getColumnMapping

public static Optional<Map<String,Map.Entry<String,String>>> getColumnMapping(Map<String,Object> tableProperties)

Gets the value of the column_mapping property, or Optional.empty() if not set.

Parses the value into a map of Trino column name to a pair of strings, the Accumulo column family and qualifier.

Parameters:

tableProperties - The map of table properties

Returns:

The column mapping, Trino name to (accumulo column family, qualifier)

getIndexColumns

public static Optional<List<String>> getIndexColumns(Map<String,Object> tableProperties)

getLocalityGroups

public static Optional<Map<String,Set<String>>> getLocalityGroups(Map<String,Object> tableProperties)

Gets the configured locality groups for the table, or Optional.empty() if not set.

All strings are lowercase.

Parameters:

tableProperties - The map of table properties

Returns:

Optional map of locality groups

getRowId

public static Optional<String> getRowId(Map<String,Object> tableProperties)

getScanAuthorizations

public static Optional<String> getScanAuthorizations(Map<String,Object> tableProperties)

getSerializerClass

public static String getSerializerClass(Map<String,Object> tableProperties)

Gets the AccumuloRowSerializer class name to use for this table

Parameters:

tableProperties - The map of table properties

Returns:

The name of the AccumuloRowSerializer class

isExternal

public static boolean isExternal(Map<String,Object> tableProperties)
