Insurance Eligibility

Summary

This enhancement to Insurance Eligibility introduces configurable settings to manage the aggressiveness of the eligibility service query and prevent the queue from backing up.

Background

Previously, errors in the eligibility query were causing backups in the queue due to overly aggressive default query settings.

Feature Description

With this change, polling speed settings for the eligibility service query may now be controlled via new configuration settings.

Two new application settings EligibilityServiceMaxThread and EligibilityServiceIdleSleep have been introduced to assist in regulating the number of threads and the polling speed for the service.

Additionally, Max Pool Size is a new configuration setting to manage the number of connections used for eligibility threads.

Although the default the setting values for EligibilityServiceMaxThread and EligibilityServiceIdleSleep are equal to the values used previously, those values are not recommended as they may cause database stress.

Based on performance testing, the following settings are recommended:

EligibilityServiceIdleSleep = 250

EligibilityServiceMaxThreads = 100

Max Pool Size=1000;

o    Although RIS would never use 1000 connections as each of the eligibility threads only opens one connection, a setting greater than the EligibilityServiceMaxThreads value is needed is because startup and backend processes need database connections.
