Add ibis_extras package with SingleStoreDB Ibis backend extensions#120
Conversation
Add mixin classes that extend the Ibis SingleStoreDB backend and ir.Table with SingleStoreDB-specific functionality: - BackendExtensionsMixin: variable/show accessors (globals, locals, cluster_globals, cluster_locals, vars, cluster_vars, show), plus get_storage_info(), get_workload_metrics(), optimize_table(), and get_table_stats() methods - TableExtensionsMixin: optimize(), get_stats(), and get_column_statistics() methods for SingleStoreDB tables The mixins are automatically registered on import via dynamic base class injection. Protocol classes are used for type checking to satisfy mypy while keeping runtime behavior unchanged. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Pull request overview
This PR adds a new ibis_extras package that extends the Ibis SingleStoreDB backend with SingleStoreDB-specific functionality through mixin classes that are automatically injected into the backend and table classes at import time.
Changes:
- Adds
BackendExtensionsMixinwith variable/show accessors and new methods for storage info, workload metrics, table optimization, and statistics - Adds
TableExtensionsMixinwith table-specific methods for optimization, statistics, and column statistics - Implements automatic mixin registration via dynamic base class modification

- Add error handling for optional ibis imports with informative message - Remove sqlglot dependency, use backtick quoting for identifiers - Fix database context assumption in table methods by extracting database from table's namespace metadata - Table methods now correctly pass database to backend methods Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Update _get_table_backend_and_db() to always return resolved database
name with optional escape parameter ('identifier', 'literal', or None)
- Move optimize_table() implementation to TableExtensionsMixin.optimize()
- Move get_table_stats() implementation to TableExtensionsMixin.get_stats()
- Simplify get_column_statistics() to use new escape parameter
- Remove optimize_table() and get_table_stats() from BackendExtensionsMixin
- Update __init__.py docstring to remove backend method reference

Return ir.Table instead of dict to match get_storage_info() and get_column_statistics(). This provides lazy evaluation and lets users work with the data however they prefer. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
