Abstract: Techniques are disclosed relating to an in-memory cache for web application data. In some embodiments, received transactions include multiple operations, including one or more cache operations to access the in-memory cache. In some embodiments, transactions are performed atomically. In some embodiments, data for the one or more cache operations is stored locally in memory by an application server outside of the in-memory cache until the transaction is successfully completed. This may improve performance and facilitate atomicity, in some embodiments.

Abstract: Techniques are disclosed relating to an in-memory, software-managed cache configured to store web application data. In some embodiments, operations to cache data specify a visibility parameter for the data, among a plurality of namespaces. In some embodiments, requests to access cached data are checked, based on a request's namespace and the visibility parameter for the cached data, to determine whether they are allowed to proceed. In some embodiments, this may facilitate caching data using shared computing systems and data structures while maintaining configurable privacy for cached data.

Abstract: Techniques are disclosed relating to an in-memory cache. In some embodiments, in response to determining that data for a requested entry is not present in the cache (e.g., because it has been evicted), a computing system is configured to invoke cached program code associated with the entry. In some embodiments, the computing system is configured to provide data generated by the program code in response to requests that indicate the entry. In some embodiments, the computing system is configured to store the generated data in the cache. In various embodiments, this may avoid cache misses and provide configurability in responding to requests to access the cache.

Abstract: Techniques are disclosed relating to caching web application data. In some embodiments, a computing system maintains a multi-tenant database and an in-memory cache for the database. In some embodiments, the computing system is configured to store data in an entry in response to a store request and retrieve data in response to a read request. In various embodiments, data cached by one tenant is not visible to other tenants. The cache may be partitioned and each partition may have an assigned capacity. The computing system may be configured to evict cached data based on capacity thresholds, least-recently-used information, time-to-live information, amount of data in an entry, etc. The cache may indicate misses when requested data is not present. Various disclosed techniques may improve web application performance while maintaining privacy between tenants.
