Shardis.Query

Primitives and abstractions for cross-shard query execution in Shardis: streaming enumerators, LINQ helpers, and executor interfaces.

NuGet Downloads License

Install

dotnet add package Shardis.Query --version 0.1.*

When to use

  • You need streaming cross-shard queries with low memory overhead.
  • You want a pluggable executor model across stores (in-memory, EF Core, Marten, …).
  • You need merge modes (unordered/ordered) that work with IAsyncEnumerable<T>.

What’s included

  • IShardQueryExecutor<TSession> — executor interface for shard-local queries.
  • Streaming enumerators & merge operators for unordered / ordered streaming.
  • LINQ adapter helpers to build shard-friendly query expressions.

Quick start

// resolve a shard query executor and run a query
var exec = provider.GetRequiredService<IShardQueryExecutor<MySession>>();
await foreach (var item in exec.QueryAsync(sessionFactory, myQuery, CancellationToken.None))
{
    // process streamed items
}

Configuration / Options

  • Merge modes: unordered (fastest) and ordered (global key selector).
  • Backpressure/channel capacity is configurable on the broadcaster/merge layer.

Integration notes

  • Pair with a concrete provider package (e.g., Shardis.Query.Marten, EF Core sample).
  • Requires a shard session factory and a query object understood by the provider.

Capabilities & limits

  • ✅ Streaming across shards with O(shards + channel capacity) memory
  • ✅ Pluggable store providers
  • ⚠️ Ordered streaming requires a stable key selector and may add latency
  • 🧩 TFM: net8.0, net9.0; Shardis ≥ 0.1
