one meta transaction.
Vladimir Ozerov created IGNITE-2824:
---------------------------------------
Summary: IGFS: File close should require only one meta transaction.
Key: IGNITE-2824
URL: https://issues.apache.org/jira/browse/IGNITE-2824
Project: Ignite
Issue Type: Bug
Components: IGFS
Affects Versions: 1.5.0.final
Reporter: Vladimir Ozerov
Fix For: 1.6
*Problem*
Have a look at {{IgfsOutputStreamImpl.onClose(boolean)}} method. It performs two sequential calls:
1) meta.unlock();
2) meta.updateParentListingAsync().
It spans two transactions and hence two 2PC routines, leading to less than optimal performance.
*Solution*
Update both file and it's parent in a single transaction.
