Elastic.Ingest.Elasticsearch

Production-ready bulk ingestion into Elasticsearch — batching, backpressure, retries, and index management handled for you.

Install

dotnet add package Elastic.Ingest.Elasticsearch

Quick start

1. Define a document with mapping attributes:

public class Product
{
    [Keyword]
    public string Sku { get; set; }

    [Text]
    public string Name { get; set; }

    [Keyword]
    public string Category { get; set; }
}

2. Declare a mapping context:

[ElasticsearchMappingContext]
[Index<Product>(Name = "products")]
public static partial class MyContext;

3. Create a channel, bootstrap, and write:

var options = new IngestChannelOptions<Product>(transport, MyContext.Product.Context);
using var channel = new IngestChannel<Product>(options);

await channel.BootstrapElasticsearchAsync(BootstrapMethod.Failure);

foreach (var product in products)
    channel.TryWrite(product);

await channel.WaitForDrainAsync(TimeSpan.FromSeconds(10), ctx);

From [Index<Product>] the channel infers: target an index named products, create component and index templates, use index bulk operations, and create a new index on each bootstrap.

Strategies

When you need more control, use the IngestStrategies and BootstrapStrategies factory methods:

// Data stream with 30-day retention
var strategy = IngestStrategies.DataStream<LogEntry>(context, "30d");
var options = new IngestChannelOptions<LogEntry>(transport, strategy, context);

// Data stream with ILM policy
var strategy = IngestStrategies.DataStream<LogEntry>(context,
    BootstrapStrategies.DataStreamWithIlm("logs-policy", hotMaxAge: "7d", deleteMinAge: "90d"));

// Index with ILM policy
var strategy = IngestStrategies.Index<Product>(context,
    BootstrapStrategies.IndexWithIlm("products-policy"));

Helper APIs

Beyond channel-based bulk ingest, the library provides helper APIs for common Elasticsearch operations. All helpers accept an ITransport instance and yield IAsyncEnumerable streams for progress monitoring.

  • PointInTimeSearch<T> — iterate all documents in an index using PIT with search_after pagination
  • ServerReindex — start a server-side _reindex and poll until completion
  • DeleteByQuery — start a _delete_by_query and poll until completion
  • ClientReindex<T> — read from a source index via PIT search and write to a destination IngestChannel
// Example: PIT search
var search = new PointInTimeSearch<MyDoc>(transport, new() { Index = "my-index" });
await foreach (var page in search.SearchPagesAsync())
    Console.WriteLine($"Got {page.Documents.Count} docs");

// Example: Server reindex
var reindex = new ServerReindex(transport, new() { Source = "old", Destination = "new" });
await foreach (var progress in reindex.MonitorAsync())
    Console.WriteLine($"{progress.FractionComplete:P0}");

Legacy channels

DataStreamChannel<> and IndexChannel<> still exist for backward compatibility but IngestChannel<T> with composable strategies is the recommended API for all new code.
