Mar 1, 2025March 2025 focused on stabilizing array-related queries and improving memory efficiency for large result sets in surrealdb/surrealdb. Delivered a critical bug fix for Array SELECT START/LIMIT slicing with correct element handling and permission checks, and implemented a streaming-based key retrieval path to avoid materializing all keys in memory. Added comprehensive tests for START/LIMIT edge cases to prevent regressions. These changes enhance correctness, reliability, and scalability of large queries, delivering tangible business value through faster, more memory-efficient data access.
