摘要：【中文】一种写数据方法、装置及存储节点，涉及存储技术领域，能够解决在写请求的数量较小的情况下，聚合时延较大的问题。该写数据方法应用于分布式存储系统中的存储节点。存储节点确定第一并发数和第二并发数，第一并发数为聚合队列中在第一预设时间段的单位时间内并发写请求的数量，第二并发数为聚合队列中在第二预设时间段的单位时间内并发写请求的数量。若第一并发数和第二并发数之间的差值小于或等于预设数值，则存储节点根据第一并发数和第二并发数，计算得到目标并发数，并根据目标并发数，聚合聚合队列中写请求的数据，以及将聚合后的数据写入分布式缓存资源池。 【EN】A data writing method, a data writing device and a storage node relate to the technical field of storage and can solve the problem that aggregation time delay is large under the condition that the number of writing requests is small. The data writing method is applied to storage nodes in the distributed storage system. The storage node determines a first concurrency number and a second concurrency number, wherein the first concurrency number is the number of concurrent write requests in the aggregation queue within a unit time of a first preset time period, and the second concurrency number is the number of concurrent write requests in the aggregation queue within a unit time of a second preset time period. If the difference value between the first concurrency number and the second concurrency number is smaller than or equal to a preset numerical value, the storage node calculates to obtain a target concurrency number according to the first concurrency number and the second concurrency number, aggregates the data of the write request in the aggregation queue according to the target concurrency number, and writes the aggregated data into the distributed cache resource pool.
