Module resty.cassandra.policies.reconnection.exp

Exponential reconnection policy.

This policy will allow the cluster module to retry an unhealthy node after an exponentially growing delay.

Info:

• Author: thibaultcha

Functions

new (base_delay, max_delay)

Create an exponential reconnection policy.

Functions

new (base_delay, max_delay)

Create an exponential reconnection policy. Instanciates an exponential reconnection policy for resty.cassandra.cluster

Parameters:

• base_delay number The original, minimum delay for the first reconnection attempt. Futher attempts will grow exponentially from this delay.
• max_delay number The maximum allowed delay for a reconnection attempt.

Returns:

table policy: An exponential reconnection policy.

Usage:

local Cluster = require "resty.cassandra.cluster"
local exp_reconn = require "resty.cassandra.policies.reconnection.exp"

local policy = exp_reconn.new(1000, 60000)
local cluster = assert(Cluster.new {
  reconn_policy = policy
})
