Spice v2.1.4 (Aug 5, 2026)

Spice v2.1.4 is now available! 🛠️

Spice v2.1.4 is a patch release that improves DuckDB acceleration and runtime stability: datasets with UTC timestamp columns, such as Iceberg tables, now load successfully when accelerated with DuckDB, retention policies run reliably, and the runtime is more resilient under heavy query load.

What's New in v2.1.4​

DuckDB Acceleration Works with Iceberg Timestamps​

A dataset with a UTC timestamp column — for example, any Iceberg timestamptz column — could previously fail to load when accelerated with DuckDB, leaving the dataset unhealthy and unqueryable. These datasets now load and become ready normally, with no configuration changes needed.

Reliable Retention Policies on DuckDB​

Retention policies now apply cleanly on DuckDB-accelerated datasets, including policies that combine a time window with an additional condition. Expired rows are evicted on every retention interval, keeping accelerated data fresh and storage bounded.

Improved Runtime Stability​

The runtime is now more robust when queries are cancelled — whether by a client disconnecting, a timeout, or a new refresh superseding an in-flight read. A rare crash in this path has been eliminated.

The v0.13.3-alpha release is focused on quality and stability with improvements to metrics, telemetry, and operability.

Highlights​

Ready API: - Add /v1/ready API that returns success once all datasets and models are loaded and ready.

Enhanced Grafana dashboard: The dashboard now includes charts for query duration and failures, the last update time of accelerated datasets, the count of refresh errors, and the last successful time the runtime was able to access federated datasets

Spice v0.13.1-alpha (May 27, 2024)

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.
