Set<HiveColumnStatisticType> getSupportedColumnStatistics(Type type)

getTableStatistics

PartitionStatistics getTableStatistics(Table table)

getPartitionStatistics

Map<String,PartitionStatistics> getPartitionStatistics(Table table,
 List<Partition> partitions)

void updateTableStatistics(String databaseName,
 String tableName,
 AcidTransaction transaction,
 Function<PartitionStatistics,PartitionStatistics> update)

void updatePartitionStatistics(Table table,
 Map<String,Function<PartitionStatistics,PartitionStatistics>> updates)

getTables

List<String> getTables(String databaseName)

getAllTables

Optional<List<SchemaTableName>> getAllTables()

Returns:

List of tables, views and materialized views names from all schemas or Optional.empty if operation is not supported

getRelationTypes

Map<String,RelationType> getRelationTypes(String databaseName)

getAllRelationTypes

Optional<Map<SchemaTableName,RelationType>> getAllRelationTypes()

Returns:

empty if operation is not supported

getTablesWithParameter

List<String> getTablesWithParameter(String databaseName,
 String parameterKey,
 String parameterValue)

getViews

List<String> getViews(String databaseName)

Lists views and materialized views from given database.

getAllViews

Optional<List<SchemaTableName>> getAllViews()

Returns:

List of views including materialized views names from all schemas or Optional.empty if operation is not supported

createDatabase

void createDatabase(Database database)

dropDatabase

void dropDatabase(String databaseName,
 boolean deleteData)

renameDatabase
