/* * SchemaCloudDictionaryCache provides a local cache for SchemaCloudDictionary. * * Caching logic: * - If the dictionary associated with a given key has not had any new columns added * (determined by comparing the serialized data for consistency), * the cached dictionary is directly used to update the dictionary list in the rowset meta * (similar to the process_dictionary logic in write_schema_dict). * - If new columns have been detected, the local cache is disregarded, and the updated * dictionary should be fetched via the meta service. */ use SchemaCloudDictionaryCache in Backend to reduce the frequency of reading and converting SchemaCloudDictionary in MetaService ### What problem does this PR solve?
