How to save space in Vertica Tables?
I am new in Vertica DB and i haven't all the concepts in mind.
We have some tables with important fields and non-important field, the importants fields must be conserved 20 years the non-important fields must be conserved only 5 years.
We don't want modify our table structure and we want to stock all the data in the same tables.
My question is, if we make and UPDATE of the historic (+5 years old data) non-important fields to VOID, NULL, '' or O we could save some space in disk. In theory to have few volatility in the possible value of the fields allow a better compression.
This is right?
In ours tables the 40% of the fiels are important and the 60% non important.
Thanks in advance,
