pub const BATCH_MAX_ITEMS: usize = 1000;Expand description
Default upper bound on items in a single batch request. Server
backends enforce this before any SQL runs and surface
CoolError::Validation on the outer Result when exceeded.
The cap is identical for all five batch operations; deviating
per-op would invite footguns where batch_get accepts a list
that batch_create of the same length rejects.
