CONFIGURATION AND MANAGEMENT OF REPLICATION UNITS FOR ASYNCHRONOUS DATABASE TRANSACTION REPLICATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18372005 titled 'CONFIGURATION AND MANAGEMENT OF REPLICATION UNITS FOR ASYNCHRONOUS DATABASE TRANSACTION REPLICATION

Simplified Explanation

The abstract of the patent application describes a consensus protocol-based replication approach that optimizes replication efficiency by grouping chunks into replication units (RUs). These RUs can be split and merged without interrupting concurrent user workload or requiring routing changes. Each RU has a replication factor (RF) and a distribution factor (DF) to manage copies/replicas and workload distribution in case of server failures.

• Chunks are grouped into replication units (RUs) to optimize replication efficiency.
• RUs can be split and merged without interrupting user workload or requiring routing changes.
• Each RU has a replication factor (RF) and a distribution factor (DF) to manage copies and workload distribution.
• Transactions spanning chunks within an RU do not require distributed transaction processing.
• RUs may be placed in rings of servers, where the number of servers in a ring equals the replication factor.

Original Abstract Submitted

A consensus protocol-based replication approach is provided. Chunks are grouped into replication units (RUs) to optimize replication efficiency. Chunks may be assigned to RUs based on load and replication throughput. Splitting and merging RUs do not interrupt concurrent user workload or require routing changes. Transactions spanning chunks within an RU do not require distributed transaction processing. Each replication unit has a replication factor (RF), which refers to the number of copies/replicas of the replication unit, and an associated distribution factor (DF), which refers to the number of servers taking over the workload from a failed leader server. RUs may be placed in rings of servers, where the number of servers in a ring is equal to the replication factor, and quiescing the workload can be restricted to a ring of servers instead of the entire database.
