HWM -Direct Path loads

edited Apr 26, 2017 5:00AM in Exadata General (MOSC) 3 commentsAnswered

I have hundreds of tables with data retention period  ranging from 1 week to maximum of 3 weeks. Data load into these tables would be from direct path load to achieve compression.

I am planning to interval partition these tables with 7 days per interval. If i choose single tablespace to accommodate all partitions:

Q:  When i drop partitions after retention period, would the newer data be loaded below the HWM ? (Using HWMB)

Q: Would my parallel inserts take conventional path insert to load the data below HWM in the tablespace? Or is it advised to map partitions to different tablespaces( week 1 data to tablspace 1; week 2 to tablspace 2 ) so that when i drop week 1 data from tablespace 1 , The HWM of it would brought down and ready for next month's week 1 data.

Howdy, Stranger!
