Package org.apache.ignite.catalog.definitions

Class ZoneDefinition

java.lang.Object
org.apache.ignite.catalog.definitions.ZoneDefinition
public class ZoneDefinition extends Object
Definition of the CREATE ZONE statement.

The zone name is an SQL identifier expression, read exactly the way CREATE ZONE reads it: an unquoted name is folded to upper case, so builder("myZone") and builder("MYZONE") name the same zone; a double-quoted name is taken literally, so builder("\"myZone\"") names a case-sensitive zone. A name that is not a valid SQL identifier is rejected.

The built-in default zone is stored mixed-case, as Default, so naming it takes quotes as well: "\"Default\"", the value of Table.DEFAULT_ZONE. An unquoted Default names the zone DEFAULT instead.
