Remove `common` query and `cutoff_frequency` parameter of
`match` and `multi_match` queries. Both have already been
deprecated for the next 7.x version.
Closes: #37096
With the removal of node.max_local_storage_nodes, there is no need anymore to keep the data in
subfolders indexed by a node ordinal. This commit makes it so that ES 8.0 will store data directly in
$DATA_DIR instead of $DATA_DIR/nodes/$nodeOrdinal.
Upon startup, Elasticsearch will check to see if there is data in the old location, and automatically
move it to the new location. This automatic migration only works if $nodeOrdinal is 0, i.e., multiple
node instances have not previously run on the same data path, which required for
node.max_local_storage_nodes to explicitly be configured.
We deprecated these settings awhile ago, in favor of cluster.remote. In
7.x we were gentle and provided automatic upgrade of these settings to
the new settings. Now it is time for them to go. This commit removes the
deprecated search.remote settings.
This setting, which prior to Elasticsearch 5 was enabled by default and caused all kinds of
confusion, has since been disabled by default and is not recommended for production use. The
preferred way going forward is for users to explicitly specify separate data folders for each started
node to ensure that each node is consistently assigned to the same data path.
Relates to #42426
We deprecated `restoreShard` and `snapshotShard` in #42213
This change removes the deprecated methods and their usage and adds
a note in the migration docs.
This commit removes the deprecated migrate tool which was used to
migrate users from the file realm to native realm when the native realm
was first created.
Removed the leniency when encoding remote reindex search requests that
was introduced in 7.x. All index-names are now encoded before being sent
to the remote host.
Follow-up to #40303
This is related to #36652. There are a number of transport settings that
were deprecated and replaced with new versions in 7.x. This commit
removes them from 8.0.
The current java implementation of Fuzziness leaves a lot of room for
initializing it with illegal values that either cause errors later when the
queries reach the shards where they are executed or values that are silently
ignored in favour of defaults. We should instead tighten the java implementation
of the class so that we only accept supported values. Currently those are
numeric values representing the edit distances 0, 1 and 2, optionally also as
float or string, and the "AUTO" fuzziness, which can come in a cusomizable
variant that allows specifying two value that define the positions in a term
where the AUTO option increases the allowed edit distance.
This change removes several redundant ways of object construction and adds input
validation to the remaining ones. Java users should either use one of the
predefined constants or use the static factory methods `fromEdits(int)` or
`fromString(String)` to create instances of the class, while other ctors are
hidden. This allows for instance control, e.g. returning one of the constants
when creating instances from an integer value.
Previously the class would accept any positive integer value and any float
value, while in effect the maximum allowed edit distance was capped at 2 in
practice. These values while throw an error now, as will any other String value
other than "AUTO" that where previously accepted but led to numeric exceptions
when the query was executed.
Removes the deprecated accept_default_password setting.
This setting become redundant when default passwords were removed
from 6.0, but the setting was kept for BWC.
Removes native role store cache settings.
These have been unused since 5.2 but were kept for BWC.
Changed default of compress setting from false to true for blob store
repositories. This aligns the code with existing documentation and also
seems like the better default.
Removes all traces of Zen1 from the code base. Some of these commits will also be backported to
7.0/7.x (#39470) as the cluster.coordination package was making use of some things in
discovery.zen and we want to keep 7.x as close as possible to master.
Blob store compression was all implemented generally, except reading the
setting for it. Moved the setting to BlobStoreRepository to unify this.
Also removed deprecated env setting 'repositories.fs.compress'.
This is a follow up on #39073
The removal of the "nGram" and "edgeNGram" token filter was filed in a new
migrate_8_0/mappings.asciidoc document but it should better be in an
analysis.asciidoc section and file.
In #30209 we deprecated the camel case `nGram` filter name in favour of `ngram` and
did the same for `edgeNGram` and `edge_ngram`. Using these names has been deprecated
since 6.4 and is issuing deprecation warnings since then.
I think we can remove these filters in 8.0. In a backport of this PR I would change what was a
dreprecation warning from 6.4. to an error starting with new indices created in 7.0.
