recap add my_hms thrift+hms://hive:password@localhost:9083

Environment Variables

export RECAP_SYSTEM__MY_HMS=thrift+hms://hive:password@localhost:9083

Python API

from recap.clients import create_client

with create_client("thrift+hms://hive:password@localhost:9083") as client:"testdb")



Recap’s Hive Metastore client takes the Thrift URL to the Hive Metastore.

The scheme must be thrift+hms. The +hms suffix is required to distinguish this client from other clients that also use Thrift connections (similar to SQLAlchemy’s dialect+driver format)


Recap’s Confluent Schema Registry paths are formatted as:

Limitations and Constraints

The conversion functions raise a ValueError exception if the conversion is not possible.
