git.commit.id.abbrev=240a455

Looking at the below numbers, it looks like we are not doing an incremental update to the cache when the first query is executed after the data has been modified.

{code}
refresh table metadata 1st time : ~45 seconds
select count(*) from lineitem : ~32 seconds
Add a new file to the lineitem folder
select count(*) from lineitem: ~79 seconds
{code}

Query :
{code}

{code}
