Description
To improve the performance of the Carequality Directory clusters (DEV, STAGE, and PROD), as well as the eHealth Exchange directory clusters (VAL and PROD), Sequoia plans to deploy a new version of the Sequoia Healthcare Directory server software that enables the use of compressed returned data.
The Carequality Directory has grown to the size where a query of all organizations results in an uncompressed response size of over 64MB of XML data (and more data for a JSON response). The response size will continue to grow as more organizations are added to the Carequality Directory.
Because the data being transmitted back from the Carequality servers is currently not compressed, the directory requires significant IO processing to build and transmit the response.
While the eHealth Exchange Directory is not as large as the Carequality Directory, we can foresee how there might be performance degradation as it continues to grow and return uncompressed data.
Because of the above, Sequoia will be upgrading the Carequality and eHealth Exchange servers to compress responses when a client request contains the Accept-Encoding=gzip HTTP request header.
To leverage this capability, and to avoid the previously mentioned performance issues, your organization should ensure your directory client requests contain the Accept-Encoding=gzip HTTP request header.
Please advise us by January 21st if your organization would like to delay these changes.
