dumpReCreateStatements

public static java.util.List<java.lang.String> dumpReCreateStatements(TableMetadata metadata)

getTableMetadataAsCQL

public static java.lang.String getTableMetadataAsCQL(TableMetadata metadata,
                                                     boolean includeDroppedColumns)

Build a CQL String representation of Table Metadata

getUserTypesAsCQL

public static java.util.List<java.lang.String> getUserTypesAsCQL(TableMetadata metadata)

Build a CQL String representation of User Types used in the given Table. Type order is ensured as types are built incrementally: from the innermost (most nested) to the outermost.

getDroppedColumnsAsCQL

public static java.util.List<java.lang.String> getDroppedColumnsAsCQL(TableMetadata metadata)

Build a CQL String representation of Dropped Columns in the given Table. If the column was dropped once, but is now re-created `ADD` will be appended accordingly.

getIndexesAsCQL

public static java.util.List<java.lang.String> getIndexesAsCQL(TableMetadata metadata)

Build a CQL String representation of Indexes on columns in the given Table

isCqlCompatible

public static boolean isCqlCompatible(TableMetadata metaData)

Whether or not the given metadata is compatible / representable with CQL Language
