- ✓Parallel index building and maintenance for large-scale deployments
- ✓Expression indexing and partial indexing for optimization flexibility
Cons
- ✗Performance limitations at billion-vector scales compared to specialized databases
- ✗Requires PostgreSQL memory tuning (shared_buffers, maintenance_work_mem) for optimal performance
- ✗Limited to PostgreSQL's built-in distance functions without extensibility for custom metrics
- ✗Heavy vector query loads can impact concurrent regular PostgreSQL operations
- ✗No native multi-node sharding capabilities, requiring manual partitioning strategies
- ✗Index maintenance operations can be slower than purpose-built vector databases
- ✗Memory consumption increases significantly with HNSW indexes for high-dimensional vectors
- ✗Iterative scans feature requires PostgreSQL 16+ for optimal filtered query performance
- ✗Limited advanced quantization techniques beyond basic binary quantization
- ✗No GPU acceleration support for specialized high-performance workloads
