Abstract: A global secondary index method for a distributed database, includes: obtaining original data to be written in response to a database writing request; writing the original data into the distributed database; performing global secondary index processing on the original data written into the distributed database to obtain global secondary index data; establishing global secondary index tables between the global secondary index data and data table primary keys in the distributed database; and writing the global secondary index tables into an index shards based on an asynchronous processing manner.
