unnecessary for me.

Please tell me how to suppress the creation of the BlobInfo indexes.

Thanks.
