Specified by:

getTypeFactory in interface CalcitePrepare.Context

getRootSchema

public CalciteSchema getRootSchema()

Description copied from interface: CalcitePrepare.Context

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

Specified by:

getRootSchema in interface CalcitePrepare.Context

getMutableRootSchema

public CalciteSchema getMutableRootSchema()

Description copied from interface: CalcitePrepare.Context

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.

Specified by:

getMutableRootSchema in interface CalcitePrepare.Context
