ETS-backed registry for multi-tenant Plaid configurations.
Stores per-tenant PlaidEx.Config structs for runtime lookup.
Supports secret rotation without application restart.
Usage
# Register a tenant at runtime (e.g., when a user connects Plaid)
PlaidEx.Config.TenantRegistry.register("acme_corp",
PlaidEx.Config.new!(
client_id: vault.get("acme/plaid/client_id"),
secret: vault.get("acme/plaid/secret"),
environment: :production,
tenant_id: "acme_corp"
)
)
# Retrieve tenant config for an API call
{:ok, config} = PlaidEx.Config.TenantRegistry.get("acme_corp")
# Rotate a secret without full re-registration
PlaidEx.Config.TenantRegistry.update_secret("acme_corp", new_secret)
# Remove a tenant (e.g., when they unsubscribe)
PlaidEx.Config.TenantRegistry.deregister("acme_corp")Summary
