The short version

  • Each has a real cost: Milvus vector dimensions are capped at 32,768; Python no built-in GUI module in standard library; requires third-party libraries for desktop applications
  • They diverge on capability: Milvus covers Billion-scale vectors, Python covers High-level syntax.

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

Python

  • No built-in GUI module in standard library; requires third-party libraries for desktop applications
  • Global Interpreter Lock (GIL) limits true multithreading for CPU-bound operations
