Batch Save

Use Record.save_all() to create multiple records in parallel.

Lexicon type: procedure

function handle()
  local records = {}
  for _, item in ipairs(input.items) do
    local r = Record(collection, item)
    records[#records + 1] = r
  end
  Record.save_all(records)

  local uris = {}
  for _, r in ipairs(records) do
    uris[#uris + 1] = r._uri
  end
  return { uris = uris }
end

How it works

1. Iterate over input.items and create a Record instance for each item.
2. Call Record.save_all() to save all records in parallel, rather than one at a time.
3. Collect the resulting AT URIs and return them.

Usage

const response = await fetch("http://127.0.0.1:3000/xrpc/xyz.statusphere.batchCreate", {
  method: "POST",
  headers: {
    "X-Client-Key": CLIENT_KEY,
    Authorization: `Bearer ${TOKEN}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    items: [
      { text: "First", createdAt: "2025-01-01T00:00:00Z" },
      { text: "Second", createdAt: "2025-01-01T00:01:00Z" },
    ],
  }),
});
const data = await response.json();

Use case

Batch saving is useful when a single user action should create multiple records (e.g. importing data, multi-step forms). save_all is significantly faster than calling r:save() in a loop because the PDS writes happen concurrently.
