# Algolia Core Workflow B — Indexing & Data Sync ## Overview Keep your Algolia index synchronized with your source database. Covers full reindex, incremental updates, partial updates, synonyms, and query rules. ## Prerequisites - Completed `algolia-install-auth` setup - Familiarity with `algolia-core-workflow-a` (search) - Source database or API with change tracking (timestamps, events) ## Instructions ### Step 1: Full Reindex with replaceAllObjects ```typescript import { algoliasearch } from 'algoliasearch'; const client = algoliasearch(process.env.ALGOLIA_APP_ID!, process.env.ALGOLIA_ADMIN_KEY!); // replaceAllObjects atomically swaps index content // Internally: creates temp index → indexes all records → moves temp to target // Search continues on old data until swap is complete — zero downtime async function fullReindex(records: Record<string, any>[]) { const { taskID } = await client.replaceAllObjects({ indexName: 'products', objects: records, batchSize: 1000, // Records per batch (default 1000) }); await client.waitForTask({ indexName: 'products', taskID }); console.log(`Full reindex complete: ${records.length} records`); } ``` ### Step 2: Incremental Updates with partialUpdateObject ```typescript // Only update changed fields — much faster than full saveObjects async function updateProductPrice(objectID: string, newPrice: number) { await client.partialUpdateObject({ indexName: 'products', objectID, attributesToUpdate: { ...
