In a Qlik Sense environment with two nodes, what should the admin change in the max_connections in the postgresql.conf file to add four new nodes?

To determine the correct value for max_connections in the postgresql.conf file when adding four new nodes to a Qlik Sense environment that currently has two nodes, it's crucial to understand how connection limits are calculated within this context.

The max_connections setting in the PostgreSQL configuration file specifies the maximum number of concurrent connections to the database server. In a Qlik Sense clustered environment, each node typically requires its own set of connections to handle user requests and operations.

Initially, with two nodes, if the environment was set efficiently, the max_connections might have been set to a value that supports the necessary workload effectively. When adding four new nodes to the cluster, the total number of nodes becomes six. Therefore, to properly accommodate an increase in nodes and prevent connection issues, the max_connections setting should ideally be adjusted to reflect this increase.

In practice, it is a good rule of thumb to allocate enough connections to cover the expected load—often calculated with a typical multiplier based on the number of nodes. The recommended value for max_connections in this scenario would be to increase the limit significantly enough to ensure server stability and support high concurrency.

With six nodes, a common estimate may set max_connections at 600. This allows for each node to comfortably handle multiple connections simultaneously without
