Orb's backfill feature allows you to amend or replace events in a given time frame. This can be useful in cases where revising events is necessary, such as in the case of incorrect event reporting.

Backfills now support filtering across time ranges and with computed properties, which enables the expressiveness of SQL when replacing events. Using the `deprecation_filter` field requires `replace_existing_events` to be true and the filter must be an expression that is coercible to a boolean - for more information, see the docs here.
