----------------------------------
Summary: Hive column update performance too low when table
partition over 700
Key: HIVE-25730
URL: https://issues.apache.org/jira/browse/HIVE-25730
Project: Hive
Issue Type: Bug
Components: Metastore
Affects Versions: 3.1.1
Reporter: JungHyun An
Fix For: 3.1.1
Hi, we using hive 3.1.1
Currently in our hive have tables with hundreds of partitions and hundreds of
gigabytes of data.
When updating the column information of the corresponding table, it was
confirmed that the performance was several tens of times slower than the Hive
1.1 version of the older CDH.
I would like to ask if there is any architectural change that makes column
updates slower than Hive 1 in Hive 3 and later versions.
Thank you.
