Announcing the release of Spice v1.2.0! ๐Ÿš€

Spice v1.2.0 is a significant update. It upgrades DataFusion to v45 and Arrow to v54. This release brings faster query performance, support for parameterized queries in SQL and HTTP APIs, and the ability to accelerate views. Several bugs have been fixed and dependencies updated for better stability and speed.

DataFusion v45 Highlightsโ€‹

Spice.ai is built on the DataFusion query engine. The v45 release brings:

  • Faster Performance ๐Ÿš€: DataFusion is now the fastest single-node engine for Apache Parquet files in the clickbench benchmark. Performance improved by over 33% from v33 to v45. Arrow StringView is now on by default, making string and binary data queries much faster, especially with Parquet files.

  • Better Quality ๐Ÿ“‹: DataFusion now runs over 5 million SQL tests per push using the SQLite sqllogictest suite. There are new checks for logical plan correctness and more thorough pre-release testing.

  • New SQL Functions โœจ: Added show functions, to_local_time, regexp_count, map_extract, array_distance, array_any_value, greatest, least, and arrays_overlap.

See the DataFusion 45.0.0 release notes for details.

Spice.ai upgrades to the latest minus one DataFusion release to ensure adequate testing and stability. The next upgrade to DataFusion v46 is planned for Spice v1.3.0 in May.

What's New in v1.2.0โ€‹

  • Parameterized Queries: Parameterized queries are now supported with the Flight SQL API and HTTP API. Positional and named arguments via $1 and :param syntax are supported, respectively. Logical plans for SQL statements are cached for faster repeated queries.

    Example Cookbook recipes:

    See the API Documentation for additional details.

  • Accelerated Views: Views, not just datasets, can now be accelerated. This provides much better performance for views that perform heavy computation.

    Example spicepod.yaml:

    views:
    - name: accelerated_view
    acceleration:
    enabled: true
    engine: duckdb
    primary_key: id
    refresh_check_interval: 1h
    sql: |
    select * from dataset_a
    union all
    select * from dataset_b

    See the Data Acceleration documentation.

  • Memory Usage Metrics & Configuration: Runtime now tracks memory usage as a metric, and a new runtime memory_limit parameter is available. The memory limit parameter applies specifically to the runtime and should be used in addition to existing memory usage configuration, such as duckdb_memory_limit. Memory usage for queries beyond the memory limit will spill to disk.

    See the Memory Reference for details.

  • New Worker Component: Workers are new configurable compute units in the Spice runtime. They help manage compute across models and tools, handle errors, and balance load. Workers are configured in the workers section of spicepod.yaml.

    Example spicepod.yaml:

    workers:
    - name: round-robin
    description: |
    Distributes requests between 'foo' and 'bar' models in a round-robin fashion.
    models:
    - from: foo
    - from: bar
    - name: fallback
    description: |
    Tries 'bar' first, then 'foo', then 'baz' if earlier models fail.
    models:
    - from: foo
    order: 2
    - from: bar
    order: 1
    - from: baz
    order: 3

    See the Workers Documentation for details.

  • Databricks Model Provider: Databricks models can now be used with from: databricks:model_name.

    Example spicepod.yaml:

    models:
    - from: databricks:llama-3_2_1_1b_instruct
    name: llama-instruct
    params:
    databricks_endpoint: dbc-46470731-42e5.cloud.databricks.com
    databricks_token: ${ secrets:SPICE_DATABRICKS_TOKEN }

See the Databricks model documentation.

  • spice chat CLI Improvements: The spice chat command now supports an optional --temperature parameter. A one-shot chat can also be sent with spice chat <message>.

  • More Type Support: Added support for Postgres JSON type and DuckDB Dictionary type.

  • Other Improvements:

    • New image tags let you pick memory allocators for different use-cases: jemalloc, sysalloc, and mimalloc.
    • Better error handling and logging for chat and model operations.

Full Changelog: v1.1.2...v1.2.0

Spice v1.1.2 (Apr 14, 2025)

ยท 3 min read
Phillip LeBlanc
Co-Founder and CTO of Spice AI

Announcing the release of Spice v1.1.2! ๐Ÿ”—

Spice v1.1.2 improves Delta Lake Data Connector performance, introduces new Accept headers for the /v1/sql and /v1/nsql endpoints to include query metadata with results, and resolves an issue with the Snowflake Data Connector when handling wide tables (>600 columns).

The official Tableau Connector for Spice.ai v0.1 has been released, making it easy to connect to both self-hosted Spice.ai and Spice Cloud instances using Tableau.

What's New in v1.1.2โ€‹

Query Spice.ai using Tableau

  • Delta Lake Data Connector: Upgraded delta_kernel to v0.9, and optimized scan operations, reducing query execution time by up to 20% on large datasets.

  • Snowflake Data Connector: Fixed a bug that caused failures when loading tables with more than 600 columns.

