db.batch

Combine multiple reads and writes into a single round trip. Writes run in order; reads observe prior writes.

db.batch(...ops) → [results]

Combines several operations into a single network round trip. Writes run in the order given and later reads observe the earlier writes, so you can insert a row and read it back in one call. Because every un-batched operation is its own round trip, batching is the default whenever you touch more than one row: map a list to mutations and pass them all at once instead of awaiting inside a loop.

Parameters

ops

Query | Mutation

RequiredAny table operations to run together.

Batch reads

const [vendors, orders] = await db.batch(
  Vendors.filter(v => v.status === 'approved'),
  Orders.count(o => o.status === 'pending'),
);
