Struct AlterSystemStatement 

pub struct AlterSystemStatement {
    pub query_timeout: AlterKind<Expr>,
    pub compact: bool,
}

Alters system-wide settings and maintenance operations.

Supported operations:

• query_timeout: set/drop a global query timeout which is enforced across queries. The value is evaluated as a Duration expression at runtime.
• compact: runs a storage compaction across the entire datastore.

Fields

query_timeout: AlterKind<Expr>

Global query timeout alteration. Set evaluates an expression to a Duration; Drop clears the timeout; None leaves it unchanged.

compact: bool

When true, triggers a datastore-wide compaction.
