Hi Andreas It seems, like I was too smart (and learned a lot about concurrency in AMQP this very long night) :-)
What are starting/ending points of one transaction
1. creating connection - closing it. probably not 2. open database - close ?? 3. performing one command (like xquery, add, delete etc.) This would be the best

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?)
