Component.Elasticsearch.2.0.5

Bug fixes

This version fixes a list of issues which can be found on the full changelog.

 

Component.Elasticsearch.2.0.4

Ability to choose communication protocol

Stambia Elasticsearch Component was using Elasticsearch's Transport protocol to communicate with and perform operations on Elasticsearch.

This protocol has been deprecated by Elasticsearch, which currently recommends using the HTTP/REST protocol.

This new Elasticsearch Component version supports using the HTTP/REST protocol for communicating with Elasticsearch.

 

A new attribute has been added to allow choosing which protocol to use.

Default selected protocol is "Transport" for backward compatibility.

Below is some information about the two protocols.

 

Transport protocol

Legacy Elasticsearch protocol which was the default protocol used by Stambia's Elasticsearch Component.

It is supported by Elasticsearch until Elasticsearch version 7.

It is currently deprecated by Elasticsearch, and later versions will not support it.

 

HTTP/REST protocol

HTTP/REST Elasticsearch protocol.

It is the currently recommended protocol client by Elasticsearch.

It is supported from Elasticsearch 5.6 and higher versions.

 

Choosing the protocol in Metadata

In Elasticsearch Metadata, you can select the new protocol on the main server node.

Default value is Transport for backward compatibility.

 

elasticsearch protocol

 

 

Note that "Transport addresses" fields attribute is displayed only when transport protocol is selected.

 

The HTTP Protocol cannot be used with Elasticsearch Version 2.

 

Elasticsearch 2.x legacy support

Elasticsearch 2.x support is now kept as legacy and compatibility purposes, as this version is not supported anymore by Elasticsearch.

Only maintenance and critical fixes will be performed on Elasticsearch 2.x.

 

Change Data Capture (CDC)

Multiple improvements have been performed to homogenize the usage of Change Data Capture (CDC) in the various Components.

Parameters have been homogenized, so that all Templates should now have the same CDC Parameters, with the same support of features.

Multiple fixes have also been performed to correct CDC issues. Refer to the changelog for the exact list of changes.

 

Component.Elasticsearch.2.0.3

Support Xpack Security

Xpack security is now supported by the Component.

You can define a new Xpack security node under your Elasticsearch Metadata.

Define the required properties on it, which may differ depending on your Xpack configuration.

xpack

 

And then use this Xpack node as security by selecting it on security attribute:

 

xpack b security

 

Ability to limit the number of hits returned when performing searches

A new parameter is available on Search Template to limit the number of hits to return.

It is named "ESearch Hit Limit" and defaults to "-1" to retrieve all hits.

 

Bug fixes

This version fixes a list of issues which can be found on the full changelog.

Most notably, it fixes issues with cluster name and Search Guard properties which were ignored.

Do not hesitate to take a look at it to have an idea of what have changed.
