azure - U-SQL error while table rebuild -

-



error occurs when call alter table rebuild in 1 stored procedure , try select data in simultaneously.

create procedure if not exists rebuildcontent()   begin   insert dbo.log (date, message) values ( datetime.utcnow, "starting content table rebuilding ..." );  alter table dbo.content rebuild;  alter table dbo.contentcrc rebuild;  insert dbo.log (date, message) values ( datetime.utcnow, "completed content table rebuilding ..." );  end;

enter image description here

are there solutions avoid it? thank in advance!

you running race condition between rebuilding , reading same table.

rebuilding table creates new file compacting files got created insertion. unfortunately right now, once rebuild deleting old file, lose access old version , error message.

we aware of issue , have created work item preserve access old file started queries (providing snapshot semantics). however, not have eta @ moment.

thus until then, please schedule rebuild , read jobs without overlaps.

note: can still concurrently rebuild , insert or insert , read.
