Posted by What’s a heap table? I would say it’s a table without clustered index.
What’s the characteristic of a heap table? The data isn’t ordered.
What’s the consequence having a heap table? There are a few:
- Specific data is not retrived quickly
- Data pages aren’t linked, that means sequential access needs to refer to the index allocation map (IAM) pages
- No cost to update indexes
- No additional space to store clustered index
I believe you have remarked some very interesting details , thanks for the post.
