Hi All,

If we have a table and btree index on it.
I would like to know what specific files and functions are called to insert
data into index whenever I want to insert data into a table.

For example, if I insert a anew row into a table, then a new row in index
will be inserted. I would like to know the sequential flow of functions or
files called to insert data into a btree.

Please give me the flow for both an empty btree or an existing btree with
(key, value) pairs.
