  • Time series data injection method, time series data query method, and database system
    Patent number: 12204534
    Abstract: A time series data injection method is provided, including: receiving time series data, where the time series data includes at least one parameter identifying a data source that generates the time series data, an indicator indicating at least one attribute of the data source, and a timestamp indicating a time point when the indicator is generated; storing a first parameter group in a row storage format, where the first parameter group includes the at least one parameter identifying the data source that generates the time series data; and storing a second parameter group in a columnar storage format, where the second parameter group includes the indicator indicating the at least one attribute of the data source and the timestamp. In the method, the time series data is injected in a hybrid row-column storage manner.
