Method Detail

getTypeFactory

JavaTypeFactory getTypeFactory()

getRootSchema

CalciteSchema getRootSchema()

Returns the root schema for statements that need a read-consistent snapshot.

getMutableRootSchema

CalciteSchema getMutableRootSchema()

Returns the root schema for statements that need to be able to modify schemas and have the results available to other statements. Viz, DDL statements.

getDefaultSchemaPath

List<String> getDefaultSchemaPath()

config

CalciteConnectionConfig config()

spark

CalcitePrepare.SparkHandler spark()

Returns the spark handler. Never null.

getDataContext

DataContext getDataContext()

getObjectPath

@Nullable List<String> getObjectPath()

Returns the path of the object being analyzed, or null.

The object is being analyzed is typically a view. If it is already being analyzed further up the stack, the view definition can be deduced to be cyclic.

getRelRunner

RelRunner getRelRunner()

Gets a runner; it can execute a relational expression.
