v0.1 Alpha Scope

DataVo v0.1 Alpha is a public engine preview. It is meant to show the architecture, performance direction, and core developer experience before the project claims production database maturity.

The supported path starts with direct embedding. Create a context, choose a storage mode, and execute SQL from your application.

using DataVo.Core;
using DataVo.Core.StorageEngine.Config;

using var db = new DataVoContext(new DataVoConfig
{
    StorageMode = StorageMode.InMemory
});

db.Execute("CREATE DATABASE AlphaDemo");
db.Execute("USE AlphaDemo");
db.Execute("CREATE TABLE Events (Id INT PRIMARY KEY, Name VARCHAR(80))");
db.Execute("INSERT INTO Events (Id, Name) VALUES (1, 'created')");

The alpha also includes persisted storage modes. For durability-sensitive experiments, prefer LSM strict mode so acknowledged writes wait for WAL durability.

using var db = new DataVoContext(new DataVoConfig
{
    StorageMode = StorageMode.Lsm,
    DiskStoragePath = "./alpha_data",
    LsmStrictFsync = true
});

The SQL surface is intentionally documented as a subset. You can create tables, insert rows, update rows, delete rows, query rows, build indexes, and use vector search.

CREATE TABLE Products (
  Id INT PRIMARY KEY,
  Name VARCHAR(120),
  Price FLOAT,
  Embedding VECTOR(3)
);

INSERT INTO Products (Id, Name, Price, Embedding)
VALUES (1, 'Example', 12.5, '[1,0,0]');

SELECT Id, Name
FROM Products
WHERE Price > 10
ORDER BY Price DESC
LIMIT 10;

What makes this an alpha is the boundary around the edges. Package polish, storage-format stability, EF provider completeness, migrations, server tooling, and PostgreSQL compatibility are not finished. The documentation calls those limits out directly so early users can make a practical decision.

v0.1 Scope Summary

Feature	Status	Notes
In-process embedded deployment	Supported	The core product shape is library-first, not server-first.
Public curated manual	Supported	The manual is the public documentation boundary for v0.1.
SQL execution through DataVoContext	Supported	Core SQL commands and query forms are documented.
Entity Framework bridge	Supported	Useful for basic DbSet workflows and query previews with explicit operator limits, not a full provider.
Roslyn source generators	Supported	[DataVoQuery] supports selected compiled SELECT, INSERT, and UPDATE shapes.
NuGet launch packaging	Supported	Package metadata is complete and preview packages publish to nuget.org via CI Trusted Publishing.
Stable storage format	Planned	Alpha storage files may change before a stable release.
Production support contract	Not Supported	v0.1 is early software with expected API and behavior changes.
Full RDBMS feature set	Not Supported	No stored procedures, triggers, replication, or PostgreSQL-compatible server in v0.1.
