Thanks in advance for your insights in to the issues posted. We are in a process of implementing out new data warehouse and most of the tables utilize around 4 or 5 columns defined as Timestamp(6) With Time Zone .
We want to capture all the activity on different entities, hence all our dimensions are INSERT ONLY. The Current Tables has around 20 million records from archive and we anticipate a daily average addition of 100000 rows per table each day.
I am wondering what percentage of the space issue these TimeStamp(6) with Timezone columns contribute ? I learnt that the Timestamp contains
DECIMAL4 seconds SMALLINT year BYTEINT month BYTEINT day BYTEINT hour BYTEINT minute
And I assume storing all that values will take up some considerable amount of space.
Excited to hear some thoughts on this.
