Chetan Mehrotra resolved OAK-1655.
----------------------------------

    Resolution: Fixed

bq. The GarbageCollectableBlobStore.deleteChunks also has a maxLastModifiedTime 
parameter. If deleteChunks is implemented correctly (and called correctly), 
then new binaries should not be deleted. So I don't think this TODO will cause 
trouble for garbage collection.

Missed that part. We should be safe then. 

Fixed in http://svn.apache.org/r1583594

> DataStoreBlobStore does not take into maxLastModifiedTime when fetching all

> Currently the {{DataStoreBlobStore}} has a pending TODO
> {code}
>  @Override
>     public Iterator<String> getAllChunkIds(long maxLastModifiedTime) throws 
> Exception {
>         //TODO Ignores the maxLastModifiedTime currently.
>         return Iterators.transform(delegate.getAllIdentifiers(), new 
> Function<DataIdentifier, String>() {
>             @Nullable
>             @Override
>             public String apply(@Nullable DataIdentifier input) {
>                 return input.toString();
>             }
>         });

> {code}
> Due to this it currently returns all blobId. This would issue when new binary 
> gets created while a blob gc is running as such binaries might be considered 
> orphan and deleted
