Postgres tuning max_connections 是指对PostgreSQL数据库中的max_connections参数进行调优。 max_connections参数是指允许同时连接到PostgreSQL数据库的最大客户端连接数。通过调整这个参数,可以控制数据库的并发连接数,从而影响数据库的性能和可扩展性。 在进行max_connections参数调优时,需要考虑以下几个方面: 硬件资源:max...

illustrating the cost of establishing connections. I then configured pgbouncer withmax_client_conn = 10000,max_db_connections = 300,pool_mode = transaction, and ran the same pgbench tests again, using the pgbouncer port instead (-h <hostname> -p6432 -U postgres --client=<num_c...
Before 2.1.0, we were setting max_connections, max_worker_processes and some other config params to match the source (primary), looking at pg_controldata. Example:
Could you check what is your thread-pool-size in domain.xml? The default value of max-thread-pool-size is 200. If it is set to a low value, you might see only those number of active connections to postgres. Alternatively, you could set the max-pool-size and steady-pool-size to the...
