Compression Support for Cloud File Servers
The file servers Amazon S3, Google cloud storage, and MS Azure Blobstore support the
compressed formats gzip (.gz) and zip (.zip).
The Spectrum™ Technology Platform handles the compression and decompression of the
files written to and read from the file servers.
Note: You can use the same file server to
handle both normal reads and writes of files as well as compression and decompression of
files.
Reading a Compressed Format File
While reading a file from the server, its compression format is derived from the metadata key propertyContent-Encoding received from the server.Writing a Compressed Format File
While writing a file to a server, mention the required compression format:.gz or .zip. The
file is compressed based on the specified compression extension. The metadata key
property Content-Encoding is also set according to the selected compression
format. This property value is passed to the cloud file server while writing the file to
it.
