The present invention enables separate authorization of the operation permissions for the statistical data in the statistical list according to the column values; one statistical list can meet different actual usage requirements after the authorization of different statistical data operation permissions.

Abstract: Example methods and apparatuses for file compaction in a key-value store system relating to the field of data processing technologies are described. One example method for file compaction in a key-value store (KV-Store) system includes compacting, according to a to-be-deleted log (Delete Log) that corresponds to a to-be-compacted sorted string table (SSTable), the to-be-compacted SSTable to generate a new SSTable. A key corresponding to a non-latest value in the KV-Store system and stored in the to-be-compacted SSTable is recorded in the Delete Log, and the new SSTable does not include a key-value pair that corresponds to the key in Delete Log. The to-be-compacted SSTable is then deleted.
