Solace’s message caching solution, called SolCache, enables the storage of data sent as part of a high-performance messaging stream in memory for low latency retrieval of data. Access to this message caching capability is integrated into the Solace API, enabling sophisticated lookups and operation.
- High performance: A single instance of SolCache supports up to 70,000 lookups per second and can cache 500,000 messages per second. (100 byte messages)
- Scalability: SolCache can be distributed across servers to scale as your rates and topic space grows without affecting applications using the cache.
- Overlap handling: SolCache lets developers determine how to deal with data that arrives while a cache request is outstanding. The live data can fulfill the cache request, be delivered to the application after the cache response, or be delivered to the application immediately followed by the cache response when it arrives.
- Global Caching: When a client application requests a cached entry for an object from its local SolCache and this object is published from a remote location and not currently cached by the local SolCache, the local SolCache will automatically retrieve it from the remote SolCache and cache it, along with its updates locally, to service subsequent client requests.
- Incremental Updates: SolCache supports user plug-ins which allow messages to be interpreted before applying them to images stored in SolCache. For example, if a feed handler sends out delta updates to a security or book, a SolCache user plug-ins could process them and do something like overwrite the last bid or ask fields, or keep a cumulative value for trade volume.
