Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Milvus

  • Vector dimensions are capped at 32,768
  • A collection is limited to 64 fields, 1,024 partitions and 16 shards
  • Only 1 index is allowed per field
  • Search returns at most 16,384 vectors as top-k, and nq is capped at 16,384
  • Input and output per RPC is capped at 64 MB for insert, search and query
  • VARCHAR values are limited to 65,535 characters
  • Data loaded into query nodes cannot exceed 90% of available memory
  • An instance supports at most 65,536 collections

Turbopack

  • Effectively coupled to Next.js; using it standalone is not the supported path
  • Younger than the alternatives, and ecosystem plugin support is narrower than webpack’s
  • Benchmark claims have been contested publicly, so measure on your own project rather than trusting headline numbers
  • Being Vercel-driven ties its roadmap to one company’s framework priorities
