I'm thinking of using Cassandra for a large data project. Data will be taken from traditional data warehouse. Cassandra will host data in a way that my application can read it correctly.
I do not quite understand how I will sort data from Kaisandra. For example, I have to count the number of visits, special IP address has been planning to create this data every 24 hours on the website and I want to keep 2 IP addresses per week. My column structure looks like this: <127> P> How to remove at least rows from visitors?
So far, the best solution I have taken is this:
- Find the column I want to work with
- Prices
- Re-insert new sliced column
This is like a bad method Seems to work with the database, I agree that my figure size will be balloon, the basis of the way storage is done in Cassandra Su.
Is there a more efficient way to do this?
I am currently working with my interface.
Thank you!
You do not really want to delete and rewrite the entire column, assuming that you have a supercompany here Using, you can only remove a specific key from within the supercoll (in this case the visitor last 24 hours). You will cross specific key values within the supercomputer, which are older than your cutoff time, and remove each of them. Every time you add or sub-line with a supercool, you do not have to rewrite the entire dataset. Items of Interest: Fragmentation and Deletion.
