Writing an object

Writing an Object to PSS works exactly like FSS. Writes are completed in three phases: write, commit, and finalize.

Write

Slice data is written to disk. The slice is now durable, but cannot be read back until it is committed.

Commit

Data is made visible to client systems or APIs. An attempt to access this object will succeed. The commit phase starts once slices are written to a number of IBM Cloud Object Storage Slicestor® nodes equal to the IDA Write Threshold.

Finalize

If the object being written is an update of an existing object, the previous revision of the data is removed from the system when it is finalized. The finalize phase starts once slices have been committed to a number of IBM Cloud Object Storage Slicestor® nodes equal to the IDA Write Threshold.
