BabyKusto

BabyKusto is a self-contained execution engine for the Kusto Query Language (KQL).

How to use

  1. Evaluate a simple query:

    var query = "print hello='world'";
    
    var engine = new BabyKustoEngine();
    var result = engine.Evaluate(query);
    
  2. Inject custom tabular sources:

    Implement an ITableSource, then register it with the engine using BabyKustoEngine.AddGlobalTable(ITableSource table). You can think of ITableSource as similar to an IEnumerable<T>, which allows the engine to get metadata about the table (e.g. its name and type) as well as to iterate over its data.

    Just like IEnumerable<T>, the data doesn't have to be materialized ahead of time, and your implementation of ITableSource can produce data on the fly. The type, however, has to be static and known ahead of time.

    ITableSource myTable = /*...*/; // Get your data from anywhere
    var engine = new BabyKustoEngine();
    engine.AddGlobalTable(myTable);
    
    var result = engine.Evaluate("MyTable | count");
    
  3. Play with the samples

    This repo ships with three ready-to-run samples that showcase BabyKusto in action.

    • Sample.HelloWorld: as simple as it gets, shows how to run a simple query.

    • Sample.ProcessesCli: a command-line tool that lets you explore processes running on your machine using KQL. For example, find the process using the most memory with a query like this:

      Processes
      | project name, memMB=workingSet/1024/1024
      | order by memMB desc
      | take 1
      
    • Sample.ProcessesServer: an ASP .NET Core-based web server that implements the Kusto REST API and exposes the same table Processes as the Sample.ProcessesCli sample. You can connect to the local Kusto cluster using the official Kusto client (Azure Data Explorer).

How it works

BabyKusto leverages the official Microsoft.Azure.Kusto.Language package for parsing and semantic analysis of KQL queries.

The syntax tree is then translated to BabyKusto's internal representation (see InternalRepresentation), which is evaluated by BabyKustoEvaluator.cs.

You can explore the internal representation of a query by setting dumpIRTree: true when calling BabyKustoEngine.Evaluate.
