}

Notes:

We wanted to have package wildcards in typeName. E.g. "org.my.package.*". This is prone to errors and it is better to allow user select whether this is config for a single type or for a package explicitly;
TypeInfo's are set as varargs to follow general Ignite rules (e.g. IgniteConfiguration.setCacheConfiguration()).
TypeInfo getter/setter do not have "s" at the end to follow general Ignite rules (e.g. IgniteConfiguration.setCacheConfiguration());
Shouldn't we move "affKeyFieldName" to another TypeInfo, e.g. AffinityKeyTypeInfo?

TypeInfo

Code Block

language	java

public interface TypeInfo extends Serializable {
    /** Whether implemenation supports single type. */
    bool supportSingleType();
 
    /** Whether implementation supports multiple packagestypes. */
    bool supportPackagesupportMultipleTypes();
}

Notes:

Package configuration are only supported by PortableTypeInfo for now. For this reason it makes sense to add "support*" methods to prevent misconfiguration.

Package wildcards are not supported.

PortableTypeInfo

Notes:

Supported for both types and package wildcards.

QueryTypeInfo

    /** Fields to index as text. */
    private String[] txtIdxs;    
}

    NONE,
 
    /** Ascending order. */ 
    ASC,

    @GridToStringInclude
    private Map<String, Class<?>> descFlds;

    /** Fields to index as textprivate QueryFieldInfo[] flds;
}

Notes

QueryFieldInfo.cls is a problem for non-Java users, because they have to write ugly things like "java.lang.Integer" which is very hard to understand for non-Java users. Lets switch to enum here?
