Locking tables/projections while creating design
I have a question about locking tables/queries.
1. Does Vertica lock some tables or projections during process of designing new projections (programatically or with DBDesigner in Admintools)? Here I mean the tables/projections which are involved in new design. I have a suspicion that during the proces of designing the original tables/projections must be in consistent state, so the content of tables/projection is during the design the same all the time (it means that the tables/projections are read-only). The problem is that it isn't possible to write to the database during the time of designing.
2. Is there any way to observe it in log files? I went through vertica.log but there was nothing about locking tables/projections.
3. Is there any way to get round the locking? I would like to work normally (write, update) with database also during the process of designing.
I hope that the questions are clear. If not, I specify it more.
Thank you for your advices.
