The server_logging extension makes the logger include the server/shard the query was issued on. This makes it easier to use the logs when using sharding.
Example:
DB.opts[:server] # {:read_only=>{}, :b=>{}} DB.extension :server_logging DB[:a].all # (0.000005s) (conn: 1014942550, server: read_only) SELECT * FROM a DB[:a].server(:b).all # (0.000004s) (conn: 997304100, server: b) SELECT * FROM a DB[:a].insert # (0.000004s) (conn: 1014374750, server: default) INSERT INTO a DEFAULT VALUES
In order for the server/shard to be correct for all connections, you need to use this before connections to the database are made, or you need to call Database#disconnect after loading this extension.
