What's Wrong?

I run a file with python many times, it create many MetaStoreProvider-created-19??? directories

How to Reproduce?

create the /par/config2.toml.txt with below

[meta]
embedded_dir = "/par/"

# Storage config.
[storage]
# fs | s3 | azblob | obs | oss
type = "fs"
allow_insecure = true

[storage.fs]
data_path = "/par/"
allow_insecure = true

and q1.py with below

```python
import databend
databend.init_service( config = "/par/config2.toml.txt" )
from databend import SessionContext
ctx = SessionContext()
ctx.register_parquet("lineitem", "/par/fire/data/tables_pyarrow/scale-10.0/", pattern = "lineitem.parquet") #only once
df = ctx.sql("select count(*) from lineitem")
df.show()

then run python q1.py
BTW if I run it the file the second time
it reports
RuntimeError: DataFrame collect error: ViewAlreadyExists. Code: 2306, Text = 'lineitem' as view Already Exists.
I had to coment out the ctx.register_parquet line to run q1.py
