Cloudflare published The source texts -intended edition proxy server pgbouncer used to maintain a pool of open compounds to DBMS PostgreSQL. PGBOUNCER allows you to establish applications to postgreSQL through already installed connections to exclude the constant execution of resource -intensive repeated opening and closing joints and reduce the number of active compounds to postgreSQL.
The changes proposed in the fork are aimed at a more stringent isolation of resources at the level of individual databases (load on CPU, memory consumption and input/output intensity) and ensuring limiting the number of compounds in linking to the user and the compounds of the compounds. For example, a published force has implemented the ability to limit the size of the compound pool for each user, correctly working in configurations with authentication named Host (HBA, Host-Based Authentication). In addition, support for dynamic changes in restrictions on the number of compounds from each user has been added, which allows us to more flexibly cut users who send many resource -intensive requests.
