Protocols Thrift

Official Python client PyStellarDB is built on PyHive and connects with host/port arguments matching HiveServer2's default Thrift port (10000); Transwarp's official docs also list a JDBC SDK access page, but that site is JS-rendered and its body text could not be fetched to quote.

  • PyStellarDB is a Python API for executing Transwarp Exetended OpenCypher(TEoC) and Hive query. It could also generate a RDD object which could be used in PySpark.
