      Description

      Currently, command execution allows only a single subscription from a Flux/Mono:

      Mono<Long> foo = redisOperations.delete("foo");
      foo.subscribe(); // completes normally
      foo.subscribe(); // fails because of closed connection
      

      Template API calls assemble publishers that pre-allocate connections and operate on that particular connection. Once the first subscription terminates, the collection is returned and no longer usable for subsequent subscriptions.

      Publishers without a subscription stay with the allocated connection which causes a resource leak because the associated connection is never released.

      On a different note: Connections are allocated through a synchronous API which may incur blocking.
