Patent number: 11940975Abstract: A computer-implemented method that includes receiving an ingestion request to ingest data to a database comprising physical shards and detecting that the ingestion request is directed to a first hotspot shard. The first hotspot shard has a contention level over a threshold value. The method also detects context characteristics within the data and generates a first virtual shard based on a first virtual shard key selected from the detected context characteristics. The first virtual shard virtually duplicates at least a portion of the first hotspot shard. The method also includes ingesting the data to the first virtual shard.Type: GrantFiled: September 28, 2020Date of Patent: March 26, 2024Assignee: International Business Machines CorporationInventors: Shuo Li, Peng Hui Jiang, Xiaobo Wang, Sheng Yan Sun

Patent number: 11914573Abstract: Disclosed are techniques for relational database locks based on columns. Database transactions may be targeted to specific columns of one or more records, instead of the entire row for those records, using primary keys.
