Class MetadataAPIHelper.ShowColumnsInfo

java.lang.Object

com.amazon.redshift.jdbc.MetadataAPIHelper.ShowColumnsInfo

Enclosing class:

MetadataAPIHelper

public static class MetadataAPIHelper.ShowColumnsInfo
extends Object

Data container for column metadata returned by the SHOW COLUMNS command.

This class represents comprehensive column information including standard SQL metadata (name, type, nullability, defaults) and Redshift-specific attributes (sort keys, distribution keys, encoding). Used by JDBC metadata methods like getColumns() to provide structured access to column information.

Redshift-specific fields include:

• sortKeyType/sortKey: Column's role in table sorting
• distKey: Whether column is used for data distribution
• encoding: Column compression encoding (e.g., LZO, DELTA)
