Is the index created as soon as data is inserted into a table?












0















For example I have a table and I created an index on ID column which generates numbers every time I insert a row. If I only insert 5 rows does index tree start to be created or is there a threshold of pages or rows that should be reached before the index tree is built?

          You don't say what DBMS you're using, so it is possible yours does not. The majors, however, will maintain the table and indexes as completely consistent at all times.
