Feature storage method and device, feature reading method and device, medium, equipment and product

The invention relates to a feature storage method and device, a feature reading method and device, a medium, equipment and a product. The method comprises the steps that in response to a monitored storage request for feature data of a first feature, a target feature group to which the first feature belongs is determined in multiple feature groups, and each feature group comprises multiple preset features; obtaining feature data of a second feature, wherein the second feature comprises other preset features except the first feature in the target feature group; compressing the feature data of the first feature and the feature data of the second feature to obtain feature group compressed data corresponding to the target feature group; and writing the feature group compressed data into a preset database corresponding to the target feature group. Therefore, the compression ratio of the features is improved, and the pressure of feature storage is effectively reduced. 本公开涉及一种特征存储方法、特征读取方法、装置、介质、设备及产品。所述方法包括：响应于监听到针对
