Data query method and device, electronic equipment and storage medium

The invention relates to the technical field of computers, in particular to a data query method and device, electronic equipment and a storage medium, and is used for improving data query efficiency. The method comprises the steps of obtaining multiple pieces of target log data screened from log data contained in a log data set, determining at least two endpoint timestamps according to a to-be-queried time interval, and determining endpoint log data corresponding to the at least two endpoint timestamps from the multiple pieces of target log data; and determining at least one log data subset of the to-be-queried time interval based on each piece of endpoint log data, and determining log data subsets to which other target log data belong based on identification information of other target log data except each piece of endpoint log data. As the log data in the log data set are sorted in advance according to the size of the timestamps, the target log data contained in the to-be-queried time interval can be obtain