  • Query Metadata (SQL and NSQL): Added support for the application/vnd.spiceai.sql.v1+json Accept header on the /v1/sql endpoint, and the application/vnd.spiceai.nsql.v1+json Accept header on the /v1/nsql endpoint, enabling responses to include metadata such as the executed SQL query and schema alongside results.

Example:

curl -XPOST "http://localhost:8090/v1/nsql" \
-H "Content-Type: application/json" \
-H "Accept: application/vnd.spiceai.nsql.v1+json" \
-d '{
"query": "Whatโ€™s the highest tip any passenger gave?"
}' | jq

Example response:

{
"row_count": 1,

Spice v1.1.1 (Apr 7, 2025)

ยท 5 min read
Phillip LeBlanc
Co-Founder and CTO of Spice AI

Announcing the release of Spice v1.1.1! ๐Ÿ“Š

Spice v1.1.1 introduces several key updates, including a new Component Metrics System, improved Delta Data Connector performance, improved MCP tool descriptions, and expanded runtime results caching options. This release also adds detailed MySQL connection pool metrics for better observability. Component Metrics are Prometheus-compatible and accessible via the metrics endpoint.

Highlights v1.1.1โ€‹

  • Component Metrics System: A new system for monitoring components, starting with MySQL connection pool metrics. These metrics provide insights into MySQL connection performance and can be selectively enabled in the dataset configuration. Metrics are exposed in Prometheus format via the metrics endpoint.

For more details, see the Component Metrics documentation.

  • Results Caching Enhancements: Added a cache_key_type option for runtime results caching. Options include:
    • plan (Default): Uses the query's logical plan as the cache key. Matches semantically equivalent queries but requires query parsing.
    • sql: Uses the raw SQL string as the cache key. Provides faster lookups but requires exact string matches. Use sql for predictable queries without dynamic functions like NOW().

Example spicepod.yaml configuration:

runtime:
results_cache:
enabled: true
cache_max_size: 128MiB
cache_key_type: sql # Use SQL for the results cache key
item_ttl: 1s

For more details, see the runtime configuration documentation.

  • Delta Data Connector: Improved scan performance for faster query performance.

  • MCP Tools: Improved descriptions for built-in MCP tools to improve usability.

  • MySQL Component Metrics: Added detailed metrics for monitoring MySQL connections, such as connection count and pool activity.

Example spicepod.yaml configuration:

datasets:
- from: mysql:my_table
name: my_dataset
metrics:
- name: connection_count
enabled: true
- name: connections_in_pool
enabled: true
- name: active_wait_requests
enabled: true
params:
mysql_host: localhost
mysql_tcp_port: 3306
mysql_user: root
mysql_pass: ${secrets:MYSQL_PASS}

For more details, see the MySQL Data Connector documentation.

  • spice.js SDK: The spice.js SDK has been updated to v2.0.1 and includes several important security updates.

Spice v1.1.0 (Mar 31, 2025)

ยท 15 min read
Luke Kim
Founder and CEO of Spice AI

Model-Context-Protocol (MCP) support in Spice.ai Open Source

Announcing the release of Spice v1.1.0! ๐Ÿค–

Spice v1.1.0 introduces full support for the Model-Context-Protocol (MCP), expanding how models and tools connect. Spice can now act as both an MCP Server, with the new /v1/mcp/sse API, and an MCP Client, supporting stdio and SSE-based servers. This release also introduces a new Web Search tool with Perplexity model support, advanced evaluation workflows with custom eval scorers, including LLM-as-a-judge, and adds an IMAP Data Connector for federated SQL queries across email servers. Alongside these features, v1.1.0 includes automatic NSQL query retries, expanded task tracing, request drains for HTTP server shutdowns, delivering improved reliability, flexibility, and observability.

Highlights in v1.1.0โ€‹

  • Spice as an MCP Server and Client: Spice now supports the Model Context Protocol (MCP), for expanded tool discovery and connectivity. Spice can:

    1. Run stdio-based MCP servers internally.
    2. Connect to external MCP servers over SSE protocol (Streamable HTTP is coming soon!)

    For more details, see the MCP documentation.

    Usageโ€‹

    tools:
    - name: google_maps
    from: mcp:npx
    params:
    mcp_args: -y @modelcontextprotocol/server-google-maps

    Spice as an MCP Serverโ€‹

    Tools in Spice can be accessed via MCP. For example, connecting from an IDE like Cursor or Windsurf to Spice. Set the MCP Server URL to http://localhost:8090/v1/mcp/sse.

  • Perplexity Model Support: Spice now supports Perplexity-hosted models, enabling advanced web search and retrieval capabilities. Example configuration:

    models:
    - name: webs
    from: perplexity:sonar
    params:
    perplexity_auth_token: ${ secrets:SPICE_PERPLEXITY_AUTH_TOKEN }
    perplexity_search_domain_filter:
    - docs.spiceai.org
    - huggingface.co

    For more details, see the Perplexity documentation.

