Hi @nsivabalan,
I built a job that runs below code periodically to refresh a table:
```
val df = sc.read.load("s3://some_bucket/some_folder/*.parquet")
df.write.format("hudi").
option("hoodie.datasource.write.operation","insert_overwrite_table").
option("hoodie.datasource.write.precombine.field", "ts_ms").
option("hoodie.datasource.write.recordkey.field", "some_key").
option("hoodie.table.name", "test_table").
mode("Append").
save("s3://some_bucket/output_folder/output/")
```
I noticed on each run, it keeps adding more parquet files to the output
folder. Not sure why that's happening. The data wasn't changing in the source
dataframe before writing.
Am I doing something wrong here?
The goal is to refresh existing partitioned parquet files atomically.
Thank you
