Shardis.Query.EFCore

Entity Framework Core query executor for the Shardis fluent query MVP (Where/Select, unordered streaming).

Features

  • Server-side translation of Where and final Select.
  • Unordered streaming merge across shards (arrival order, non-deterministic).
  • Automatic AsNoTracking() for all queries.
  • Optional per-shard command timeout.
  • Metrics via IQueryMetricsObserver (shard start/stop, items, completion, cancellation).

Usage

using Shardis.Query.Execution.EFCore;
using Shardis.Query;
using Microsoft.EntityFrameworkCore;

var exec = new EfCoreShardQueryExecutor(
  shardCount: 4,
  contextFactory: shardId => CreateDbContext(shardId),
  merge: (streams, ct) => Shardis.Query.Internals.UnorderedMerge.Merge(streams, ct),
  commandTimeoutSeconds: 15 // optional
);

var query = ShardQuery.For<Person>(exec)
                      .Where(p => p.Age >= 30)
                      .Select(p => new { p.Name, p.Age });

await foreach (var row in query)
{
    Console.WriteLine(row.Name);
}

Timeout: specify commandTimeoutSeconds in the executor constructor; unsupported providers silently ignore it.

Global ordering: wrap shard streams with the ordered merge helper instead of unordered merge (future API exposure).

Notes

  • Ordering across shards is not implemented in this executor; use ordered streaming merge utilities for global ordering.
  • Cancellation is cooperative; enumeration stops without throwing unless provider surfaces OperationCanceledException.
  • Ensure your DbContext factory is thread-safe and produces isolated contexts per shard query.
