            QUESTION

            Why should I run multiple elasticsearch nodes on a single docker host?
            Asked 2022-Mar-09 at 18:17

            There are a lot of articles online about running an Elasticsearch multi-node cluster using docker-compose, including the official documentation for Elasticsearch 8.0. However, I cannot find a reason why you would set up multiple nodes on the same docker host. Is this the recommended setup for a production environment? Or is it an example of theory in practice?

            You shouldn't consider this a production environment. The guides are examples, often for lab environments, and testing scenarios with the application. I would not consider them production ready, and compose is often not considered a production grade tool since everything it does is to a single docker node, where in production you typically want multiple nodes spread across multiple availability zones.

            It depends on what is the goal of the parent POM? If it's only for the consolidation dependency versions, you can use a version catalog. A version catalog is a list of dependencies, represented as dependency coordinates, that a user can pick from when declaring dependencies in a build script.

            ElasticSearch - calling UpdateByQuery and Update in parallel causes 409 conflicts
            Asked 2021-Dec-19 at 12:15

            Working with large index (100,000 documents), I have a use case that spawns several threads who are trying to update documents in parallel, the source code uses two methods in updating the documents: Update and UpdateByQuery, so some of the threads calls Update and some of them calls UpdateByQuery. For the sake of brevity, each of the threads tries to update the same property for the entire documents.

            Here is a small POC that demonstrate the use case:

            Indexing 100,000 documents of Product type, and spawn 100 tasks so each task calls Update and UpdateByQuery in parallel. both of them uses MatchAll query.

            ANSWER

            Answered 2021-Dec-15 at 12:54

            TL;DR: You can pass conflicts=proceed to the update_by_query API if you want it to continue working even when hitting conflicts.

            More details: The update_by_query page explains:

            When you submit an update by query request, Elasticsearch gets a snapshot of the data stream or index when it begins processing the request and updates matching documents using internal versioning. When the versions match, the document is updated and the version number is incremented. If a document changes between the time that the snapshot is taken and the update operation is processed, it results in a version conflict and the operation fails. You can opt to count version conflicts instead of halting and returning by setting conflicts to proceed.

            So basically, your update and update_by_query are trying to update the same documents, conflicting with each other. Using conflicts=proceed makes that operation say "oh well, I'll just continue to update the other docs".

            Spring Data Elasticsearch Bulk Index/Delete - Millions of Records
            Asked 2021-Sep-29 at 09:43

            I'm using Spring Data Elasticsearch 4.2.5, we have a job that does ETL (extract, transform and load data) to a particular database table. I'm indexing this data using Elasticsearch while the job is running. The data will be in millions of records and more. Currently, I'm doing index on every iteration. I read that, using elasticsearch index on every iteration might take some time. I wanted to use something like bulk-index, but for that I need to add indexQuery object to List. Adding millions of records to list and doing bulk-index may bring memory issues.

            I need to apply similar kind of process for deletion. When records are deleted based on some common ID, I need to delete related elastic documents and this will also be in millions and more.

            Is there anyway to do indexing/deleting very fast for this requirement? Any help is much appreciated and correct me if my understanding is incorrect.

            For adding the documents you could use bulk indexing for example by collecting the documents to index in a list/array or whatever and when a predefined size is reached - like 500 entries - then do a bulk insert of these.

            For deleting there is no bulk operation, but you could collect ids to delete in a list or array again with am maximum size and then use ElasticsearchOperations.idsQuery(List) to create a query for these ids and pass this into the delete(query) method.

            Edit 29.09.2021:

            the idsQuery was just added in the 4.3 branch, it is simplemented like this (https://github.com/spring-projects/spring-data-elasticsearch/blob/main/src/main/java/org/springframework/data/elasticsearch/core/AbstractElasticsearchRestTransportTemplate.java#L193-L200):

            There is no simple way to accomplish your goal. The automatic processing implied for the sequence under [:b :c] is also problematic.

            You can get partway there using the Tupelo Forest library. See the Lightning Talk video from Clojure/Conj 2017.

            I did some additional work in data destructuring that you may find useful building the tupelo.core/destruct macro (see examples here). You could follow a similar outline to build a recursive solution to your specific problem.

            A related project is Meander. I have worked on my own version which is like a generalized version of tupelo.core/destruct. Given data like this

            Vulnerabilities

            Elasticsearch versions before 7.10.0 and 6.8.14 have an information disclosure issue when audit logging and the emit_request_body option is enabled. The Elasticsearch audit log could contain sensitive information such as password hashes or authentication tokens. This could allow an Elasticsearch administrator to view these details.
            Elasticsearch versions before 6.8.13 and 7.9.2 contain a document disclosure flaw when Document or Field Level Security is used. Search queries do not properly preserve security permissions when executing certain complex queries. This could result in the search disclosing the existence of documents the attacker should not be able to view. This could result in an attacker gaining additional insight into potentially sensitive indices.
            A permission issue was found in Elasticsearch versions before 5.6.15 and 6.6.1 when Field Level Security and Document Level Security are disabled and the _aliases, _shrink, or _split endpoints are used . If the elasticsearch.yml file has xpack.security.dls_fls.enabled set to false, certain permission checks are skipped when users perform one of the actions mentioned above, to make existing data available under a new index/alias name. This could result in an attacker gaining additional permissions against a restricted index.
            In Elasticsearch before 7.9.0 and 6.8.12 a field disclosure flaw was found when running a scrolling search with Field Level Security. If a user runs the same query another more privileged user recently ran, the scrolling search can leak fields that should be hidden. This could result in an attacker gaining additional permissions against a restricted index.

            Install elasticsearch
