These are 2 new sample fetches which provide the available connections. The be_conn_free fetch is similar to connslots, but has significant difference in that it does not count queue slots, nor backup servers (unless all servers are down).
These are intended to be useful in combination with the priority queuing, so you can see how many connections are available, perhaps for taking action when the number is low. For example by reserving connections for high-priority requests, and rejecting low priority ones. -Patrick Patrick Hemmer (2): MINOR: add be_conn_free sample fetch MINOR: Add srv_conn_free sample fetch doc/configuration.txt | 34 +++++++++++++++++++++--- src/backend.c | 60 +++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 91 insertions(+), 3 deletions(-) -- 2.18.0
