Spice v0.13-alpha (May 20, 2024)

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.


  • 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 v0.12.2-alpha (May 13, 2024)

The v0.12.2-alpha release introduces data streaming and key-pair authentication for the Snowflake data connector, enables general append mode data refreshes for time-series data, improves connectivity error messages, adds nested folders support for the S3 data connector, and exposes nodeSelector and affinity keys in the Helm chart for better Kubernetes management.


  • Improved Connectivity Error Messages: Error messages provide clearer, actionable guidance for misconfigured settings or unreachable data connectors.

  • Snowflake Data Connector Improvements: Enables data streaming by default and adds support for key-pair authentication in addition to passwords.

  • API for Refresh SQL Updates: Update dataset Refresh SQL via API.

  • Append Data Refresh: Append mode data refreshes for time-series data are now supported for all data connectors. Specify a dataset time_column with refresh_mode: append to only fetch data more recent than the latest local data.

  • Docker Image Update: The spiceai/spiceai:latest Docker image now includes the ODBC data connector. For a smaller footprint, use spiceai/spiceai:latest-slim.

  • Helm Chart Improvements: nodeSelector and affinity keys are now supported in the Helm chart for improved Kubernetes deployment management.

Breaking Changes

  • API to trigger accelerated dataset refreshes has changed from POST /v1/datasets/:name/refresh to POST /v1/datasets/:name/acceleration/refresh to be consistent with the Spicepod.yaml structure.

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

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.


  • 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.

Spice v0.12-alpha (Apr 29, 2024)

The v0.12-alpha release introduces Clickhouse and Apache Spark data connectors, adds support for limiting refresh data periods for temporal datasets, and includes upgraded Spice Client SDKs compatible with Spice OSS.


  • Clickhouse data connector: Use Clickhouse as a data source with the clickhouse: scheme.

  • Apache Spark Connect data connector: Use Apache Spark Connect connections as a data source using the spark: scheme.

  • Refresh data window: Limit accelerated dataset data refreshes to the specified window, as a duration from now configuration setting, for faster and more efficient refreshes.

  • ODBC data connector: Use ODBC connections as a data source using the odbc: scheme. The ODBC data connector is currently optional and not included in default builds. It can be conditionally compiled using the odbc cargo feature when building from source.

  • Spice Client SDK Support: The official Spice SDKs have been upgraded with support for Spice OSS.

Breaking Changes

  • Refresh interval: The refresh_interval acceleration setting and been changed to refresh_check_interval to make it clearer it is the check versus the data interval.


New Contributors

  • Thanks to @mach-kernel who made their first contribution in #1204 by adding the ODBC data connector!
