Namespace Tracon · Assembly Tracon.Abstractions.dll
An age- and volume-based retention rule for a target.
```csharp
public sealed record RetentionPolicy : IEquatable
```
- Inheritance
- object ← RetentionPolicy
- Implements
- IEquatable<RetentionPolicy>
- Inherited Members
- object.GetType(), object.ToString(), object.Equals(object?), object.Equals(object?, object?), object.ReferenceEquals(object?, object?), object.GetHashCode()
## Remarks
If no record exists, nothing is deleted for the target (see
`TraconRetentionOptions`' configuration-based defaults — they
take effect only when the database has no record).
## Constructors
### RetentionPolicy\(\)
```csharp
public RetentionPolicy()
```
## Properties
### Archive
Whether to archive with `IArchiveSink` before deleting. If no
sink is registered, no row is deleted even if this field is
[true](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool).
```csharp
public bool Archive { get; init; }
```
#### Property Value
[bool](https://learn.microsoft.com/dotnet/api/system.boolean)
### CreatedAt
The creation time (UTC).
```csharp
public required DateTimeOffset CreatedAt { get; init; }
```
#### Property Value
[DateTimeOffset](https://learn.microsoft.com/dotnet/api/system.datetimeoffset)
### Enabled
Whether the policy is enabled.
```csharp
public bool Enabled { get; init; }
```
#### Property Value
[bool](https://learn.microsoft.com/dotnet/api/system.boolean)
### Id
The policy identifier.
```csharp
public required Guid Id { get; init; }
```
#### Property Value
[Guid](https://learn.microsoft.com/dotnet/api/system.guid)
### MaxAgeDays
Rows older than this age are candidates for deletion. If
[null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null), age-based deletion does not apply (only
`MaxRows`, if set, applies).
```csharp
public int? MaxAgeDays { get; init; }
```
#### Property Value
[int](https://learn.microsoft.com/dotnet/api/system.int32)?
### MaxRows
The maximum number of rows to keep in the target table. The oldest
rows over the limit are deleted. If [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null),
volume-based deletion does not apply (only `MaxAgeDays`,
if set, applies).
```csharp
public long? MaxRows { get; init; }
```
#### Property Value
[long](https://learn.microsoft.com/dotnet/api/system.int64)?
### Target
The target table name. See [RetentionTargets](/api/tracon.retentiontargets/).
```csharp
public required string Target { get; init; }
```
#### Property Value
[string](https://learn.microsoft.com/dotnet/api/system.string)
### TenantId
The tenant identifier. `"*"` means the default for all tenants.
```csharp
public required string TenantId { get; init; }
```
#### Property Value
[string](https://learn.microsoft.com/dotnet/api/system.string)
### UpdatedAt
The last-updated time (UTC).
```csharp
public required DateTimeOffset UpdatedAt { get; init; }
```
#### Property Value
[DateTimeOffset](https://learn.microsoft.com/dotnet/api/system.datetimeoffset)
