Announcing the release of Spice v1.5.1! 🔑

Spice v1.5.1 expands the GitHub data connector to include pull-request comments, adds a configurable rate limiting for AWS Bedrock embedding models, expands partition pruning with inequality operators, and adds client-supplied cache keys for granular caching control in the HTTP and Arrow Flight SQL APIs.

What's New in v1.5.1​

GitHub Data Connector Pull Request Comments: Configure GitHub pulls datasets to include comments.

Example Spicepod.yaml:

datasets:
  - from: github:github.com/spiceai/spiceai/pulls
    name: spiceai.pulls
    params:
      github_include_comments: all # 'review', 'discussion', or 'none'. Defaults to 'none'.
      github_max_comments_fetched: '25' # Defaults to 100
      # ...

For details, see the GitHub Data Connector documentation.

AWS Bedrock Embedding Models Invocation Control: Improved rate limiting control for AWS Bedrock embedding models with max_concurrent_invocations configuration.

embeddings:
  - from: bedrock:cohere.embed-english-v3
    name: cohere-embeddings
    params:
      max_concurrent_invocations: '41'
      # ...

For details, see the AWS Bedrock Embeddings Model Provider documentation.

Improved Query Partitioning: Expanded partition pruning support with additional inequality operators (e.g. >, >=, <, <=).

For details, see the Query Partitioning documentation.

Client-Supplied Cache Keys: Support for a new Spice-Cache-Key header/metadata-key in the HTTP and Arrow Flight SQL query APIs to for fine-grained client-side caching control.

Example HTTP API usage:

$ curl -vvS -XPOST http://localhost:8090/v1/sql \
-H"spice-cache-key: 1851400_20170216_north_america" \
-d "select * from scihub_journals_accessed
    where user_id = '1851400'
      and date_trunc('DAY', timestamp) = '2017-02-16'
      and city = 'New York';"

Example Response:

< HTTP/1.1 200 OK
< content-type: application/json
< x-cache: Hit from spiceai
< results-cache-status: HIT
< vary: Spice-Cache-Key
< vary: origin, access-control-request-method, access-control-request-headers
< content-length: 604
