Hi Aem-community,

Is it better use node iterator or querybuilder to find components on page and get properties of components?

When you need to find that on a single page, use the iterator approach; the static overhead of queries is typically higher than the cost of iterating.

It depends on couple of things: How complex is the query and how many nodes you are planning to traverse.

For a small number of nodes, iterating through JCR nodes using a node iterator is often more efficient.

For larger node sets or when dealing with more complex queries, it's generally better to set up Oak indexes and use QueryBuilder.

@keerthi0555 Node iteration is always faster and performance efficient that Query Builder. If you know the exact path to iterate and get the values , I would say use Node Iteration.

Please find a more detailed explanation from @joerghoh https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/child-node-iterating/m-p/305931/highlight/true#M28258

If you want to iterate through all the resources then go with iterator.

If you want a specific resource(s) with specific property then search using query builder.

Depends on your use case.
