Abstract
Technologies are described for managing shared read-only objects in hybrid distributed database systems. For example, data structures can be maintained for managing the shared read-only objects, comprising a data structure storing a “deleted at” value for each shared read-only object, a data structure storing a “deleted at” value for each secondary node, a data structure storing a indication of which secondary nodes are reading which shared read-only objects, and a data structure storing a reference count indicating a number of active read transactions for each shared read-only object. The shared read-only objects that can be garbage collected can be identified using, at least in part, the data structures. The identified shared read-only objects can then be garbage collected.
