Hi folks
I have two questions related to columnar table definition.
1. What is the purpose of column store type.
While defining a columnar table, what is the purpose of column store type (STRING ,CS_FIXEDSTRING,CS_INT etc) , when I define a table using the UI I see that the column is showing STRING but when I goto EXPORT SQL it does not show. Is this mandatory or optional ?
2.VARCHAR Vs. CHAR - In the UI when I create the table I do not see the CHAR option , but I do see lot of discussion where people are using CHAR for defining the columnar table. Not sure why UI dropdown does not show it. I also read that we should avoid using VARCHAR as those columns are not compressed, is that true, I thought the column store gives compression for all the columns. Are there certain columns which cannot be compressed .
Please let me know where I can find more information about these two questions.
