1. Production Architecture: Zero-Downtime Index Alias Swapping & Real-Time CDC Sync to Meilisearch / OpenSearch
def swap_search_index_zero_downtime(client, temp_index_uid: str, prod_index_uid: str):
"""Atomically swap freshly populated search index with production index without downtime."""
task = client.swap_indexes([{"indexes": [temp_index_uid, prod_index_uid]}])
client.wait_for_task(task.task_uid, timeout_in_ms=30000)
client.delete_index(temp_index_uid)
2. Core Architectural Guarantees
- Sub-20ms Typo-Tolerant Faceted Search: Instant prefix search, dynamic price/category facets, and synonym expansion across millions of SKUs.
- Hybrid Keyword + Vector Semantic Search: Combining exact SKU/part-number matching with dense vector embeddings for natural language queries.
- Zero-Downtime Blue/Green Reindexing: Rebuilding indexes in the background and executing atomic alias swaps.
