Hi [~tarmstrong],[~boroknagyz],[~vihangk1], I have already completed a version of query iceberg table by impala. The main design is treated iceberg table as an unpartitioned hdfs table, including theses functions:
# identity iceberg file format by table property;
# push down iceberg partition column predicates to iceberg, to filter data files need to be scanned;
This is a simple version, and some code may be not good, hope you can give some advice, thanks a lot.
