event
get
Read one event by sequence number.
strata event getdb.events.get(sequence: 'int', *, as_of: 'Optional[int]' = None, as_of_time: 'Optional[TimeLike]' = None) -> 'Any'wire event_get
Reads one event from the selected branch and space by sequence number. The optional timestamp reads the record visible at that commit time. The record carries its payload, append timestamp, and hash-chain facts.
Optional reads distinguish present data from missing data. When version or timestamp facts exist on the executor output, SDK mappings should preserve them.

Example
Read an event by its sequence number.
strata event append user.created {"id":1}strata event get 0strata event get 999
_ = db.events.append("user.created", {"id": 1})db.events.get(0).event.payloaddb.events.get(999) is None
Parameters
| Name | Type | Required | Description |
|---|---|---|---|
| sequence | integer | yes | Event sequence. |
| as_of | integer or null | no | Read as of a position on the logical commit timeline - the `timestamp` from `history` output, not the `version`, and never a calendar date. To read as of a real time, use `as_of_time` instead. |
| as_of_time | integer or null | no | Read as of a real time: a wall-clock instant in microseconds since the Unix epoch (UTC), as reported by `committed_at` on a write ack or on any `history` row. Resolves to the commit at or before that instant, and fails rather than guessing if the instant falls outside the branch's recorded history. Mutually exclusive with `as_of`. |
| branch | string or null | no | Target branch. Defaults to the executor handle branch. |
| space | string or null | no | Target product space. Defaults to `"default"`. |
