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\""
}

For details, see the SQL Query API and NSQL API documentation.

Spice v1.1.1 (Apr 7, 2025)

· 6 min read

Co-Founder and CTO of Spice AI

Announcing the release of Spice v1.1.1! 📊

Spice v1.1.1 introduces several key updates, including a new Component Metrics System, improved Delta Data Connector performance, improved MCP tool descriptions, and expanded runtime results caching options. This release also adds detailed MySQL connection pool metrics for better observability. Component Metrics are Prometheus-compatible and accessible via the metrics endpoint.

Highlights v1.1.1​

  • Component Metrics System: A new system for monitoring components, starting with MySQL connection pool metrics. These metrics provide insights into MySQL connection performance and can be selectively enabled in the dataset configuration. Metrics are exposed in Prometheus format via the metrics endpoint.

For more details, see the Component Metrics documentation.

  • Results Caching Enhancements: Added a cache_key_type option for runtime results caching. Options include:
    • plan (Default): Uses the query's logical plan as the cache key. Matches semantically equivalent queries but requires query parsing.
    • sql: Uses the raw SQL string as the cache key. Provides faster lookups but requires exact string matches. Use sql for predictable queries without dynamic functions like NOW().

Example spicepod.yaml configuration:

runtime:
  results_cache:
    enabled: true
    cache_max_size: 128MiB
    cache_key_type: sql # Use SQL for the results cache key
    item_ttl: 1s

For more details, see the runtime configuration documentation.

  • Delta Data Connector: Improved scan performance for faster query performance.

  • MCP Tools: Improved descriptions for built-in MCP tools to improve usability.

  • MySQL Component Metrics: Added detailed metrics for monitoring MySQL connections, such as connection count and pool activity.

Example spicepod.yaml configuration:

datasets:
  - from: mysql:my_table
    name: my_dataset
    metrics:
      - name: connection_count
        enabled: true
      - name: connections_in_pool
        enabled: true
      - name: active_wait_requests
        enabled: true
    params:
      mysql_host: localhost
      mysql_tcp_port: 3306
      mysql_user: root
      mysql_pass: ${secrets:MYSQL_PASS}

For more details, see the MySQL Data Connector documentation.

  • spice.js SDK: The spice.js SDK has been updated to v2.0.1 and includes several important security updates.

Spice v1.0.7 (Mar 26, 2025)

· 4 min read

Co-Founder and CTO of Spice AI

Announcing the release of Spice v1.0.7 🏎️

Spice v1.0.7 improves memory usage when using DuckDB, improves schema inference performance when using object-store based data connectors, and fixes a bug in Dremio schema inference.

Highlights in v1.0.7​

  • DuckDB Memory Usage: Memory usage when using DuckDB has been significantly improved for data loads and refreshes through expanded use of zero-copy Arrow and multi-threading for data loads. When a duckdb_memory_limit is specified, disk spilling has been improved for greater-than-memory workloads. In addition, a new temp_directory runtime parameter supports storing temporary files to alternative location than the DuckDB data file for higher throughput. For example, temp_directory could be set to a different high-IOPs IO2 EBS volume that is separate from the duckdb_file_path.

    Automated end-to-end tests for the DuckDB Accelerator coverage has been significantly expanded.

    For configuration details, see the documentation for runtime parameters and the DuckDB Data Accelerator.

  • Schema Inference Performance for Object-Store Data Connectors: Schema inference performance has been improved, especially for large numbers of objects (1M+ objects) when using object-store based data connectors by making the object-listing and selection more efficient.

Performance​

When compared to previous versions, Spice v1.0.7 loads DuckDB accelerated datasets significantly faster. When using the TPCH lineitem dataset at Scale Factor 100 (600M rows):

Without Indexes​

5x faster, 28% less memory usage.

v1.0.6 v1.0.7

VersionLoad TimePeak Memory Usage
v1.0.616m 3s32GB
v1.0.73m 149ms24.4GB

With Indexes​

2.5x faster. Higher memory usage in v1.0.7 is due to better resource utilization to achieve faster load times. Use the duckdb_memory_limit parameter to control memory usage.

VersionLoad TimePeak Memory Usage
v1.0.627m 9s50GB
v1.0.711m 30s77GB

v1.0.6 with indexes v1.0.7 with indexes

Spice v0.19.4-beta (Oct 30, 2024)

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

Announcing the release of Spice v0.19.4-beta ☘️

Spice v0.19.4-beta introduces a new localpod Data Connector, improvements to accelerator resiliency and control, and a new configuration to control when accelerated datasets are considered ready.

Highlights in v0.19.4​

localpod Connector: Implement a "tiered" acceleration strategy with a new localpod Data Connector that can be used to accelerate datasets from other datasets registered in Spice.

datasets:
  - from: s3://my_bucket/my_dataset
    name: my_dataset
    acceleration:
      enabled: true
      engine: duckdb
      mode: file
      refresh_check_interval: 60s
  - from: localpod:my_dataset
    name: my_localpod_dataset
    acceleration:
      enabled: true

Refreshes on the localpod's parent dataset will automatically be synchronized with the localpod dataset.

Improved Accelerator Resiliency: When Spice is restarted, if the federated source for a dataset configured with a file-based accelerator is not available, the dataset will still load from the existing file data and will attempt to connect to the federated source in the background for future refreshes.

