Module pool

Modules§

ActiveSlot: Active slot is able to actively use a connection to make requests. They are used to track ‘active’ connections inside the pool
LeasedConnection: LeasedConnection is a connection that is temporarily leased from a pool
LruDropPool: Connection pool that uses LRU to evict connections
NoPool: Connection pool that doesn’t store connections and has no limits.
PoolSlot: Pool slot is needed to add a connection to the pool. Poolslots have a one to one mapping to connections inside the pool, and are used to track the ‘total’ connections inside the pool

ConnID: ConnID is used to identify a connection in a connection pool. These IDs are not unique and multiple connections can have the same ID. IDs are used to filter which connections can be used for a specific Request in a way that is independent of what a Request is.
Pool: [PoolStorage] implements the storage part of a connection pool. This storage also decides which connection it returns for a given ID or when the caller asks to remove one, this results in the storage deciding which mode we use for connection reuse and dropping (eg FIFO for reuse and LRU for dropping conn when pool is full)
ReqToConnID: ReqToConnID is used to convert a Request to a connection ID. These IDs are not unique and multiple connections can have the same ID. IDs are used to filter which connections can be used for a specific Request in a way that is independent of what a Request is.
