------------------------------------------
Summary: Parquet Or ORC
Key: HIVE-18810
URL: https://issues.apache.org/jira/browse/HIVE-18810
Project: Hive
Issue Type: Test
Components: Hive
Affects Versions: 1.1.0
Environment: Hadoop 1.2.1
Hive 1.1
Reporter: Suddhasatwa Bhaumik
Hello Experts,
I would like to know for which data types (based on size and complexity of
data) should one be using Parquet or ORC tables in Hive. E.g., On Hadoop 0.20.0
with hive 0.13, the performance of ORC tables in Hive is very good when
accessed even by 3rd party BI systems like SAP Business Objects or Tableau;
performing the same tests on Hadoop 1.2.1 with Hive 1.1 does not yield such
reliability in queries, although ETL or insert/update of tables are taking
nominal time the read performance is not within acceptable limits.
In case of any queries, kindly advise.
Thanks
