// TRY HARD SHIT.
// I did and I'm learning a lot.
//
// 2 days ago I had no idea what I was doing but I decided I was going to create
// a database. I figured this would be a great way to learn even more about the
// databases I use today. I will write better software because I will know how they are 
// designed and the optimizations and limitations they have to work with.
//
// After two days I have:
// - Modelled column based data model (like Cassandra) on top of a key/value store (SQLite4 does I think).
// - Created an inverted index stored in the key/value store for fast seeking at query time.
// - Parse an SQL-like query syntax into an AST (abstract syntax tree).
// - Process the AST to generate a query execution plan to compose a database operation.
// - Execute the operation and return results.
//
// I had no idea how to model a column based data model or how to use an AST. 
// I didn't even know I needed them.
// I didn't think it would work. I got stuck. I asked for help. I kept trying.
//
// After 2 days this now works:

using System;
using Dazzle.Database;
using Dazzle.Database.Query;

namespace Dazzle.Benchmark.Embedded
{
    class Program
    {
        static void Main(string[] args)
        {
            // The database is pre-loaded with 1 million rows each with 50 columns of gibberish data.
            // This means 50+ million keys have been inserted into the key/value storage backend.
            var db = new DazzleDatabase(path);
            db.Open();
            var result = db.ExecuteQuery("select * from users where userid = 'kelly900000'");
        }
    }
}

/*
OUTPUT
-------------------------------------
Rows: 1,000,000.00 Columns per row: 50 Total keys in DB: 50,000,000.00 DB Size: 2.36GB
Query: select * from users where userid = 'kelly900000'

Returned Rows: 1 Columns per row: 50
Query executed in 00:00:00.0035229

I can't believe this worked without any tuning in 3.5ms!
