Data write into Iceberg Glue Table (saveAsTable vs option("path", s3_output_path))

Question

I am exploring data write into glue Table (Iceberg Table format). I have been using saveAsTable method mentioned as option1 . However is there any difference between two methods. Iceberg stores metadata in s3. Is wrtiting to path will not alow to update partitions in. glue metastore? I am using emr to write to data into s3.

result_df.write \
 .mode("overwrite") \
 .format("iceberg") \
 .option("write-format", "parquet") \
 .option("fanout-enabled", "false") \
 .option("format-version", "2") \
 .option("write.distribution-mode", "hash") \
 .option("write.merge.mode", "copy-on-write") \
 .partitionBy("source", "region", "country", "dataset_date") \
 .saveAsTable("your_database.your_table")
Or for path-based table:
result_df.write \
 .mode("overwrite") \
 .format("iceberg") \
 .option("path", s3_output_path) \
 .option("write-format", "parquet") \
 .option("fanout-enabled", "false") \
 .option("format-version", "2") \
 .option("write.distribution-mode", "hash") \
 .option("write.merge.mode", "copy-on-write") \
 .partitionBy("source", "region", "country", "dataset_date") \
 .save()
