The content column is not indexed, so it might take a long time for the
database to figure out which records need to be changed.
At mysql/mariadb is mvcc (multi version concurrency control) so your
table stays readable (powerdns can create answers) during updates.

If it's 10K records all pointing to the same host, then yes... making
those CNAMEs to a single name (with an A record) will be much quicker
to update than if they were all A records. There are many reasons why
that might be a bad idea though, so be careful :-)

Yes I am using mysql backend to store the records. But if I have 10K records
and I am updating frequently then every time I do a sql update query my table
will be locked and it takes some time to update that many records. So that's
why I'm looking for a better solution.

Are you storing the records in a database? If so, a select and replace would
work

Hello,
I am new to powerdns and trying to set it up based on my requirements. One
issue that I am facing is how to update an IP address for all my records? For
example, if I have 10K records that are pointing to one host/IP address but
that host goes down and I want to update to a new host ip address, do I have to
update all 10K records?
Or is there a better way to set this up? Maybe I can add 'cname' to all these
10K records and that 'cname' could somehow resolve to an IP address so
essentially when I run the 'dig' command the end result would be the new IP
address.
Also is there a powerdns supported plugin that can be written for this to make
updates simpler?
Best,
Chhavi
