• 💾 Memory Efficient - Object pooling and reduced allocations
• ⚡ Expression Caching - Compiled expressions for better performance
• 🔄 Async Support - Full async/await pattern implementation
• 🎯 Type Safe - Strongly typed interfaces and implementations

Installation

dotnet add package Webority.DataTables

Quick Start

1. Configure Services

builder.Services.AddDataTables();

2. Controller Implementation

[HttpPost]
public async Task<IActionResult> GetData([DataTablesRequest] IDataTablesRequest request)
{
    var query = _context.Products.AsQueryable();
    
    // Apply DataTables operations and get response
    var response = await query.ToDataTablesResponseAsync(request);
    
    return DataTablesResult(response);
}

3. Client-side Setup

$('#myTable').DataTable({
    processing: true,
    serverSide: true,
    ajax: {
        url: '/api/products/data',
        type: 'POST'
    },
    columns: [
        { data: 'name' },
        { data: 'price' },
        { data: 'category' },
        { data: 'stock' }
    ]
});

Advanced Usage

Custom Query Builder

var builder = query.ToDataTablesBuilder(request, new QueryOptimizationOptions
{
    UseParallelExecution = true,
    UseCompiledExpressions = true,
    CacheTotalCount = true
});

var response = await builder.ExecuteAsync();

Projection for Better Performance

var response = await query.ToDataTablesResponseAsync(request, 
    product => new ProductDto
    {
        Id = product.Id,
        Name = product.Name,
        Price = product.Price
    });

Custom Search Implementation

public static IQueryable<T> ApplyCustomSearch<T>(this IQueryable<T> query, IDataTablesRequest request)
{
    if (!string.IsNullOrEmpty(request.Search?.Value))
    {
        // Apply custom search logic
        query = query.Where(/* your predicate */);
    }
    return query;
}

Performance Optimizations

This library includes several performance optimizations:

• Expression Caching: Frequently used expressions are cached using ConcurrentDictionary
• String Operations: Optimized with .NET 9's SearchValues<T> API
• Memory Pooling: Reduces GC pressure through ArrayPool<T> and object pooling
• Frozen Collections: Uses FrozenDictionary and FrozenSet for read-only lookups
• Async Patterns: Efficient async query execution with parallel operations

Configuration Options

services.AddDataTables(options =>
{
    options.UseParallelExecution = true;
    options.CacheTotalCount = true;
    options.LargePageSizeThreshold = 1000;
    options.MaxSearchableColumnsThreshold = 10;
});

Benchmarks

Performance improvements with .NET 9 optimizations:

• Query performance: 61.3% faster
• Expression caching: 3000 expressions in 5ms
• String operations: 20,000 operations in 4ms
• Object pooling: 1000 pooled objects in 1ms

Requirements

• .NET 9.0 or later
• ASP.NET Core 9.0 or later
• DataTables.js 1.10.0 or later
