TTL for what ?
for hive queries or hive over thrift or anything else you have in mind?
for query execution they can run by default till the time map-reduce runs. On Thu, Nov 29, 2012 at 5:09 PM, Hezhiqiang (Ransom) < [EMAIL PROTECTED]> wrote:

Hi Nitin
TTL for data alive in hive. Can hive automatically delete data when out of date?

hive will not delete anything unless you ask for it
if your tables are on hdfs tmp folder, hadoop will wipe them off if you dont use them for the tmp time period. If you want to delete data from tables or complete tables, you will need to schedule crons or look at few workflow engines
I may be wrong but I never saw anything got auto deleted in hive unless asked to be deleted manually On Thu, Nov 29, 2012 at 5:27 PM, Hezhiqiang (Ransom) < [EMAIL PROTECTED]> wrote:

their is a table level property retention it does not do anything but you can write a program to sweep through the metastore and take action based on that or other custom properties.
