AutoIndexing is not Working properly [DATACOUCH-550]

[spring-projects-issues]

deniswsrosa opened DATACOUCH-550 and commented

I have enabled autoindexing according to the docs:

@Configuration
public class Config extends AbstractCouchbaseConfiguration {


 @Override
 public String getConnectionString() {
 return "couchbase://127.0.0.1";
 }

 @Override
 public String getUserName() {
 return "Administrator";
 }

 @Override
 public String getPassword() {
 return "password";
 }

 @Override
 public String getBucketName() {
 return "default";
 }


 /**
 * OPTIONAL: In this example we are using annotations to
 */

 @Override
 protected boolean autoIndexCreation() {
 return true;
 }
}

 

And here is my entity:

 

@Document
@Data
@ToString
@CompositeQueryIndex(fields = {"id", "name", "position"})
public class User {

 @Id
 private String id;
 @QueryIndexed
 private String name;
 @QueryIndexed
 private String position;
 private String description;
 private double accountBalance;
}

 

I have tried many variations of the mapping above, and after the application starts no index is created on the target bucket.

AutoIndexing - it works as expected in JUnit tests initialized with @SpringJUnitConfig , but in an spring boot app, when the couchbaseTemplate bean is created, it takes a mappingCouchbaseConverter as the first argument, which in turn takes a couchbaseMappingContext as an argument.  This means that the couchMappingContext is initialized before CouchbaseTemplate.    It is during the initalization of the couchbaseMappingContext that the persistent-entities are processed - including a multicast message to all the applcation listeners.  However, at the time, the auto-indexing application listener has not yet been created by CouchbaseTemplate.  So either there's is something not correct about how the spring-boot application is configured, or the auto-indexing listener needs to be created in couchbaseMappingContext - before the processing of persistent-entities.  (the persistent-entities do get examined when the couchbaseTemplate is created - but they are already cached, so they do not get re-processed.

Note that we disabled auto-index creation by default in MongoDB (DATAMONGO-2477) as automatic index creation creates several subsequent issues and desires to customize the behavior.

*CouchbasePersistentEntityIndexCreator#onApplicationEvent(MappingContextEvent<?, ?>)* seems to never get called even when auto-index is set to true. Using spring-data-couchbase 4.1.2 with Spring Boot.

Hi micopiira - it will only work in JUnit tests initialized with @SpringJUnitConfig - see my note above. 

And although I've added a pull-request to capture the analysis I did earlier, there still needs to be a discussion if this is something we want to support
