A basic understanding of the selective query concept is fundamental to scalability on the Salesforce platform. Non-selective queries have a significant performance impact on List Views, Reports and SOQL and can often result in Apex Trigger runtime exceptions as below – as the data volume increases over time. [code language=”java”] System.QueryException Cause: null Message: Non-selective […]
This video post provides a technical overview of the Platform Cache feature added in the Winter ’16 release.
This post provides an outline approach to consider when performing an internal audit of an existing (or emerging) Salesforce implementation. As an individual who specialises in the provision of such quality assurance services from an external perspective, I’m convinced that most projects would benefit from a periodic internal review, perhaps augmented by some occasional external […]
A Salesforce instance is a constrained environment where limits exist in respect to capacity and execution. Examples of capacity limits being data storage, number of active users, number of custom objects/custom fields/picklists etc. examples of execution limits being API calls per 24-hour period, SOQL queries executed within an Apex transaction, Viewstate size in Visualforce pages […]
The concept of any-org development is an interesting one. The strict definition, to my mind, being the development of a set of components (perhaps packaged) that are designed and coded specifically to install and function in any Salesforce org. This is typically an ISV concern, where testing and maintaining a single-code base can be highly […]
Understanding how the Salesforce Query Optimiser (SQO) works is fundamental to delivering performance at the data layer. Good practice in this regard, as part of an optimised physical data model implementation, is key to delivering efficient data access at the application layer. In short, certain fields are indexed by default, custom indexes can be added […]
Experienced Salesforce technical architects will always look to declarative solution options before considering technical alternatives. This type of thinking is best practice and indicative of an architect considerate of TCO (total cost of ownership), future maintenance etc.. In my case I’ll go as far as to challenge requirements such that I can deliver a fit […]
I think it’s fair to say that consideration of reporting and analytics is not traditionally a technical architect’s direct concern. In the Salesforce context I always challenge this presumption and promote the idea that a project architect should absolutely be looking at the high-level analytical requirements during the foundation stage of the project. Why you […]
As a best practice I implement a hierarchy type Custom Setting (OrgBehaviourSettings__c) which enables a highly useful, org-level selective switching-off of dynamic behaviour such as Triggers. The setting usually has independent flags for workflow rules and validation rules also, with the setting fields being referenced in rule entry criteria and formula expressions respectively. Having such […]
In reading this interesting title (via MEAP) on the trendy topic of Big Data, I was reminded of the many times I’ve had to explain the general principles of the Salesforce data storage model and specifically how many records can be stored per user. In short each user license gets an allowance, the edition of […]
