Reference documentation and code samples for the Firestore Admin v1 API class Field.Types.TtlConfig.
The TTL (time-to-live) configuration for documents that have this Field
set.
Storing a timestamp value into a TTL-enabled field will be treated as
the document's absolute expiration time. Timestamp values in the past
indicate that the document is eligible for immediate expiration. Using any
other data type or leaving the field absent will disable expiration for the
individual document.
