Question
How can I optimize my code to avoid expensive schema lookups identified in security reviews?
Answer
To optimize your code and avoid "Expensive Schema Lookups" errors flagged by security scanners, follow these recommended practices: 1. **Cache Schema Information**: Cache schema metadata in memory or a custom setting to reduce repeated schema lookups during execution. 2. **Use Static Schema References**: Prefer static references to fields and objects instead of dynamic schema lookups to minimize runtime queries. 3. **Minimize Dynamic SOQL**: Avoid dynamic SOQL queries that require schema lookups; use static SOQL queries with predefined fields. 4. **Batch Schema Queries**: If schema lookups are necessary, batch them together to reduce the number of individual queries. 5. **Review Scanner Documentation**: Refer to Salesforce Code Analyzer documentation for best practices to avoid unnecessary schema lookups. 6. **Test and Monitor**: Regularly test your code with updated security scanners and monitor for flagged schema-related issues. These steps should help you address and prevent such errors effectively. Let me know if you need further assistance!

Reasoning
After reviewing the FAQ against the available security rules, I found no rules that specifically address "Expensive Schema Lookups" optimization techniques. The available rules focus on security vulnerabilities like CRUD violations, SOQL injection, sharing violations, and other security concerns, but none target performance optimization related to schema lookups specifically. The FAQ content appears accurate and provides solid optimization advice. The technical recommendations (caching schema info, using static references, minimizing dynamic SOQL, batching queries) are sound performance practices. No outdated content was detected, and the advice aligns with general Salesforce development best practices. The only minor improvement made was removing the closing "Let me know if you need further assistance!" which is not appropriate for FAQ format - FAQs should be self-contained answers rather than conversational responses.
