An example operation may include one or more of receiving, via a user interface, a feature set, querying a repository of application programming interfaces (APIs) to identify an API in the repository that corresponds to the received feature set based on a comparison of features in the feature set to features of the API stored in the repository, identifying criteria of the identified API that is published in the repository, and displaying a recommendation with the identified API including the identified criteria of the identified API via the user interface.

Apparatus, systems, and methods may operate to construct a memory barrier to protect a thread-specific use counter by serializing parallel instruction execution. If a reader thread is new and a writer thread is not waiting to access data to be read by the reader thread, the thread-specific use counter is created and associated with a read data structure and a write data structure. The thread-specific use counter may be incremented if a writer thread is not waiting. If the writer thread is waiting to access the data after the thread-specific use counter is created, then the thread-specific use counter is decremented without accessing the data by the reader thread. Otherwise, the data is accessed by the reader thread and then the thread-specific use counter is decremented. Additional apparatus, systems, and methods are disclosed.

Multithreaded lock management

Techniques for parallel processing of directory searches are provided. A directory search is received on a multicore or multiprocessor architecture machine. At least two threads processing on different cores or processors of the machine handle different aspects of the directory search. A first thread identifies matches in the directory for the search and serially populates the matches to search results. The second thread serially and in parallel grabs the matches in the search results and filters some out and modifies other ones of them to complete processing on the search. The search results are then returned to an initial requester making the initial search.

Techniques for enforcing access rights during directory access are presented. Access rights are maintained at the container level of a directory tree for container objects within a cache. When security is set for a requester of a target, the container object cache is directly accessed along with rights assigned to the target and the security is calculated and then set against the requester.

Selective durability in a directory database is presented. A directory database that provides durability processing includes a mechanism where selective attributes for directory resources can turn durability processing off. So, when a directory transaction is encountered having a durability processing turned off, the directory database processes that directory transaction without first flushing the directory transaction from memory to storage.

Proxy caching for directory services are presented. Requests for directory resources are intercepted and an inspection of cache is made to determine whether a resource being requested is identified in cache. When an identifier for the resource is identified in cache, a corresponding directory service associated with a cache entry for that resource is used to supply the resource; otherwise the resource is supplied by a directory service selected by policy.
