Title:
HIGH-THROUGHPUT DISTRIBUTED TRANSACTION MANAGEMENT FOR GLOBALLY CONSISTENT SHARDED OLTP SYSTEM AND METHOD OF IMPLEMENTING
Document Type and Number:
WIPO Patent Application WO/2019/109853
Kind Code:
A1
Abstract:
A system and method for improved online transaction processing (OLTP) in a sharded database is provided. Overhead associated with a global transaction manager is reduced and scalability improved by determining whether incoming queries are single-shard transactions or multi-shard transactions. For multi-shard transactions, a distributed transaction ID (DXID) is requested from the GTM, and then forwarded with the query to one or more data notes. For single-shard transactions, the query is sent to a data node without requesting a DXID from the GTM.
