Elasticsearch breaking changesedit
This list summarizes the most important breaking changes in Elasticsearch 7.10.2. For the complete list, go to Elasticsearch breaking changes.
Authentication changesedit
API keys now require a name property.
Details
The name property is now required to create or grant an API key.
{
"...": "...",
"api_key": {
"name": "key-1"
}
}
Impact
To avoid errors, specify the name property when creating or granting API keys.
Java changesedit
The MappedFieldType#fielddataBuilder method now accepts a Supplier<SearchLookup> argument.
Details
To support future feature development, the existing
MappedFieldType#fielddataBuilder method now accepts a new
Supplier<SearchLookup> argument.
Impact
If you develop or maintain a mapper plugin, update your implementation of the
MappedFieldType#fielddataBuilder method to accommodate the new signature.
Networking changesedit
The *.tcp.keep_idle and *.tcp.keep_interval settings are now limited to 300 seconds.
Details
The {network,transport,http}.tcp.keep_idle and
{network,transport,http}.tcp.keep_interval settings now have a maximum
value of 300 seconds, equivalent to 5 minutes.
Impact
If specified, ensure the {network,transport,http}.tcp.keep_idle and
{network,transport,http}.tcp.keep_interval settings do not exceed 300
seconds. Setting {network,transport,http}.tcp.keep_idle or
{network,transport,http}.tcp.keep_interval to a value greater than 300
seconds in elasticsearch.yml will result in an error on startup.
Search changesedit
The index.max_docvalue_fields_search setting now limits doc value fields returned by inner_hits or the top_hits aggregation.
Details
The index.max_docvalue_fields_search setting limits the number of doc value
fields retrieved by a search. Previously, this setting applied only to doc value
fields returned by the docvalue_fields parameter in a top-level search. The
setting now also applies to doc value fields returned by an inner_hits section
or top_hits aggregation.
Impact
If you use inner_hits or the top_hits aggregation, ensure
index.max_docvalue_fields_search is configured correctly for your use case.
