Pagination

Pagination allows you to control the number of results returned and navigate through large result sets efficiently.

​

Understanding Pagination

​

Key Concepts

1. Offset Pagination

   • Start position (offset_position)
   • Page size (page_size)
   • Total result count
   • Result consistency

2. Page Control

   • Default page size: 10
   • Maximum page size: 100
   • Forward navigation
   • Result windowing

​

Pagination Parameters

​

Configuration Options

1. Page Size

   • Controls results per page
   • Range: 1-100 results
   • Default: 10 results
   • Affects response time

2. Offset Position

   • Starting point for results
   • Zero-based indexing
   • Must be non-negative
   • Affects query performance

​

Common Use Cases

​

Result Navigation

1. List Views

   • Product catalogs
   • Document libraries
   • Search results
   • Media galleries

2. Infinite Scroll

   • Social media feeds
   • Content streams
   • Dynamic loading
   • Continuous browsing

3. Paginated Reports

   • Analytics dashboards
   • Result summaries
   • Export functions
   • Batch processing

​

Limitations

​

Technical Constraints

1. Size Restrictions

   • Maximum page size: 100
   • Maximum offset: 10,000
   • Total result limit
   • Response size limits

2. Performance Impact

   • Large offsets slow down queries
   • High page sizes increase latency
   • Memory usage grows with size
   • Server resource constraints

3. Functionality Restrictions

   • Not compatible with grouping
   • No backward pagination
   • No cursor-based navigation
   • Limited with real-time updates

​

Performance Considerations

1. Resource Usage

   • CPU impact of large offsets
   • Memory usage with large pages
   • Network bandwidth consumption
   • Cache effectiveness

2. Scaling Factors

   • Dataset size
   • Query complexity
   • Sort requirements
   • Filter conditions

​

Best Practices

​

Optimization Tips

1. Page Size Selection

   • Balance user experience
   • Consider device capabilities
   • Optimize for content type
   • Monitor performance impact

2. Implementation Patterns

   • Use reasonable page sizes
   • Implement scroll position tracking
   • Cache common page results
   • Handle edge cases

​

Common Patterns

1. Progressive Loading

   • Start with smaller pages
   • Load more as needed
   • Track loading state
   • Handle errors gracefully

2. User Experience

   • Show loading indicators
   • Maintain scroll position
   • Provide page controls
   • Display progress feedback

​

Error Handling

​

Common Issues

1. Invalid Parameters

   • Negative offset values
   • Page size out of range
   • Missing required fields
   • Type mismatches

2. Performance Problems

   • Timeout on large offsets
   • Memory limits exceeded
   • Response size too large
   • Server resource exhaustion

​

Resolution Steps

1. Parameter Validation

   • Check value ranges
   • Validate types
   • Handle missing values
   • Provide defaults

2. Error Recovery

   • Retry with smaller page
   • Adjust offset value
   • Handle timeouts
   • Provide feedback
