Hi, Need some help on a data modelling question. We're using Hector & Datastax Enterprise 2.1.
I want to associate a list of items for a user. It should be sorted on the time added. And items can be updated (quantity of the item can be changed), and items can be deleted. I can model it like this so that its denormalized and I get all my information in one go from one row, sorted by time added. I can use composite columns. Row key: User Id Column Name: TimeUUID:item ID: Item Name: Item Description: Item Price: Item Qty Column Value : Null Now, how do I handle manipulations 1. Add new item :Easy , just a new column 2. Add exiting item or modify qty: I want to get to the correct column to update . Can I search by second column in the composite column (equals condition) & update the column name itself to reflect new TimeUUID and qty? Or would it be better to just add it as a new column and always use the latest column for an item in the application code and delete duplicates in the background. 3. Delete item: Can I search by second column in the composite column to find the correct column to delete? I was trying to find hector examples where we search for second column in a composite column, but I couldn't find any good one. Im not sure if its possible.…if you have any do have any example please share.
