Struct RetentionConfig 

pub struct RetentionConfig {
    pub default_ttl: Option<Duration>,
    pub per_tenant_ttl: HashMap<String, Option<Duration>>,
}

Per-tenant retention configuration. Look up a TTL via ttl_for(tenant_id); None means “keep forever” for that tenant.

The default rule (from the bead): the CP heartbeat tenant (system) defaults to 30 days. The CP emits ~69k heartbeat events/day; without retention this grows unbounded for data that has no audit value past the dashboard window. Other tenants default to no TTL — user data stays put unless the owner opts in.

Per-tenant overrides win over default_ttl; “no entry” falls back to default_ttl.

Fields

default_ttl: Option<Duration>

Default TTL when no per-tenant override exists. None = keep forever.

per_tenant_ttl: HashMap<String, Option<Duration>>

Per-tenant overrides. Some(None) would mean “explicitly no TTL”; the API uses Option<Duration> directly so an entry can record an explicit “keep forever” decision distinct from “no entry”.

Implementations

impl RetentionConfig

pub fn ttl_for(&self, tenant_id: &str) -> Option<Duration>

Effective TTL for tenant_id. Returns None if the tenant has no TTL (keep forever).

Lookup order:

1. Per-tenant entry → that value (whether Some or explicit None).
2. No entry → fall back to default_ttl.

pub fn set(&mut self, tenant_id: &str, ttl: Option<Duration>)

Override the TTL for a specific tenant. Use None to mean “keep forever for this tenant”.
