forExistingTable

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

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, boolean) and getPartitionWriteInfo(LocationHandle, Optional, String) method.

getTableWriteInfo

LocationService.WriteInfo getTableWriteInfo(LocationHandle locationHandle,
                                            boolean overwrite)

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.
