This method makes data recovery and query more convenient while saving storage space, as it is generally not necessary to store the complete data of all historical periods. Moreover, by using snapshot files, consistent and integral control over data can be achieved, ensuring the accuracy and correctness of the data within each period."}]}],"pr":"1461394398fc6949f7b2bb8e8b9371600331a50221cb2e72f066b087f5c57df7"}
