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. Column locks on specific keys are stored separately than column locks on ranges of keys, which are both checked when requesting a new column lock for either a single key or a range of keys. When a threshold number of columns for a given record, or range of records/keys, have been locked, the column locks for that record, or range of records, can be combined into a single row level lock to reduce resource costs for maintaining multiple concurrent locks.Type: GrantFiled: March 23, 2022Date of Patent: February 27, 2024Assignee: International Business Machines CorporationInventors: Shuo Li, Xiaobo Wang, Hong Mei Zhang, Sheng Yan Sun

Publication number: 20240045878Abstract: Provided are techniques for building and using a sparse Time Series Database (TSDB). Time series records are received from a native TSDB, where each of the time series records includes a timestamp and one or more tags. Timeslots are determined for shards for the sparse TSDB based on the timestamp included in each of the time series records. The sparse TSDB is built by creating the shards for the determined timeslots and storing the time series records in the shards, while filling in empty ranges in the shards. A query that specifies at least one of the one or more tags is received. It is determined whether to execute the query against the sparse TSDB, and, in response to a determination to execute the query against the sparse TSDB, the query is executed against the sparse TSDB to generate results that are returned.Type: ApplicationFiled: August 5, 2022Publication date: February 8, 2024Inventors: Peng Hui JIANG, Jun SU, Sheng Yan SUN, Hong Mei ZHANG, Meng WAN
