Log data query method and device, equipment and medium

The invention relates to a log data query method and device, equipment and a medium, and belongs to the technical field of cloud. The method comprises the following steps: determining a target node matched with a query time range from a log query time tree; each node in the log query time tree records a time range of log query; the time range recorded by the target node intersects with the query time range; determining a target sub-tree from the sub-trees under the target node; performing leaf node traversal processing from an edge leaf node of the target sub-tree, and stopping traversal after a target leaf node is traversed; corresponding log data exists in a disk in a time value within a target time range recorded in the target leaf node; determining a time value which corresponds to log data and is in a critical state and is recorded by the target leaf node, and obtaining a boundary time value corresponding to the query time range; and obtaining log data matched with the query time range from the disk acco
