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.

Phillip LeBlanc
Co-Founder and CTO of Spice AI

Announcing the release of Spice v1.1.2! 🔗

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 v1.1.2​

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": "What’s the highest tip any passenger gave?"
  }' | jq

Example response:

{
  "row_count": 1,
  "schema": {
    "fields": [
      {
        "name": "highest_tip",
        "data_type": "Float64",
        "nullable": true,
        "dict_id": 0,
        "dict_is_ordered": false,
        "metadata": {}
      }
    ],
    "metadata": {}
  },
  "data": [
    {
      "highest_tip": 428.0
    }
  ],
  "sql": "SELECT MAX(\"tip_amount\") AS \"highest_tip\"\nFROM \"spice\".\"public\".\"taxi_trips\""
}

The v0.13.0-alpha release significantly improves federated query performance and efficiency with Query Push-Down. Query push-down allows SQL queries to be directly executed by underlying data sources, such as joining tables using the same data connector. Query push-down is supported for all SQL-based and Arrow Flight data connectors. Additionally, runtime metrics, including query duration, collected and accessed in the spice.runtime.metrics table. This release also includes a new FTP/SFTP data connector and improved CSV support for the S3 data connector.

Highlights​

  • Federated Query Push-Down (#1394): All SQL and Arrow Flight data connectors support federated query push-down.

  • Runtime Metrics (#1361): Runtime metric collection can be enabled using the --metrics flag and accessed by the spice.runtime.metrics table.

  • FTP & SFTP data connector (#1355) (#1399): Added support for using FTP and SFTP as data sources.

  • Improved CSV support (#1411) (#1414): S3/FTP/SFTP data connectors support CSV files with expanded CSV options.

Spice v0.12.1-alpha (May 6, 2024)

· 4 min read
Phillip LeBlanc
Phillip LeBlanc
Co-Founder and CTO of Spice AI

The v0.12.1-alpha release introduces a new Snowflake data connector, support for UUID and TimestampTZ types in the PostgreSQL connector, and improved error messages across all data connectors. The Clickhouse data connector enables data streaming by default. The public SQL interface now restricts DML and DDL queries. Additionally, accelerated tables now fully support NULL values, and issues with schema conversion in these tables have been resolved.

Highlights​

  • Snowflake Data Connector: Initial support for Snowflake as a data source.

  • Clickhouse Data Streaming: Enables data streaming by default, eliminating in-memory result collection.

  • Read-only SQL Interface: Disables DML (INSERT/UPDATE/DELETE) and DDL (CREATE/ALTER TABLE) queries for improved data source security.

  • Error Message Improvements: Improved the error messages for commonly encountered issues with data connectors.

  • Accelerated Tables: Supports NULL values across all data types and fixes schema conversion errors for consistent type handling.

AWS Secrets Manager Secret Store: Use AWS Secrets Managers as a secret store.

Custom Refresh SQL: Specify a custom SQL query for dataset refresh using refresh_sql.

Dataset Refresh API: Trigger a dataset refresh using the new CLI command spice refresh or via API.

Expanded SSL support for Postgres: SSL mode now supports disable, require, prefer, verify-ca, verify-full options with the default mode changed to require. Added pg_sslrootcert parameter for setting a custom root certificate and the pg_insecure parameter is no longer supported.

Databricks Connect: Choose between using Spark Connect or Delta Lake when using the Databricks data connector for improved performance.

Improved SSL support for Postgres: ssl mode now supports disable, require, prefer, verify-ca, verify-full options with default mode changed to require. Added pg_sslrootcert parameter to allow setting custom root cert for postgres connector, pg_insecure parameter is no longer supported as redundant.
