maxTotalConnections
maxTotalConnections is a configuration parameter used by resource connection pools to bound the total number of connections that can be open to a resource, such as a database or a remote service. It defines the ceiling for both currently active connections and idle connections that the pool may maintain at any given time. The exact naming and semantics can vary by library; some implementations call it maxTotal, maximumPoolSize, or similar.
In practice, maxTotalConnections controls the pool size. The pool may recycle and reuse connections, but once
Choosing a value involves trade-offs. A higher limit can improve throughput under heavy load but risks exhausting
Operational considerations include monitoring active and idle connections, wait times, and queue lengths. Start with a
