Method Detail

forNewTable

LocationHandle forNewTable(SemiTransactionalHiveMetastore metastore,
                           ConnectorSession session,
                           String schemaName,
                           String tableName,
                           boolean tempPathRequired)

forExistingTable

LocationHandle forExistingTable(SemiTransactionalHiveMetastore metastore,
                                ConnectorSession session,
                                Table table,
                                boolean tempPathRequired)

forTemporaryTable

LocationHandle forTemporaryTable(SemiTransactionalHiveMetastore metastore,
                                 ConnectorSession session,
                                 Table table,
                                 boolean tempPathRequired)

getQueryWriteInfo

LocationService.WriteInfo getQueryWriteInfo(LocationHandle locationHandle)

targetPath and writePath will be root directory of all partition and table paths that may be returned by getTableWriteInfo(LocationHandle) and getPartitionWriteInfo(LocationHandle, Optional, String) method.

getTableWriteInfo

LocationService.WriteInfo getTableWriteInfo(LocationHandle locationHandle)

getPartitionWriteInfo

LocationService.WriteInfo getPartitionWriteInfo(LocationHandle locationHandle,
                                                Optional<Partition> partition,
                                                String partitionName)

If partition is present, returns WriteInfo for appending existing partition; otherwise, returns WriteInfo for writing new partition or overwriting existing partition.
