Spice Cloud & Spice.ai Enterprise 1.7.0 are now live, bringing performance upgrades with DataFusion v49, real-time full-text search indexing, EmbeddingGemma support, and improvements across search, embeddings, and API integrations. Spice Cloud customers will automatically upgrade to v1.7.0 on deployment, while Spice.ai Enterprise customers can consume the Enterprise v1.7.0 image from the Spice AWS Marketplace listing.

What's New in v1.7.0

DataFusion v49 Upgrade

Spice now runs on DataFusion v49, delivering lower latency and improved query optimization.

DataFusion v49 highlights include:

• Dynamic filters and pushdown to skip unnecessary reads in ORDER BY & LIMIT queries
• Compressed spill files to reduce disk usage during large sorts and aggregations
• Support for ordered-set aggregates with WITHIN GROUP
• New REGEXP_INSTR function to identify regex match positions

EmbeddingGemma Support

Spice now supports EmbeddingGemma, Google's latest embedding model for text and documents. It delivers high-quality embeddings for semantic search, retrieval, and recommendation tasks. Configure it directly in your Spicepod via HuggingFace.

Embedding Request Caching

Repeated embedding requests can now be cached in the Spice runtime. This reduces both latency and costs, with configurable cache size and TTL options. Check out the caching documentation for more details.

Real-Time Indexing for Full Text Search

Full-text indexing now supports real-time changes from CDC streams such as Debezium. New events are searchable as they arrive, ensuring continuously fresh results.

OpenAI Responses API Tool Calls with Streaming

The OpenAI Responses API in Spice now supports tool calls with streaming. Results from tools like web_search and code_interpreter are streamed as they're generated, enabling more responsive agent and application experiences.

Bug & Stability Fixes

v1.7.0 includes numerous fixes and improvements:

• CDC streams readiness and full-text indexing reliability
• Vector search pipeline and vector_search UDTF fixes
• Kafka schema inference, consumer group persistence, and cooperative mode
• Error reporting improvements (e.g., ThrottlingException handling)
• Iceberg connector support for LIMIT pushdown
• S3 Vector ingestion reliability and tracing fixes
