I did not reproduce it.

import databend

databend.init_service(config = """
[storage]
# fs | s3 | azblob | obs | oss
type = "fs"
allow_insecure = true
[storage.fs]
data_path = "/par"
allow_insecure = true
""")


# databend.init_service(local_dir = "/tmp/abc")
from databend import SessionContext
ctx = SessionContext()
ctx.register_parquet("lineitem", "/home/sundy/tmp/", pattern = "*.parquet")
ctx.sql("select * from lineitem").show()

outputs:

>>> ctx.sql("select * from lineitem").show()
