Fields

start_time: DateTime<Utc>

Returns the time at which the catalog booted.

start_instant: Instant

Returns the instant at which the catalog booted.

nonce: u64

session_id: Uuid

A transient UUID associated with this process.

experimental_mode: bool

Whether the server is running in experimental mode.

safe_mode: bool

Whether the server is running in safe mode.

build_info: &'static BuildInfo

Information about this build of Materialize.

aws_external_id: Option<String>

An external ID to be supplied to all AWS AssumeRole operations.

timestamp_frequency: Duration

Default timestamp frequency for CREATE SOURCE

now: NowFn

Function that returns a wall clock now time; can safely be mocked to return 0.

disable_user_indexes: bool

Whether to prevent user indexes from being considered for use.
