From f1b18bafe4896866874ac578bf16352452d913ea Mon Sep 17 00:00:00 2001 From: Jack Ye Date: Sat, 23 Aug 2025 21:33:10 -0700 Subject: [PATCH 1/7] feat: add Polaris Catalog namespace implementation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add support for Polaris Catalog integration using the Generic Table API. This follows the same pattern as Unity Catalog implementation. - Implement PolarisNamespace with full namespace and table operations - Use RestClient from lance-namespace-core for HTTP communication - Support bearer token authentication - Map Polaris Generic Table API to Lance namespace interface - Add comprehensive documentation in docs/src/impls/polaris.md - Include unit tests with mocked RestClient The implementation allows Lance tables to be managed alongside other table formats (Iceberg, Delta) in Polaris Catalog. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- docs/src/impls/polaris.md | 192 +++++++ java/lance-namespace-polaris/README.md | 77 +++ java/lance-namespace-polaris/pom.xml | 78 +++ .../namespace/polaris/PolarisModels.java | 416 ++++++++++++++ .../namespace/polaris/PolarisNamespace.java | 507 ++++++++++++++++++ .../polaris/PolarisNamespaceConfig.java | 137 +++++ .../polaris/TestPolarisNamespace.java | 352 ++++++++++++ java/pom.xml | 1 + 8 files changed, 1760 insertions(+) create mode 100644 docs/src/impls/polaris.md create mode 100644 java/lance-namespace-polaris/README.md create mode 100644 java/lance-namespace-polaris/pom.xml create mode 100644 java/lance-namespace-polaris/src/main/java/com/lancedb/lance/namespace/polaris/PolarisModels.java create mode 100644 java/lance-namespace-polaris/src/main/java/com/lancedb/lance/namespace/polaris/PolarisNamespace.java create mode 100644 java/lance-namespace-polaris/src/main/java/com/lancedb/lance/namespace/polaris/PolarisNamespaceConfig.java create mode 100644 java/lance-namespace-polaris/src/test/java/com/lancedb/lance/namespace/polaris/TestPolarisNamespace.java diff --git a/docs/src/impls/polaris.md b/docs/src/impls/polaris.md new file mode 100644 index 000000000..01995bfe3 --- /dev/null +++ b/docs/src/impls/polaris.md @@ -0,0 +1,192 @@ +# Polaris Namespace + +The Polaris namespace implementation provides integration between Lance and [Polaris Catalog](https://github.com/polaris-catalog/polaris) using the Generic Table API. + +## Overview + +Polaris Catalog is an open-source catalog implementation that provides a REST API for managing tables and namespaces.
