CONCURRENT AND NON-BLOCKING OBJECT DELETION FOR CROSS-REGION REPLICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18521176 titled 'CONCURRENT AND NON-BLOCKING OBJECT DELETION FOR CROSS-REGION REPLICATIONS

Simplified Explanation

The patent application describes techniques for enabling concurrent and non-blocking replication object deletion during cross-region replications. In some embodiments, a target replication pipeline and a deletion pipeline operate in parallel in a target file system during cross-region replication. The deletion pipeline deletes processed objects after each checkpoint in the target replication pipeline, allowing for a fresh restart of the replication in case of non-recoverable failure without waiting for unused objects to be deleted. This is achieved by utilizing a generation number associated with each object to delete unused objects in the background while allowing the deletion of processed objects as normal for the freshly restarted replication.

• Techniques for concurrent and non-blocking replication object deletion during cross-region replications
• Target replication pipeline and deletion pipeline operating in parallel

How does this technology impact data security during cross-region replications?

The article does not specifically address the impact of this technology on data security during cross-region replications. It would be important to understand how the deletion process affects the overall security of the replicated data.

What are the scalability limitations of this technology in large-scale replication scenarios?

The article does not delve into the scalability limitations of this technology in large-scale replication scenarios. It would be crucial to know how well this approach performs when dealing with a massive amount of data in cross-region replications.

Original Abstract Submitted

Techniques are described for enabling concurrent and non-blocking replication object deletion during cross-region replications. In some embodiments, in a target file system, a target replication pipeline as part of a cross-region replication, and a deletion pipeline operate in parallel. The deletion pipeline deletes processed objects reaching the last pipeline stage of the target replication pipeline after each checkpoint in the target replication pipeline. In some embodiments, after a non-recoverable failure during the cross-region replication, the cross-region replication can be restarted from the beginning (i.e., fresh restart) without waiting for its unused objects in the Object Store to be deleted by utilizing a generation number associated with each object to delete the unused objects in a background process while allowing deleting processed objects as normal for the freshly restarted cross-region replication.
