What is the main concern when pushing a large number of metadata components to a Scratch Org?

The main concern when pushing a large number of metadata components to a Scratch Org is the possibility of exceeding limits on metadata types. Scratch Orgs, being temporary and designed for development and testing, have certain limits regarding the number and types of metadata components that can be pushed simultaneously. Each type of metadata component, such as Apex classes, Visualforce pages, or Custom Objects, has its own specific limits, and if these are exceeded, it can result in deployment failures or errors indicating that the threshold has been surpassed.

Understanding these limits is crucial for developers to ensure smooth deployments without hindrances. Planning the deployment in manageable batches can help in avoiding this issue. This consideration directly relates to the performance and functionality of the Scratch Org, which is intended for fast development cycles. Hence, monitoring and respecting the metadata limits is vital for an effective development workflow within Salesforce environments.
