The v0.13.2-alpha release is focused on quality and stability with improvements to federated query push-down, telemetry, and query history.

Highlights​

• Filesystem Data Connector: Adds the Filesystem Data Connector for directly using files as data sources.

• Federated Query Push-Down: Improved stability and schema compatibility for federated queries.

• Enhanced Telemetry: Runtime Metrics now include last update time for accelerated datasets, count of refresh errors, and new metrics for query duration and failures.

• Query History: Enabled query history logging for Arrow Flight queries in addition to HTTP queries.

The v0.13.1-alpha release of Spice is a minor update focused on stability, quality, and operability. Query result caching provides protection against bursts of queries and schema support for datasets has been added logical grouping. An issue where Refresh SQL predicates were not pushed down underlying data sources has been resolved along with improved Acceleration Refresh logging.

Highlights in v0.13.1-alpha​

• Results Caching: Introduced query results caching to handle bursts of requests and support caching of non-accelerated results, such as refresh data returned on zero results. Results caching is enabled by default with a 1s item time-to-live (TTL). Learn more.

• Query History Logging: Recent queries are now logged in the new spice.runtime.query_history dataset with a default retention of 24-hours. Query history is initially enabled for HTTP queries only (not Arrow Flight queries).

• Dataset Schemas: Added support for dataset schemas, allowing logical grouping of datasets by separating the schema name from the table name with a .. E.g.

  datasets:
    - from: mysql:app1.identities
      name: app.users
  
    - from: postgres:app2.purchases
      name: app.purchases
  

  In this example, queries against app.users will be federated to my_schema.my_table, and app.purchases will be federated to app2.purchases.

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.

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.

Highlights​

• 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.

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.
