) New client flags in reported by CLIENT INFO and CLIENT LIST: * `i` for atomic slot migration importing client * `E` for atomic slot migration exporting client New flags in return value of `ValkeyModule_GetContextFlags`: * `VALKEYMODULE_CTX_FLAGS_SLOT_IMPORT_CLIENT`: Indicate the that client attached to this context is the slot import client. * `VALKEYMODULE_CTX_FLAGS_SLOT_EXPORT_CLIENT`: Indicate the that client attached to this context is the slot export client. Users could use this to monitor the underlying client info of the slot migration, and more clearly understand why they see extra clients during the migration. Modules can use these to detect keyspace notifications on import clients. I am also adding export flags for symmetry, although there should not be keyspace notifications. But they would potentially be visible in command filters or in server events triggered by that client. --------- Signed-off-by: Jacob Murphy <[email protected]>
