大意是开启事务后,每次操作一张表,会进行一次表级的lock操作,并增加lock的大小,当lock的大小超过了默认的限定值,就会抛出异常。 postgres中默认max_locks_per_transaction大小是64 官方对此的解释: 共享锁表跟踪在max_locks_per_transaction * (max_connections + max_prepared_transactions) 个对象(如表)上的锁。
max_connections,1000,Sets the maximum number of concurrent connections. max_files_per_process,1000,Sets the maximum number of simultaneously open files for each server process. max_function_args,100,Shows the maximum number of function arguments. ...
Clearly, havingmax_connections = 400is not going to allow a high-traffic application to handle all the work that the users give to it. Somehow, the database needs to be scaled up to meet these requirements, but doing so would seem to require some magic. One option is to se...
To enable logical replication on bare metal, VMs (EC2/GCE/etc), or Docker, configure the following parameters in the postgresql.conf file for your Postgres database:ParameterDescriptionSet value to wal_level Type of coding used within the Postgres write-ahead log logical max_wal_senders The ...
