Caches for Internal Entities
Specific internal caches use a pre-defined scheme in the cache configuration file.
Do not change this scheme. This information is provided for reference only.
Entity (Cache) name | Purpose of the Cache |
---|---|
Master |
Maintains the cluster state and is shared by all nodes. |
Catalog |
Maintains a cached copy of all ontology definitions shared by all nodes. |
TypeIDs |
TypeIDs are internal numbers used to store the short number to identify the URL of a concept instead the large string. |
ObjectTableIDs |
Stores the key mapping for all objects in the cluster. The objects themselves are stored in their respective caches. |
ObjectTableExtIDs |
Stores the external key mapping for all objects that have an external ID (extId). |
AgentTable |
Stores all the agents and their respective states across all cluster nodes and identifies the currently active and standby nodes. |
AgentTxn-agentId |
Each agent in the cluster has an AgentTxn-agentId cache. The agentId is internally generated. It stores the change list for the agent. The change list is used to replicate changes between active-active and active-passive sets of agents in the cluster so that they stay synchronized. |
TimeQueue |
Maintains all entries that are time bound, for example, state machines that can have timeouts at a state machine level or at a state level. This cache maintains an index to all objects that must be re-evaluated after a certain period of time. |
