CodeIgniter API pagination with cursor-based navigation

Real business problem: Offset-based pagination becomes slow and unreliable as datasets grow. Clients experience duplicated or missing records when data changes between requests, and your database workload spikes due to expensive OFFSET scans. This leads to poor user experiences, higher infrastructure costs, and increased support tickets.

DevionixLabs implements cursor-based pagination for your CodeIgniter APIs to provide stable, efficient navigation through large result sets. Cursor pagination uses a deterministic sort key (e.g., created_at + id) and returns a cursor token that clients pass back to fetch the next page. This avoids OFFSET performance issues and ensures consistent ordering even while new records are inserted.

What we deliver:
• Cursor pagination design aligned to your existing filtering and sorting rules
• Controller/query implementation using stable sort keys and cursor token parsing
• Response format updates including next_cursor (and optional prev_cursor)
• Validation and security for cursor tokens to prevent tampering and injection
• Performance optimization for indexed queries and predictable query plans
• Testing for edge cases: empty pages, last page behavior, and concurrent writes

DevionixLabs also ensures cursor behavior works with your current API contract. We define how cursors are generated, how they expire (if needed), and how they behave with filters so clients can paginate across consistent subsets of data.

AFTER DEVIONIXLABS, your clients get faster page loads and consistent results without duplicates or gaps. Your backend reduces costly scans, improving latency and throughput. The outcome is a more scalable API that supports growth while keeping integration predictable for partners and internal consumers.
