Toolkit - A Tridion File System Broker

In the following series of posts, I am describing a custom file system storage, called the Toolkit, that mimics the behaviour of the Tridion File System Broker. There are a couple of noticeable differences from the File System Broker in that it:

The Toolkit offers the following functionality:

Backing the Toolkit implementation are the following:
  • Model Factory offering CRUD operations on models backed by a cache for model objects and a file system provider acting as data layer abstraction;
  • File System Provider acting as Data Abstraction Layer that offers CRUD operations between model objects, JSON de-/serializer, JSON files, and the underlying file system;
  • Cache Factory offering EHCache memory storage for frequently used models;
  • Cache invalidation mechanism that removes stale items from cache;
  • Custom indexes and handling logic that provides performance for content queries;
  • Tridion Deployer module and Tridion Storage extension that publish/unpublish the JSON files from the file system;

Each of the modules above are described in following posts.

The Toolkit is written in plain Java without using any additional framework or third party data access / indexing API. The Toolkit does use FasterXML's Jackson JSON API in its interaction with JSON.

Toolkit is available as open source on the GitHub project of this blog (https://github.com/mitza13/yet-another-tridion-blog/tree/master/File System Toolkit). The distributable JARs are available in its /distributable folder.

Some performance metrics of the Toolkit can be found in post Toolkit - Performance.

Installation and configuration steps can be found in post Toolkit - Installation and Configuration.

Examples for using the Toolkit API can be found in post Toolkit - Examples.

Running sp_updatestats on AWS RDS database

Part of the maintenance tasks that I perform on a MSSQL Content Manager database is to run stored procedure sp_updatestats . exec sp_updatestats However, that is not supported on an AWS RDS instance. The error message below indicates that only the sa  account can perform this: Msg 15247 , Level 16 , State 1 , Procedure sp_updatestats, Line 15 [Batch Start Line 0 ] User does not have permission to perform this action. Instead there are several posts that suggest using UPDATE STATISTICS instead: https://dba.stackexchange.com/questions/145982/sp-updatestats-vs-update-statistics I stumbled upon the following post from 2008 (!!!), https://social.msdn.microsoft.com/Forums/sqlserver/en-US/186e3db0-fe37-4c31-b017-8e7c24d19697/spupdatestats-fails-to-run-with-permission-error-under-dbopriveleged-user , which describes a way to wrap the call to sp_updatestats and execute it under a different user: create procedure dbo.sp_updstats with execute as 'dbo' as

Content Delivery Monitoring in AWS with CloudWatch

This post describes a way of monitoring a Tridion 9 combined Deployer by sending the health checks into a custom metric in CloudWatch in AWS. The same approach can also be used for other Content Delivery services. Once the metric is available in CloudWatch, we can create alarms in case the service errors out or becomes unresponsive. The overall architecture is as follows: Content Delivery service sends heartbeat (or exposes HTTP endpoint) for monitoring Monitoring Agent checks heartbeat (or HTTP health check) regularly and stores health state AWS lambda function: runs regularly reads the health state from Monitoring Agent pushes custom metrics into CloudWatch I am running the Deployer ( installation docs ) and Monitoring Agent ( installation docs ) on a t2.medium EC2 instance running CentOS on which I also installed the Systems Manager Agent (SSM Agent) ( installation docs ). In my case I have a combined Deployer that I want to monitor. This consists of an Endpoint and a

SDL Web 8 - Content Delivery Microservices

Among the new features in SDL Web 8 there are the Content Delivery Microservices, namely: Audience Manager Content Deployer Contextual Image Delivery Discovery Service Dynamic Content Dynamic Linking Profiling and Personalization Metadata Query Taxonomy User Generated Content These microservices make up the Content Interaction Services and they expose the existing Content Delivery in-process APIs as RESTful services. They provide the server-side component in a Services-Oriented Architecture and act as data layer between the the web client and the Content Delivery Storage Layer. According to the SDL marketing, these microservices: Simplify upgrades, thus offering shorter time to value Modernize architecture, offering better separation between the web application and Tridion APIs Offer more flexibility with less downtime and improved scalability Improve quality, being self-running, contained and having less dependencies In technical words, these microservices
