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 20240126782 titled 'CONFIGURATION AND MANAGEMENT OF REPLICATION UNITS FOR ASYNCHRONOUS DATABASE TRANSACTION REPLICATION

Simplified Explanation

A consensus protocol-based replication approach is provided in this patent application. 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) and an associated distribution factor (DF). 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.

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.
