 It would be great to have some way of subscribing to the results (apart from
 looking at logs/metrics).

+Migration is executed as described above. One subtlety is that (local) deletion on
+source safekeeper might fail, which is not a problem if we are going to
+decomission the node but leaves garbage otherwise. I'd propose in the first version
+1) Don't attempt deletion at all if node status is `offline`.
+2) If it failed, just issue warning.
+And add PUT `/control/v1/safekeepers/:node_id/scrub` endpoint which would find and
+remove garbage timelines for manual use. It will 1) list all timelines on the
+safekeeper 2) compare each one against configuration storage: if timeline
+doesn't exist at all (had been deleted), it can be deleted. Otherwise, it can
+be deleted under generation number if node is not member of current generation.
+
+Automating this is untrivial; we'd need to register all potential missing
+deletions <tenant_id, timeline_id, generation, node_id> in the same transaction
+which switches configurations. Similarly when timeline is fully deleted to
+prevent cplane operation from blocking when some safekeeper is not available

   migration by switching configuration from the joint to the one with (previous) `sk_set` under CAS
   (incrementing generation as always).

-#### API implementation and reconciliation
-
-For timeline creation/deletion we want to preserve the basic assumption that
-unreachable minority (1 sk of 3) doesn't block their completion, but eventually
-we want to finish creation/deletion on nodes which missed it (unless they are
-removed). Similarly for migration; it may and should finish even though excluded
-members missed their exclusion. And of course e.g. such pending exclusion on
-node C after migration ABC -> ABD must not prevent next migration ABD -> ABE. As
-another example, if some node missed timeline creation it clearly must not block
-migration from it. Hence it is natural to have per safekeeper background
-reconciler which retries these ops until they succeed. There are 3 possible
-operation types, and the type is defined by timeline state (membership
-configuration and whether it is deleted) and safekeeper id: we may need to
-create timeline on sk (node added), locally delete it (node excluded, somewhat
-similar to detach) or globally delete it (timeline is deleted).
-
-Next, on storage controller restart in principle these pending operations can be
-figured out by comparing safekeepers state against storcon state. But it seems
-better to me to materialize them in the database; it is not expensive, avoids
-these startup scans which themselves can fail etc and makes it very easy to see
-outstanding work directly at the source of truth -- the db. So we can add table
-`safekeeper_timeline_pending_ops`
-```
-table! {
-    // timeline_id, sk_id is primary key
-    safekeeper_timeline_pending_ops (sk_id, tenant_id, timeline_id) {
-        sk_id -> int8,
-        tenant_id -> Varchar,
-        timeline_id -> Varchar,
-        generation -> Int4,
-        op_type -> Varchar,
-    }
-}
-```
-
-`op_type` can be `include` (seed from peers and ensure generation is up to
-date), `exclude` (remove locally) and `delete`. Field is actually not strictly
-needed as it can be computed from current configuration, but gives more explicit
-observability.
-
-`generation` is necessary there because after op is done reconciler must remove
-it and not remove another row with higher gen which in theory might appear.
-
-Any insert of row should overwrite (remove) all rows with the same sk and
-timeline id but lower `generation` as next op makes previous obsolete. Insertion
-of `op_type` `delete` overwrites all rows.
-
-About `exclude`: rather than adding explicit safekeeper http endpoint, it is
-reasonable to reuse membership switch endpoint: if safekeeper is not member
-of the configuration it locally removes the timeline on the switch. In this case
-404 should also be considered an 'ok' answer by the caller.
-
-So, main loop of per sk reconcile reads `safekeeper_timeline_pending_ops`
-joined with timeline configuration to get current conf (with generation `n`)
-for the safekeeper and does the jobs, infinitely retrying failures:
-1) If node is member (`include`):
-  - Check if timeline exists on it, if not, call pull_timeline on it from 
-     other members
-  - Call switch configuration to the current
-2) If node is not member (`exclude`):
-  - Call switch configuration to the current, 404 is ok.
-3) If timeline is deleted (`delete`), call delete.
-
-In cases 1 and 2 remove `safekeeper_timeline_pending_ops` for the sk and 
-timeline with generation <= `n` if `op_type` is not `delete`.
-In case 3 also remove `safekeeper_timeline_pending_ops` 
-entry + remove `timelines` entry if there is nothing left  in `safekeeper_timeline_pending_ops` for the timeline.
-
