Abstract: The present disclosure provides a method and apparatus for writing data in an append mode, a device and a storage medium. The present disclosure relates to the field of cloud storage technology, and can be applied to a cloud platform. The method includes: acquiring to-be-written data, and writing the to-be-written data into a magnetic disk; writing first index information of the to-be-written data in a memory; storing, in response to determining that the number of pieces of second index information is greater than a first preset threshold, the second index information into storage hardware, the second index information including the first index information; and writing first identifier information corresponding to the second index information in the memory.

Abstract: The present disclosure provides a data reading method, including: in response to receiving a read response request generated by a replication group for an application and sent by a storage terminal, setting, in a dedicated mapping table corresponding to the application, a commit index corresponding to the replication group as a commit index carried by the read response request; searching for a target replication group corresponding to a first read request generated by a target application based on the first read request; determining, in a dedicated mapping table corresponding to the target application, a commit index corresponding to the target replication group as a target commit index; sending a second read request carrying the target commit index to the storage terminal; and obtaining the data read by the storage terminal.
