Struct DbApiKeyConfig 

pub struct DbApiKeyConfig {
    pub cache_size: u64,
    pub cache_ttl_secs: u64,
    pub unknown_cache_ttl_secs: u64,
    pub unknown_cache_size: u64,
}

Cache and audit knobs for DbApiKeyAuthProvider, read from env with defaults.

Fields

cache_size: u64

MICROMEGAS_API_KEY_CACHE_SIZE, default 10_000.

cache_ttl_secs: u64

MICROMEGAS_AUTH_CACHE_TTL_SECONDS, default 60 – a single flat, unprefixed knob (no {prefix}_ role variant) shared with DbAudienceGrantsConfig/DbGroupsConfig’s own positive-cache TTL: one value governs the API-key, audience-grant, and group snapshot caches process-wide, across every role. Also the bound on revocation latency: a DELETE writes revoked_at but cannot invalidate a remote process’s cache, so a revoked key keeps authenticating until this TTL elapses.

unknown_cache_ttl_secs: u64

MICROMEGAS_API_KEY_UNKNOWN_CACHE_TTL_SECONDS, default 10. Shorter than cache_ttl_secs so a freshly minted key is not masked by an earlier probe of that same (not-yet-existing) string for longer than necessary.

unknown_cache_size: u64

MICROMEGAS_API_KEY_UNKNOWN_CACHE_SIZE, default 10_000.

Implementations

impl DbApiKeyConfig

pub fn from_env_with_prefix(prefix: &str) -> DbApiKeyConfig

Resolves each API_KEY_-specific knob as {prefix}_* first, falling back to the unprefixed name, the same {prefix}_*-with-fallback convention crate::env::resolve_prefixed_var implements for every other knob in this crate. With an empty prefix this is identical to the unprefixed vars, so an unprefixed caller just passes "".

cache_ttl_secs is the exception: it reads the flat, unprefixed MICROMEGAS_AUTH_CACHE_TTL_SECONDS knob directly (prefix is ignored for this one field), the same single process-wide value DbAudienceGrantsConfig/DbGroupsConfig read – there is exactly one value for this knob, no per-role distinction.
