I was working on star tree indexing. While loading the data, I got the following issue. Table and schemas are attached with this thread. I was trying to load 30 records. One of the column of star tree index is MSISDN and its cardinality: 10 also TARIFF_PLAN with cardinality: 5

star tree doesn’t work for Multi Value columns. Sorry about the error not being more explicit, we’re adding it to our validations when creating the table. Could you try without the TARIFF_PLAN multi value column?

also dont forget to add the time column in the split order
