ThreeHourLoadBalancingDirectors

InfoGenerateCreated ByPackages

This code generates a configuration for load balancing using multiple directors in a hypothetical server environment. Specifically, it is designed to create a list of director declarations for a three-hour duration, with one director per hour. The directors are named in the format `my_dir_X` where `X` is the director number. Each director uses a random policy for load balancing among a predefined set of backends with specific weights and includes parameters for quorum and retries. The script then consolidates all individual director declarations into a single configuration string for easy deployment.

# Starting with a base blueprint for the existing director declaration
# The blueprint groups backends into a list and defines a policy for selecting a member of the list for load balancing.
# Let's modify it to define many directors along a three-hour tour

# Define the duration of the tour
var three_hour_duration = 3 * 60 * 60; # 3 hours in seconds

# Define the number of directors (assuming one per hour for the example)
var num_directors = 3;

# Initialize a list to hold the director declarations
var director_declarations = [];

for (var i = 0; i < num_directors; i++) {
    // Define the director name
    var director_name = `my_dir_${i + 1}`;
    
    // Add the director declaration to the list
    director_declarations.push(`
    director ${director_name} random {
        .quorum = 50%;
        .retries = 3;
        { .backend = F_backend1; .weight = 2; }
        { .backend = F_backend2; .weight = 1; }
        { .backend = F_backend3; .weight = 1; }
    }
    `);
}

# Combine all director declarations into a single configuration string
var director_config = director_declarations.join('\n');

# Output the final configuration
return director_config;