Accelerator Ready State: Control when an accelerated dataset is considered "ready" by the runtime with the new ready_state parameter.

datasets:
  - from: s3://my_bucket/my_dataset
    name: my_dataset
    acceleration:
      enabled: true
      ready_state: on_load # or on_registration
  • ready_state: on_load: Default. The dataset is considered ready after the initial load of the accelerated data. For file-based accelerated datasets that have existing data, this means the dataset is ready immediately.
  • ready_state: on_registration: The dataset is considered ready when the dataset is registered in Spice. Queries against this dataset before the data is loaded will fallback to the federated source.

Breaking changes​

Accelerated datasets configured with ready_state: on_load (the default behavior) that are not ready will return an error instead of returning zero results.

Co-Founder and CTO of Spice AI

Announcing the release of Spice v0.17.2-beta 🏄

The v0.17.2-beta release focuses on improving data accelerator compatibility, stability, and performance. Expanded data type support for DuckDB, SQLite, and PostgreSQL data accelerators (and data connectors) enables significantly more data types to be accelerated. Error handling and logging has also been improved along with several bugs.

Highlights in v0.17.2-beta​

Expanded Data Type Support for Data Accelerators: DuckDB, SQLite, and PostgreSQL Data Accelerators now support a wider range of data types, enabling acceleration of more diverse datasets.

Enhanced Error Handling and Logging: Improvements have been made to aid in troubleshooting and debugging.

Anonymous Usage Telemetry: Optional, anonymous, aggregated telemetry has been added to help improve Spice. This feature can be disabled. For details about collected data, see the telemetry documentation.

To opt out of telemetry:

  1. Using the CLI flag:

    spice run -- --telemetry-enabled false

  2. Add configuration to spicepod.yaml:

    runtime:
      telemetry:
        enabled: false

Improved Benchmarking: A suite of performance benchmarking tests have been added to the project, helping to maintain and improve runtime performance; a top priority for the project.

Breaking Changes​

None.

Spice v0.17.1-beta (August 5, 2024)

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

The v0.17.1-beta minor release focuses on enhancing stability, performance, and usability. The Flight interface now supports the GetSchema API and s3, ftp, sftp, http, https, and databricks data connectors have added support for a client_timeout parameter.

Highlights in v0.17.1-beta​

Flight API GetSchema: The GetSchema API is now supported by the Flight interface. The schema of a dataset can be retrieved using GetSchema with the PATH or CMD FlightDescriptor types. The CMD FlightDescriptor type is used to get the schema of an arbitrary SQL query as the CMD bytes. The PATH FlightDescriptor type is used to retrieve the schema of a dataset.

Client Timeout: A client_timeout parameter has been added for Data Connectors: ftp, sftp, http, https, and databricks. When defined, the client timeout configures Spice to stop waiting for a response from the data source after the specified duration. The default timeout is 30 seconds.

  - from: ftp://remote-ftp-server.com/path/to/folder/
    name: my_dataset
    params:
      file_format: csv
      # Example client timeout
      client_timeout: 30s
      ftp_user: my-ftp-user
      ftp_pass: ${secrets:my_ftp_password}

Breaking Changes​

TLS is now required to be explicitly enabled. Enable TLS on the command line using --tls-enabled true:

spice run -- --tls-enabled true --tls-certificate-file /path/to/cert.pem --tls-key-file /path/to/key.pem

Or in the spicepod.yml with enabled: true:

runtime:
  tls:
    # TLS explicitly enabled
    enabled: true
    certificate_file: /path/to/cert.pem
    key_file: /path/to/key.pem

Co-Founder and CTO of Spice AI

Announcing the first beta release of Spice.ai OSS! 🎉

The core Spice runtime has graduated from alpha to beta! Components, such as Data Connectors and Models, follow independent release milestones. Data Connectors graduating from alpha to beta include databricks, spiceai, postgres, s3, odbc, and mysql. From beta to 1.0, project will be to on improving performance and scaling to larger datasets.

This release also includes enhanced security with Transport Layer Security (TLS) secured APIs, a new spice install CLI command, and several performance and stability improvements.

Highlights in v0.17-beta​

  • Encryption in transit with TLS: The HTTP, gRPC, Metrics, and OpenTelemetry (OTEL) API endpoints can be secured with TLS by specifying a certificate and private key in PEM format.

Enable TLS using the --tls-certificate-file and --tls-key-file command-line flags:

spice run -- --tls-certificate-file /path/to/cert.pem --tls-key-file /path/to/key.pem

Or configure in the spicepod.yml:

runtime:
  tls:
    certificate_file: /path/to/cert.pem
    key_file: /path/to/key.pem

Get started with TLS by following the TLS Sample. For more details see the TLS Documentation.

  • spice install: Running the spice install CLI command will download and install the latest version of the runtime.
spice install

  • Improved SQLite and DuckDB compatibility: The SQLite and DuckDB accelerators support more complex queries and additional data types.

  • Pass through arguments from spice run to runtime: Arguments passed to spice run are now passed through to the runtime.

  • Secrets replacement within connection strings: Secrets are now replaced within connection strings:

datasets:
  - from: mysql:my_table
    name: my_table
    params:
      mysql_connection_string: mysql://user:${secrets:mysql_pw}@localhost:3306/db

Breaking Changes​

The odbc data connector is now optional and has been removed from the released binaries. To use the odbc data connector, use the official Spice Docker image or build the Spice runtime from source.

To build Spice from source with the odbc feature:

cargo build --release --features odbc

To use the official Spice Docker image from DockerHub:

# Pull the latest official Spice image
docker pull spiceai/spiceai:latest

# Pull the official v0.17-beta Spice image
docker pull spiceai/spiceai:0.17.0-beta
