Class SQLContext

crates/integrations/datafusion/src/sql_context.rs:79–84

A SQL context that supports registering multiple Paimon catalogs and executing SQL. # Example ```ignore let mut ctx = SQLContext::new(); ctx.register_catalog("paimon", catalog).await?; ctx.set_current_catalog("paimon").await?; let df = ctx.sql("ALTER TABLE paimon.db.t ADD COLUMN age INT").await?; ```

/// let df = ctx.sql("ALTER TABLE paimon.db.t ADD COLUMN age INT").await?;
/// ```
pub struct SQLContext {
    ctx: SessionContext,
    catalogs: HashMap<String, Arc<dyn Catalog>>,
    /// Session-scoped dynamic options set via `SET 'paimon.key' = 'value'`.
    dynamic_options: DynamicOptions,
}