  • Web Search Tool: The new Web Search Tool enables Spice models to search the web for information using search engines like Perplexity. Example configuration:

    tools:
    - name: the_internet
    from: websearch
    description: 'Search the web for information.'
    params:
    engine: perplexity
    perplexity_auth_token: ${ secrets:SPICE_PERPLEXITY_AUTH_TOKEN }

    For more details, see the Web Search Tool documentation.

  • Eval Scorers: Eval scorers assess model performance on evaluation cases. Spice includes built-in scorers:

    • match: Exact match.
    • json_match: JSON equivalence.
    • includes: Checks if actual output includes expected output.
    • fuzzy_match: Normalized subset matching.
    • levenshtein: Levenshtein distance.

    Custom scorers can use embedding models or LLMs as judges. Example:

    evals:
    - name: australia
    dataset: cricket_questions
    scorers:
    - hf_minilm
    - judge
    - match
    embeddings:
    - name: hf_minilm
    from: huggingface:huggingface.co/sentence-transformers/all-MiniLM-L6-v2
    models:
    - name: judge
    from: openai:gpt-4o
    params:
    openai_api_key: ${ secrets:OPENAI_API_KEY }
    system_prompt: |
    Compare these stories and score their similarity (0.0 to 1.0).
    Story A: {{ .actual }}
    Story B: {{ .ideal }}

    For more details, see the Eval Scorers documentation.

  • IMAP Data Connector: Query emails stored in IMAP servers using federated SQL. Example:

    datasets:
    - from: imap:myawesomeemail@gmail.com
    name: emails
    params:
    imap_access_token: ${secrets:IMAP_ACCESS_TOKEN}

    For more details, see the IMAP Data Connector documentation.

  • Automatic NSQL Query Retries: Failed NSQL queries are now automatically retried, improving reliability for federated queries. For more details, see the NSQL documentation.

  • Enhanced Task Tracing: Task history now includes chat completion IDs, and runtime readiness is traced for better observability. Use the runtime.task_history table to query task details. See the Task History documentation.

  • Vector Search with Keyword Filtering: The vector search API now includes an optional list of keywords as a parameter, to pre-filter SQL results before performing a vector search. When vector searching via a chat completion, models will automatically generate keywords relevant to the search. See the Vector Search API documentation.

  • Improved Refresh Behavior on Startup: Spice won't automatically refresh an accelerated dataset on startup if it doesn't need to. See the Refresh on Startup documentation.

  • Graceful Shutdown for HTTP Server: The HTTP server now drains requests for graceful shutdowns, ensuring smoother runtime termination.

Spice v1.0.7 (Mar 26, 2025)

ยท 3 min read
Phillip LeBlanc
Co-Founder and CTO of Spice AI

Announcing the release of Spice v1.0.7 ๐ŸŽ๏ธ

Spice v1.0.7 improves memory usage when using DuckDB, improves schema inference performance when using object-store based data connectors, and fixes a bug in Dremio schema inference.

Highlights in v1.0.7โ€‹

  • DuckDB Memory Usage: Memory usage when using DuckDB has been significantly improved for data loads and refreshes through expanded use of zero-copy Arrow and multi-threading for data loads. When a duckdb_memory_limit is specified, disk spilling has been improved for greater-than-memory workloads. In addition, a new temp_directory runtime parameter supports storing temporary files to alternative location than the DuckDB data file for higher throughput. For example, temp_directory could be set to a different high-IOPs IO2 EBS volume that is separate from the duckdb_file_path.

    Automated end-to-end tests for the DuckDB Accelerator coverage has been significantly expanded.

    For configuration details, see the documentation for runtime parameters and the DuckDB Data Accelerator.

  • Schema Inference Performance for Object-Store Data Connectors: Schema inference performance has been improved, especially for large numbers of objects (1M+ objects) when using object-store based data connectors by making the object-listing and selection more efficient.

Performanceโ€‹

When compared to previous versions, Spice v1.0.7 loads DuckDB accelerated datasets significantly faster. When using the TPCH lineitem dataset at Scale Factor 100 (600M rows):

Without Indexesโ€‹

5x faster, 28% less memory usage.

v1.0.6 v1.0.7

VersionLoad TimePeak Memory Usage
v1.0.616m 3s32GB
v1.0.73m 149ms24.4GB

With Indexesโ€‹

2.5x faster. Higher memory usage in v1.0.7 is due to better resource utilization to achieve faster load times. Use the duckdb_memory_limit parameter to control memory usage.

VersionLoad TimePeak Memory Usage
v1.0.627m 9s50GB
v1.0.711m 30s77GB

v1.0.6 with indexes v1.0.7 with indexes

Documentationโ€‹

  • DuckDB Data Accelerator: Has been expanded with additional resource usage guidance.
  • Memory: A new section for memory considerations has been added to the Reference section.
