Feature: pre/post hook fpr sink job

[nicolas-r]

Hello

in #5, you have implemented pre/post for push & pull jobs.

Do you think this it is possible/feasible to add the same thing for sink jobs ?

This is the workflow I would like to have

• serverA runs a push job (snapshot & send)
• serverB runs a sink job
  • Before receiving the data, it runs the pre hook
  • After receiving data, it runs the post hook script

I think I can do that with a pull job but it means that I have to first run a snapshot job on serverA, wait some time and run a pull job on serverB

Thank you

Hi,

could you describe your use case. How are you going to use this feature?

Hi

Here is that I would like to do

1. server A run a Push job that
   1.1. Run a pre hook before doing the snapshot that will stop some container stack
   1.2 Take the snapshot
   1.3 Rub a post hook to restart the container stack
   1.4 Send the snap to serverB

2. serverB will run a sink job
   2.1 Wait for the connection from serverA
   2.2 serverA connects to it and start sending the data
   2.3 When the replication is over, start a post hoot script that will run restic (or another software)

I may be wrong in my workflow as I just start working with zrepl

What if instead of the whole 2, you'll use post hook on server A like:

- name: "jobA"
  type: "push"
  hooks:
    post:
      path: "/path/to/script/to/run/restic/on/serverB"

so it's like

1.5 When the replication is over, start a post hoot script that will run restic (or another software) on serverB

Will it work for your use case?

This is a possibility you are right.

I'm still evaluating all the possibilities to not use ssh between host or minimize its usage.

If you want, you can close this issue

Let's keep it open for a while. I'll think about it and may be I'll implement hooks on remote side.
