[Herddb-dev] Question file storage.

Hello,

I was playing around with herddb to do some testing today. I create a very
simple table ./herddb-cli.sh -q "CREATE TABLE amit(id int primary key, name
string)". I see table meta data file, txlog file etc created for this
table. I also inserted 2 to 3 rows into this table and I am able to see the
txlog being appended by the transaction. What I don't see is the data
actually being written to the disk for the table. The directory
*dbdata/data/20017d0222784757b504d0a157c59333.tablespace/fa077872-98c2-495d-8891-75936baa3a40.table
*is empty. When does the in-memory data get written to the disk? Is there a
setting or does it occur during checkpoint ?

Thanks,
Amit
