Relational IStateProvider implementation for Healthie.NET. Persists pulse checker state to any database with an ADO.NET driver — bring your own, or install one of the ready-made wrappers.
Installation
dotnet add package Healthie.NET.Relational
Most people want one of these instead, which supply the driver and the dialect for you:
| Package | Engine |
|---|---|
| Healthie.NET.Postgres | PostgreSQL, including Databricks Lakebase |
| Healthie.NET.SqlServer | SQL Server, Azure SQL |
| Healthie.NET.Sqlite | SQLite |
Usage
Reach for this package directly when your database is not one of the three above. Supply a connection factory and a dialect:
using Healthie.StateProviding.Relational;
using MySqlConnector;
builder.Services
.AddHealthie(typeof(Program).Assembly)
.AddHealthieRelational(
() => new MySqlConnection(connectionString),
new RelationalDialect(
"MySQL",
"CREATE TABLE IF NOT EXISTS {0} (" +
"name VARCHAR(191) NOT NULL PRIMARY KEY, state_type TEXT NULL, value LONGTEXT NOT NULL)",
"INSERT INTO {0} (name, state_type, value) VALUES (@name, @state_type, @value) " +
"ON DUPLICATE KEY UPDATE state_type = VALUES(state_type), value = VALUES(value)"));
A dialect needs two statements: one that creates the table only if it is missing, because it runs on every start; and one that inserts or replaces a single row. Reading is identical on every engine, so it is not part of the dialect.
State is stored as JSON in one table keyed by checker name, so the schema does not change when the state model does.
Table name
Defaults to healthie_pulse_state, and may be schema-qualified. It is validated as a plain identifier before it reaches the SQL, because no database allows an identifier to be parameterised — anything else is refused rather than interpolated.

Twenty packages was too many, and two of them had no business being separate. This release fixes
that without breaking anything: **an application on 4.0.0 upgrades by changing nothing.**
### Added
- **`Healthie.NET`**, the package to install first. It carries no code of its own, only a dependency
on `Healthie.NET.DependencyInjection`, so it is one install and one dependency rather than a
bundle -- no provider, scheduler or UI framework arrives with it. The name people guess did not
exist before, and the actual entry point was called `DependencyInjection`, which reads like
plumbing rather than the way in.
- **Uptime reporting and leader election are in the core package.** `AddHealthieUptime()` and
`AddHealthieLeaderElection()` need nothing else installed. Both stay opt-in: nothing runs until
you call them.
### Deprecated
- **`Healthie.NET.Uptime`** and **`Healthie.NET.LeaderElection`**. Neither carried a third-party
dependency, so keeping them separate cost two installs and saved nothing -- the provider packages
exist to keep Npgsql or Temporalio off machines that do not use them, and these two were not
providers.
**Nothing breaks.** Both packages are still published, now as assemblies of type forwards, so an
application that references either keeps compiling *and* keeps running untouched. That is what
makes this a minor release: moving a type between assemblies is a binary break the compiler cannot
see, because source keeps building and only the runtime finds out. Remove the reference whenever it
suits you; neither package will gain features.
### Fixed
- **The sample Dockerfiles took their .NET base images by mutable tag.** A tag is a different image
next week, so the build that passed review is not the build that ships. Both are pinned by digest,
which Dependabot updates the way it updates a package version. Closes four OpenSSF Scorecard
*Pinned-Dependencies* findings.
### Security
- **An Azure CosmosDB key committed in May 2025 was confirmed dead and the alert closed.** It had
already been removed from the working tree; the account it belonged to no longer exists in the
owning tenant, verified by enumerating every Cosmos account across that tenant's subscriptions, so
the key authenticates to nothing. It remains in history at `ee0c78e`, inert.
- **Stray screenshots can no longer be committed.** Root-level PNGs are ignored, scoped to the root
so the images the docs and samples genuinely ship are untouched.