-Let's consider in details how APIs can be implemented from this angle.
-
-Timeline creation. It is assumed that cplane retries it until success, so all
-actions must be idempotent. Now, a tricky point here is timeline start LSN. For
-the initial (tenant creation) call cplane doesn't know it. However, setting
-start_lsn on safekeepers during creation is a good thing -- it provides a
-guarantee that walproposer can always find a common point in WAL histories of
-safekeeper and its own, and so absense of it would be a clear sign of
-corruption. The following sequence works:
-1) Create timeline (or observe that it exists) on pageserver,
-   figuring out last_record_lsn in response.
-2) Choose safekeepers and insert (ON CONFLICT DO NOTHING) timeline row into the
-   db. Note that last_record_lsn returned on the previous step is movable as it
-   changes once ingestion starts, insert must not overwrite it (as well as other
-   fields like membership conf). On the contrary, start_lsn used in the next
-   step must be set to the value in the db. cplane_notified_generation can be set
-   to 1 (initial generation) in insert to avoid notifying cplane about initial 
-   conf as cplane will receive it in timeline creation request anyway.
-3) Issue timeline creation calls to at least majority of safekeepers. Using
-   majority here is not necessary but handy because it guarantees that any live
-   majority will have at least one sk with created timeline and so
-   reconciliation task can use pull_timeline shared with migration instead of
-   create timeline special init case. OFC if timeline is already exists call is
-   ignored.
-4) For minority of safekeepers which could have missed creation insert
-   entries to `safekeeper_timeline_pending_ops`. We won't miss this insertion 
-   because response to cplane is sent only after it has happened, and cplane 
-   retries the call until 200 response.
-
-   There is a small question how request handler (timeline creation in this
-   case) would interact with per sk reconciler. As always I prefer to do the
-   simplest possible thing and here it seems to be just waking it up so it
-   re-reads the db for work to do. Passing work in memory is faster, but
-   that shouldn't matter, and path to scan db for work will exist anyway, 
-   simpler to reuse it.
-
-For pg version / wal segment size: while we may persist them in `timelines`
-table, it is not necessary as initial creation at step 3 can take them from
-pageserver or cplane creation call and later pull_timeline will carry them
-around.
-
-Timeline migration.
-1) CAS to the db to create joint conf, and in the same transaction create
-   `safekeeper_timeline_pending_ops` `include` entries to initialize new members
-   as well as deliver this conf to current ones; poke per sk reconcilers to work
-   on it. Also any conf change should also poke cplane notifier task(s).
-2) Once it becomes possible per alg description above, get out of joint conf
-   with another CAS. Task should get wakeups from per sk reconcilers because 
-   conf switch is required for advancement; however retries should be sleep
-   based as well as LSN advancement might be needed, though in happy path 
-   it isn't. To see whether further transition is possible on wakup migration
-   executor polls safekeepers per the algorithm. CAS creating new conf with only
-   new members should again insert entries to `safekeeper_timeline_pending_ops`
-   to switch them there, as well as `exclude` rows to remove timeline from 
-   old members.
-
-Timeline deletion: just set `deleted_at` on the timeline row and insert
-`safekeeper_timeline_pending_ops` entries in the same xact, the rest is done by
-per sk reconcilers.
-
-When node is removed (set to `decomissioned`), `safekeeper_timeline_pending_ops`
-for it must be cleared in the same transaction.
-
-One more task pool should infinitely retry notifying control plane about changed
-safekeeper sets (trying making `cplane_notified_generation` equal `generation`).
-
 #### Dealing with multiple instances of storage_controller

 Operations described above executed concurrently might create some errors but do
 not prevent progress, so while we normally don't want to run multiple instances
 of storage_controller it is fine to have it temporarily, e.g. during redeploy.

-To harden against some controller instance creating some work in
-`safekeeper_timeline_pending_ops` and then disappearing without anyone pickup up
-the job per sk reconcilers apart from explicit wakups should scan for work
-periodically. It is possible to remove that though if all db updates are
-protected with leadership token/term -- then such scans are needed only after
-leadership is acquired.
-
 Any interactions with db update in-memory controller state, e.g. if migration
 request failed because different one is in progress, controller remembers that
 and tries to finish it.
