**why?** `TXT` entries are very special because external-dns use it to "lock" the owner currently, a DNS will be like that: ``` time="2023-12-16T16:50:40Z" level=info msg="Changing record." action=CREATE record=oops-test... ttl=1 type=CNAME zone=ff... time="2023-12-16T16:50:41Z" level=info msg="Changing record." action=CREATE record=edns-cf-oops-test... ttl=1 type=TXT zone=ff.. time="2023-12-16T16:50:41Z" level=info msg="Changing record." action=CREATE record=edns-cf-cname-oops-test... ttl=1 type=TXT zone=ff... ``` most of the time it's ok but in some cases, sh*t happen and external-dns pod can be killed at the wrong time and it can be annoying because if only the `CNAME` record is created, then external-dns can't update or remove it **how** In fact we have to managed two cases: creation & deletion If we create TXT records in a first step during creation and remove TXT in a last step for deletion we can avoid it safely Maybe this could be made also in other providers

Hello @PascalBourdier, Thanks for this interesting PR ! |
I don't know how to add this test case |
@PascalBourdier I think the bigger problem is, that you fix it only in one provider and maybe we should fix it in all at once. |
In fact, it is a first version and you're right we should do it for all providers |

why?
TXT
entries are very special because external-dns use it to "lock" the ownercurrently, a DNS will be like that:
most of the time it's ok but in some cases, sh*t happen and external-dns pod can be killed at the wrong time
and it can be annoying because if only the
CNAME
record is created, then external-dns can't update or remove ithow
In fact we have to managed two cases: creation & deletion
If we create TXT records in a first step during creation and remove TXT in a last step for deletion we can avoid it safely
Maybe this could be made also in other providers
