Mappings conflicts should not be ignored. If I read the history correctly, this
option was added when a mapping update to an existing field was considered a
conflict, even if the new mapping was exactly the same. Now that mapping updates
are smart enough to detect conflicting options, we don't need an option to
ignore conflicts.
As a follow up to #10870, this removes support for
index templates on disk. It also removes a missed
place still allowing disk based mappings.

* Removed the docs for `index.compound_format` and `index.compound_on_flush` - these are expert settings which should probably be removed (see https://github.com/elastic/elasticsearch/issues/10778)
* Removed the docs for `index.index_concurrency` - another expert setting
* Labelled the segments verbose output as experimental
* Marked the `compression`, `precision_threshold` and `rehash` options as experimental in the cardinality and percentile aggs
* Improved the experimental text on `significant_terms`, `execution_hint` in the terms agg, and `terminate_after` param on count and search
* Removed the experimental flag on the `geobounds` agg
* Marked the settings in the `merge` and `store` modules as experimental, rather than the modules themselves
Closes#10782
This option defaults to false, because it is also important to upgrade
the "merely old" segments since many Lucene improvements happen within
minor releases.
But you can pass true to do the minimal work necessary to upgrade to
the next major Elasticsearch release.
The HTTP GET upgrade request now also breaks out how many bytes of
ancient segments need upgrading.

Deleting a type from an index is inherently dangerous because
the type can be recreated with new mappings which may conflict
with existing segments still using the old mappings. This
removes the ability to delete a type (similar to how deleting
fields within a type is not allowed, for the same reason).

I've been attempting to programatically verify that adding index templates via the `{path.conf}/templates/` directory works fine although I was never able to validate this via an API call to the `/_template/`. It seems that these templates do not appear in that API call, which I discovered in the following mail thread:
http://elasticsearch-users.115913.n3.nabble.com/Loading-of-index-settings-template-from-file-in-config-templates-td4024923.html#d1366317284000-912
My question is why wouldn't the `/_template/*` method return these templates? This tends to complicate things for those that want to perform automated tests to verify that they are in fact being recognized and used by Elasticsearch.
This commit adds the current total number of translog operations to the recovery reporting API. We also expose the recovered / total percentage:
```
"translog": {
"recovered": 536,
"total": 986,
"percent": "54.3%",
"total_time": "2ms",
"total_time_in_millis": 2
},
```
Closes#9368Closes#10042
To support the `_recovery` API, the recovery process keeps track of current progress in a class called RecoveryState. This class currently have some issues, mostly around concurrency (see #6644 ). This PR cleans it up as well as other issues around it:
- Make the Index subsection API cleaner:
- remove redundant information - all calculation is done based on the underlying file map
- clearer definition of what is what: total files, vs reused files (local files that match the source) vs recovered files (copied over). % based progress is reported based on recovered files only.
- cleaned up json response to match other API (sadly this breaks the structure). We now properly report human values for dates and other units.
- Add more robust unit testing
- Detail flag was passed along as state (it's now a ToXContent param)
- State lookup during reporting is now always done via the IndexShard , no more fall backs to many other classes.
- Cleanup APIs around time and move the little computations to the state class as opposed to doing them out of the API
I also improved error messages out of the REST testing infra for things I run into.

Add ShadowEngine
This has been very trappy. Rather than continue to allow buggy behavior
of having upgrade/optimize requests sidestep the single shard per node
limits optimize is supposed to be subject to, this removes
the ability to run the upgrade/optimize async.
closes#9638
Issue #9566 raises the point that setting the number of shards on a closed index can lead to this index not beeing able to open again. This change in documentation is ment to warn the user about this issue.
We now have a very useful annotation to mark features or parameters as
experimental. Let's use it! This commit replaces some custom text warnings with
this annotation and adds this annotation to some existing features/parameters:
- inner_hits (unreleased yet)
- terminate_after (released in 1.4)
- per-bucket doc count errors in the terms agg (released in 1.4)
I also tagged with this annotation settings which should either be not needed
(like the ability to evict entries from the filter cache based on time) or that
are too deep into the way that Elasticsearch works like the Directory
implementation or merge settings.
Close#9563
The `full` option and `FlushType.NEW_WRITER` only exists to allow
realtime changes to two settings (`index.codec` and `index.concurrency`).
Those settings are very expert and don't really need to be updateable
in realtime.
This adds a new boolean (index.merge.scheduler.auto_throttle) dynamic
setting, default true (matching Lucene), to adaptively set the IO rate
limit for merges over time.
This is more flexible than the previous fixed rate throttling because
it responds depending on the incoming merge rate, so search-heavy
applications that are not doing much indexing will see merges heavily
throttled while indexing-heavy cases will lighten the throttle so
merges can keep up within incoming indexing.
The fixed rate throttling is still available as a fallback if things
go horribly wrong.
Closes#9243Closes#9133
additional element per segment.
This commit adds a verbose flag to the _segments api. Currently the
only additional information returned when set to true is the full
ram tree from lucene for each segment.
make the "es090" postings format read-only, just to support old segments. There is a test version that subclasses it with write-capability for testing.
Closes#8571
Fixes a bug where alias creation would allow `null` for index name, which thereby
applied the alias to _all_ indices. This patch makes the validator throw an
exception if the index is null.
```bash
POST /_aliases
{
"actions": [
{
"add": {
"alias": "empty-alias",
"index": null
}
}
]
}
```
```json
{
"error": "ActionRequestValidationException[Validation Failed: 1: Alias action [add]: [index] may not be null;]",
"status": 400
}
```
The reason this bug wasn't caught by the existing tests is because
the old test for nullness only validated against a cluster which had
zero indices. The null index is translated into "_all", and since
there are no indices, this fails because the index doesn't exist.
So the test passes.
However, as soon as you add an index, "_all" resolves and you get the
situation described in the original bug report: null index is
accepted by the alias, resolves to "_all" and gets applied to everything.
The REST tests, otoh, explicitly tested this bug as a real feature and therefore
passed. The REST tests were modified to change this behavior.
Fixes#7863
This commit adds the ability to enable / disable relocations
on an entire cluster or on individual indices for either:
* `primaries` - only primaries can rebalance
* `replica` - only replicas can rebalance
* `all` - everything can rebalance (default)
* `none` - all rebalances are disabled
similar to the allocation enable / disable functionality.
Relates to #7288
This commit does the following:
* Add the new API at the rest layer, being backed by the optimize API
with upgrade flag, and segments api to find upgrade status.
* Add `upgrade` flag to optimize API, and deprecate `force` flag (will
remove in master)
* Add test for both synchronous and async upgrade
closes#7884closes#7922
Returns information about settings, aliases, warmers, and mappings. Basically returns the IndexMetadata. This new endpoint replaces the /{index}/_alias|_aliases|_mapping|_mappings|_settings|_warmer|_warmers and /_alias|_aliases|_mapping|_mappings|_settings|_warmer|_warmers endpoints whilst maintaining the same response formats. The only exception to this is on the /_alias|_aliases|_warmer|_warmers endpoint which will now return a section for 'aliases' or 'warmers' even if no aliases or warmers exist. This backwards compatibility change is documented in the reference docs.
Closes#4069
