Abstract: Embodiments of the present invention disclose a data index query method including: after performing Gray encoding on an index attribute, shuffling and encoding, by a server side, a Gray code corresponding to the index attribute to generate at least one index key value and storing the index key value; generating, by the server side according to query condition information carried in a query request, an index key value set or interval corresponding to the query condition information; obtaining an indicator set or interval used for indicating data and corresponding to the index key value set or interval according to the index key value set or interval; generating an intermediate data set corresponding to the indicator set or interval; and finally obtaining, from the intermediate data set, a target data set corresponding to the query condition information according to the query condition information carried in the query request.

Abstract translation: 本发明的实施例公开了一种数据索引查询方法，包括：在对服务器侧的索引属性，混洗和编码执行Gray编码之后，对应于索引属性的格雷码，生成至少一个索引关键字值，并存储 索引值; 根据查询请求中携带的查询条件信息，由服务器侧生成与查询条件信息对应的索引关键字值集合或间隔; 根据索引关键字值或间隔，获得指标数据，用于指示数据并对应于索引关键字值集或间隔; 生成对应于指示符集或间隔的中间数据集; 最后根据查询请求中携带的查询条件信息从中间数据集中获取与查询条件信息对应的目标数据集。

Abstract: A method and an apparatus for accessing a critical resource, a computer device, and a readable storage medium are provided, to help reduce a quantity of operations for contending for a lock by a thread, and computing resources, and improve performance of an ARM processor. The method for accessing a critical resource includes: selecting a first thread from the first thread and a second thread to contend for a target lock (201), where a first task to be executed by the first thread and a second task to be executed by the second thread correspond to the target lock; and if the first thread obtains the target lock through contention, enabling the first thread to execute the first task, and replace the second thread to execute the second task (202).

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.
