Thanks "for the best".
Thats the way it is.performing one command (like xquery, add, delete etc.)
This would be the best
Note that all commands are atomic transactions, like a alter database -> closes the database,
renames it and reopens it...but you havent care about that.
Kind regards and happy new year (with BaseX),
Andreas

What are starting/ending points of one transaction
- creating connection - closing it.
probably not- open database - close
??- performing one command (like xquery, add, delete etc.)

Hi Jan,
if a writing or reading transaction is active, all new incoming transactions are stored in
a waiting queue.
So all writing transactions will be processed in first come - first server order.
Reading transactions are processed concurrently.
Transactions will no be rejected at any time.
Kind regards,
Andreas

one collection can be written/modified only by one process at given moment, other attempts to write are rejected and these attempts will fail.
In other words - one collection can be opened only by one process (or are multiple opening clients allowed as long as the do not modify database concurrently?)
