ChalkQL.Sources

Standard data-source implementations for ChalkQL, the federated SQL query engine for .NET powered by Apache Calcite.

ci

Targets .NET 10.

dotnet add package ChalkQL.Sources

ChalkQL.Sources depends on ChalkQL, so a separate reference to the core package is not required.

Included source implementations:

Source
Chalk.Sources.Poco application-owned POCO collections exposed as relational tables
Chalk.Sources.Ado ADO.NET sources with capability-aware SQL pushdown
Chalk.Sources.DuckDb DuckDB integration with native data-chunk reading
Chalk.Sources.Conformance verifies a source's declared capabilities against the source itself

POCO sources

Application-owned collections can be exposed directly without copying their rows into another store.

Tables may declare keys, collations, statistics and indexes so the planner can make use of structure the application already knows about.

var source = new PocoSourceBuilder("mem")
    .AddTable("rates", rows, t => t
        .OrderedBy(r => r.Ts)
        .ThenBy(r => r.Currency)
        .UniqueKey(r => r.Ts, r => r.Currency))
    .Build();

Remote SQL sources

ADO.NET and DuckDB sources declare which relational operations they can evaluate. ChalkQL pushes supported work to the source and executes the remainder inside the .NET host.

Queries may span several sources at once, including joins between remote databases and application-owned tables.

Custom sources

Chalk.Sources.Abstractions is distributed with the core ChalkQL package. Implement ISourceRuntime when the built-in sources are not appropriate.

Things that will bite you

Not all ADO.NET providers support zero-allocation reads. Whether ChalkQL can avoid intermediate allocations depends on the provider and the data-access path it exposes.

Documentation

See the ChalkQL guide for source configuration and extension points, and the tutorial for worked federation examples.

The full project source and documentation are in the ChalkQL repository.
