Applied (almost) the same rules we use to validate index names
to new alias names. The only rule not applies it "must be lowercase".
We have tests that don't follow that rule and I except there are lots
of examples of camelCase alias names in the wild. We can add that
validation but I'm not sure it is worth it.
Closes#20748
Adds an alias that starts with `#` to the BWC index and validates
that you can read from it and remove it. Starting with `#` isn't
allowed after 5.1.0/6.0.0 so we don't create the alias or check it
after those versions.
This change adds a `field.with.dots` to all 2.4 bwc indicse and above.
It also adds verification code to OldIndexBackwardsCompatibilityIT to
ensure we upgrade the indices cleanly and the field is present.
Closes#19956
Due to the way the nodes where shut down etc. we always flushed
away the translog. This means we never tested upgrades of transaction
logs from older version. This change regenerates all valid bwc indices
and repositories with transaction logs and adds correspondent changes
to the OldIndexBackwardsCompatibilityIT.java
`create_bwc_index.py` has some cruft in it that only works on 2.x or
even before. This commit make the tool functional, yet there might still
be some bwc relevant things missing here.
Closes#19253
Changes:
- no more option to configure eager/lazy loading of the norms (useless now
that orms are disk-based)
- only the `string`, `text` and `keyword` fields support the `norms` setting
- the `norms` setting takes a boolean that decides whether norms should be
stored in the index but old options are still supported to give users time
to upgrade
- setting a `boost` no longer implicitely enables norms (for new indices only,
this is still needed for old indices)
Warmers are now barely useful and will be removed in 3.0. Note that this only
removes the warmer API and query-based warmers. We still have warmers internally
for eg. global ordinals.
Close#15607
* Added BWC indices
* Added snapshot version to Version.java
* Fixed create_bwc_index to use localhost instead of localhost and 127.0.0.1 (problem with ipv4/6 setup)
There are a few tests that currently use the statically generated
backcompat indexes. This change moves them to a shared location, so they
no longer have to build a path based on the package name of the old
index tests.
Multicast has known issues (see #12999 and #12993). This change moves
multicast into a plugin, and deprecates it in the docs. It also allows
for plugging in multiple zen ping implementations.
closes#13019
When index is introduced into the cluster via cluster upgrade, restore or as a dangled index the MetaDataIndexUpgradeService checks if this index can be upgraded to the current version. If upgrade is not possible, the newly upgraded cluster startup and restore process are aborted, the dangled index is imported as a closed index that cannot be open.
Closes#10215
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.
