Implementing a naming service for a hierarchal namespace in a database format. A method includes at a database, wherein the database stores a first table having references to hierarchical nodes in a hierarchical namespace, and a second table with relational references to hierarchical nodes referenced in the first table, detecting an edge modification event changing one or more edges of a node in the hierarchical namespace. The method further includes, as a result, creating a unique row in the second table for the edge modification event in the hierarchical namespace. Any edge modification event results in creation of a unique row in the second table such that different entities can cause overlapping edge modification events that can be documented at the database without transactional conflicts.

High-performance naming service using an optimistic-concurrency-control in-memory database

A naming service for a hierarchical namespace. The naming service includes a database system with a first table having first records. Each of the first records is for a hierarchical node and includes a node identifier and an ACL identifier to a set of access control rules applicable to the node. The database system includes a second table including second records, each record in the second records has one of the ACL identifiers from the first table correlated with a definition access control rules in the set of access control rules. The naming service includes an access control rule identifier generator configured to detect a set of access control rules for each node in the namespace and generate an a ACL identifier for each set of access control rules that can be stored in records in the first table and stored in records in the second table.
