[I] Using subdirectory to dave data in ICEBERG. [iceberg]
moweonlee opened a new issue, #10327:
URL: https://github.com/apache/iceberg/issues/10327
### Query engine
Spark - pyspark
### Question
We have stored our data in HDFS into subdirecties for every hour with batch processing .
Here are the examples to show how we write data in HDFS for every hours.
- hdfs://team/data/logtype_a/2024/05/01/00
- hdfs://team/data/logtype_b/2024/05/01/01
We have many data applications that uses that directories as input for long time.
And it's practically hard to change input directory in applications that uses directories.
But anyway I'd like to use ICEBERG with that data with metadata location "hdfs://team/data/rawlog/metadata".
Because we'd like to read whole data as single table. ( from Starrocks )
So my question is "Can I load data for every hours with single metadata location"
We uses PySpark to load data.
And here is example code that loads data.
```
df\
.writeTo(tableName) \
.tableProperty("write.data.path" ,"hdfs://team/data/logtype_a/" + datePath + "/" + hour + "/") \
.tableProperty("write.metadata.path" ,"hdfs://team/data/logtype_a/" ) \
.option("mergeSchema","true") \
.append()
```
