------------------------------------
Hello [~roman_khachatryan] ,
Thank you for your quick reply.
I am using Vertica.
Since I prefer not to add more logic to the application and WAL in DB, 2PC
[aren't supported by
Vertica|https://www.vertica.com/docs/9.3.x/HTML/Content/Authoring/ConceptsGuide/Other/Transactions.htm?zoom_highlight=two%20phase%20commit]
, the 3rd option seems to be the way to go.
Are there any examples about WAL in Flink state that you know of where I can
look at?
Thanks!
