Is your feature request related to a problem? Please describe.

I have a use case that necessitates using the Storage/Bucket write method variants with InputStream arguments. The inputs for my use case to store in Cloud Storage are:

  • predominantly already compressed,
  • have a wide range of file sizes, from a few KB to GB+,
  • we don't always know the size in advance.

Describe the solution you'd like

Given that our content is already compressed, I would prefer to avoid spending the CPU time on compressing the content again en route to the Bucket.

Describe alternatives you've considered

We have used the byte[] variants, with BlobTargetOption.disableGzipContent and the Compose request. This is suitable but leaves us with a tuning challenge:

  • Buffering these streams into memory (byte[] chunks) requires additional heap space be available
  • Compose is limited to only 32 chunks. If the file content we intend to store is far larger than 32 * bufferSize, we will upload 31 small sized chunks and 1 large chunk that we have to use the InputStream variant for anyways, and pay the additional overhead of gzip compression.

Additional context

I have done some exploration and it appears that the values on the BlobWriteOption (used on InputStream variants) and BlobTargetOption (used on byte[] variants) enums both are translated into StorageRpc.Option. I have a small contribution to offer in the form of a pull request to follow.

Just saw the project has relocated - I'll take a look at porting the changes over to this new project.

Previously, only the methods to create blobs that take a byte[] argument offer the option to disable gzip compression; the methods that accept an InputStream argument do not. This is due to the BlobWriteOption enum missing a matching constant for BlobTargetOption.IF_DISABLE_GZIP_CONTENT.

This change set adds a matching IF_DISABLE_GZIP_CONTENT constant to BlobWriteOption including the correct translation to StorageRpc.Option. The net result is that the Storage create functions that accept an InputStream now offer the option to disable gzip compression.
