Spice v1.3.0 (May 19, 2025)

May 20, 2025 · 6 min read

Co-Founder and CTO of Spice AI

Announcing the release of Spice v1.3.0! 🏎️

Spice v1.3.0 accelerates data and AI applications with significantly improved query performance, reliability, and expanded Databricks integration. New support for the Databricks SQL Statement Execution API enables direct SQL queries on Databricks SQL Warehouses, complementing Mosaic AI model serving and embeddings (introduced in v1.2.2) and existing Databricks catalog and dataset integrations. This release upgrades to DataFusion v46, optimizes results caching performance, and strengthens security with least-privilege sandboxed improvements.

What's New in v1.3.0

Databricks SQL Statement Execution API Support: Added support for the Databricks SQL Statement Execution API, enabling direct SQL queries against Databricks SQL Warehouses for optimized performance in analytics and reporting workflows.

Example spicepod.yml configuration:

datasets:
  - from: databricks:spiceai.datasets.my_awesome_table
    name: my_awesome_table
    params:
      mode: sql_warehouse
      databricks_endpoint: ${env:DATABRICKS_ENDPOINT}
      databricks_sql_warehouse_id: ${env:DATABRICKS_SQL_WAREHOUSE_ID}
      databricks_token: ${env:DATABRICKS_TOKEN}

For details, see the Databricks Data Connector documentation.

Improved Results Cache Performance & Hashing Algorithm: Spice now supports an alternative results cache hashing algorithm, ahash, in addition to siphash, being the default. Configure it via:
```
runtime:
  results_cache:
    hashing_algorithm: ahash # or siphash
```
The hashing algorithm determines how cache keys are hashed before being stored, impacting both lookup speed and protection against potential DOS attacks.

Using ahash improves performance for large queries or query plans. Combined with results cache optimizations, it reduces 99th percentile request latency and increases total requests/second for queries with large result sets (100k+ cached rows). The following charts show performance tested against the TPCH Query #17 on a scale factor 5 dataset (30+ million rows, 5GB):

Latency Req/sec

Note: ahash was not available in v1.2.2, so it is excluded from comparisons.

To learn more, refer to the Results Cache Hashing Algorithm documentation.
SQL Query Performance: Optimized the critical SQL query path, reducing overhead and improving response times for simple queries by 10-20%.
DuckDB Acceleration: Fixed a bug in the DuckDB acceleration engine causing query failures under high concurrency when querying datasets accelerated into multiple DuckDB files.
Container Security: The container image now runs as a non-root user with enhanced sandboxing and includes only essential dependencies for a slimmer, more secure image.

DataFusion v46 Highlights

Spice.ai is built on the DataFusion query engine. The v46 release brings:

Faster Performance 🚀: DataFusion 46 introduces significant performance enhancements, including a 2x faster median() function for large datasets without grouping, 10–100% speed improvements in FIRST_VALUE and LAST_VALUE window functions by avoiding sorting, and a 40x faster uuid() function. Additional optimizations, such as a 50% faster repeat() string function, accelerated chr() and to_hex() functions, improved grouping algorithms, and Parquet row group pruning with NOT LIKE filters, further boost overall query efficiency.
New range() Table Function: A new table-valued function range(start, stop, step) has been added to make it easy to generate integer sequences — similar to PostgreSQL’s generate_series() or Spark’s range(). Example: SELECT * FROM range(1, 10, 2);
UNION [ALL | DISTINCT] BY NAME Support: DataFusion now supports UNION BY NAME and UNION ALL BY NAME, which align columns by name instead of position. This matches functionality found in systems like Spark and DuckDB and simplifies combining heterogeneously ordered result sets.

Example:
```
SELECT col1, col2 FROM t1
UNION ALL BY NAME
SELECT col2, col1 FROM t2;
```

See the DataFusion 46.0.0 release notes for details.

Spice.ai adopts the latest minus one DataFusion release for quality assurance and stability. The upgrade to DataFusion v47 is planned for Spice v1.4.0 in June.

Spice v1.2.0 (Apr 28, 2025)

April 29, 2025 · 12 min read

Evgenii Khramkov

Senior Software Engineer at Spice AI

Announcing the release of Spice v1.2.0! 🚀

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 Highlights

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

Faster Performance 🚀: 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 📋: 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 ✨: 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 v1.2.0

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.
