`STRICT_MODE` if `true`, exceptions are thrown and logged with `ERROR` level whenever loader encounters problems with input file, such as invalid format, repeated keys, missing fields, mismatches and other potential errors.
`UPDATE_INTERVAL_SEC` the interval in which a new snapshot is created, either by reloading the entire graph or if the format supports delta-updates, out of the cached changes.
`UPDATE_THRESHOLD` (only relevant if the format supports delta updates) the maximum number of changes that are cached before a new snapshot is created.
