IN-MEMORY WORKSPACE MANAGEMENT

摘要

In in-memory workspace management, a request is received from a user to open a document. It is determined whether the document is opened. Upon determining that the document is already opened, an existing workspace instance corresponding to the opened document is shared with the user. A mapping between the workspace request identifier and a workspace identifier is maintained in a workspace map. A reference count mapped to the workspace identifier is incremented since the existing workspace instance is shared with the user. It is determined whether the document is edited. The shared workspace instance is discontinued from sharing and is forked to create a new workspace instance for editing. The mapping between workspace request identifier and workspace identifier is removed from the workspace map. The reference count map is updated to decrement the reference count corresponding to the workspace identifier.
