Avoid regular indices in frozen tier #70141

henningandersen · 2021-03-09T11:43:55Z

The frozen tier will be dedicated for partially cached searchable
snapshots. This PR ensures that we do not allow allocating regular
indices (including fully cached searchable snapshots) to the frozen
tier.

A setting validator can declare settings that the validation depends on, but when updating index settings, we eagerly validate the settings before submitting the cluster state update and here we do not know the existing settings. With this commit, we ensure that the pre-validation works with such validators, letting the validator validate syntax (validate(value)) only. Relates elastic#70141.

Blob cache index not on frozen. When cloning frozen have to specify the tier

+        } else {
+            setting.validateWithoutDependencies(settings);
+        }


This change and the associated change in SecureSettings and tests have been split into #70144

These tests are going to be touched by other work, will wait merging this until that is done.

Note to self to remove AwaitsFix before merge. Those tests are fixed by #70158, which I will integrate here before merging.

Now done.

Old 7.12/7.13 clusters will create the .snapshot-blob-cache index with tier preference including frozen, which causes cluster state updates to fail when upgrading. Disabling bwc until this is in 7.12.

I've just left one small comment, otherwise looking good. I did not review the dependent setting validation logic.

    public static boolean isSearchableSnapshotStore(Settings indexSettings) {
        return SNAPSHOT_DIRECTORY_FACTORY_KEY.equals(INDEX_STORE_TYPE_SETTING.get(indexSettings));
    }

+    public static boolean isPartialSearchableSnapshotIndex(Map<Setting<?>, Object> indexSettings) {
+        return SNAPSHOT_DIRECTORY_FACTORY_KEY.equals(indexSettings.get(INDEX_STORE_TYPE_SETTING))
+            && (boolean) indexSettings.get(SNAPSHOT_PARTIAL_SETTING);


Could this method throw a NPE if indexSettings does not contain SNAPSHOT_PARTIAL_SETTING?

Yes, it could, but the expectation is that the map contains the two settings. I have added assertions to enforce this.

henningandersen · 2021-03-11T06:38:56Z

Thanks for reviewing, @dakrone and @ywelsch , I integrated the settings changes from #70144 so they no longer appear in this PR. This is ready for another round.

This commit converts the index metadata of searchable snapshot indices using the `shared_cache` storage type to: - Remove all the `index.routing.allocation.(include|exclude|require)._tier` settings - Sets `index.routing.allocation.include._tier_preference` to `data_frozen` automatically when the index metadata is read This is in preperation to enforcing that the `_tier_preference` setting is always set to `data_frozen` for shared cache SBIs.
