We shard the data and index on about 6 x n2-standard-96 spot instances so the total cost of indexing the entire deep1b is less than $12. We are working on to make it $6. We separate indexing and query VMs. For queries we use dedicated VMs. USearch numbers look great and are better than ours if you run the query and indexing on the same VM/node. We believe design-wise distributed, task-oriented design is the right way to handle vector search for thousands of tenants with different size datasets. Data ingest is also a separate task for us so Ingest, Index and Query are all handled by different cluster of VMs.
