Announcing the release of Spice v1.11.0-rc.3! ⭐

v1.11.0-rc.3 is a patch release that includes improvements to Hash Indexing for Arrow Acceleration and fixes for TLS connections with Flight SQL endpoints.

What's New in v1.11.0-rc.3​

Hash Indexing for Arrow Acceleration (experimental)​

Arrow-based accelerations now support hash indexing for faster point lookups on equality predicates. Hash indexes provide O(1) average-case lookup performance for columns with high cardinality.

Features:

  • Primary key hash index support
  • Secondary index support for non-primary key columns
  • Composite key support with proper null value handling

Example configuration:

datasets:
  - from: postgres:users
    name: users
    acceleration:
      enabled: true
      engine: arrow
      primary_key: user_id
      indexes:
        '(tenant_id, user_id)': unique  # Composite hash index

For more details, refer to the Hash Index Documentation.

Flight SQL TLS Connection Fixes​

TLS Connection Support: Fixed TLS connection issues when using grpc+tls:// scheme with Flight SQL endpoints. Added support for custom CA certificate files via the new flightsql_tls_ca_certificate_file parameter.
