Onderwerp: [firebird-support] Delete causes server to hang
Datum: wo, aug. 24, 2016 22:00

HeyOn my website i have a tabel where i log some web requests - about 
90.000/hour. 
Every hour this SQL is executed in a stored procedure:delete from requests 
where created < dateadd(-7 day to current_timestamp);

This results in about 90.000 deleted rows.However, after the statement has 
started, i see the number of attachents/statements spike at 150-200 attachments 
for about 20-30 seconds. This results in connection pool full exceptions on the 
web server, and it looks like the database server is not executing other 
statements for that small period of time. 
Please note that the writing of the row in the web request tabel, is done by a 
background thread.
Best regards Thomas Krag-Pedersen
