rowKey

rowKey(row, pkColumns): string

Defined in: packages/client/src/worker/live-diff.ts:20

The stable key for a result row (§4). With pkColumns, join their values (composite-safe) — this is the diff-keying identity, so a row whose PK is unchanged is the SAME logical row even if other columns moved. Without pkColumns (a keyless query) fall back to the whole-row JSON value: still diff-shaped (never a full resend), but an update surfaces as remove+add rather than a changed — the documented keyless fallback. Duplicate identical keyless rows collapse under this scheme (accepted for the fallback).

Parameters

row

Record<string, unknown>

pkColumns

readonly string[] | undefined

Returns

string
