Re: Paging in Cassandra
Hello everyone,
This is the solution :
@Autowired
CassandraOperations cassandraOperationsInstance;
...
...
Pageable request = CassandraPageRequest.first(1000);
Slice slice = null;
Query query = Query.empty().pageRequest(request);
do {
slice = cassandraOperationsInstance.slice(query, clazz);
if (slice.hasContent()) {
slice.getContent().forEach(s -> {
// treatement ...
});
}
if (slice.hasNext()) {
request = slice.getPageable();
query = query.pageRequest(request);
} else {
break;
}
} while (!slice.getContent().isEmpty());
Best regards.

Re: Paging in Cassandra
Hello,
It sounds like a client/coding issue. People are working with distinct
clients to connect to Cassandra. And it looks like there are not many
'spring-data-cassandra' users around ¯\_(ツ)_/¯.
You could try giving a try there see if you have more luck:

Paging in Cassandra
Hello Eveyone,
I'm facing a problem with CassandraPageRequest and Slice.
In fact, I'm always obtaining the same Slice and I'm not able to get the
next slice (or Page) of data.
I'm based on this example :
Link : https://github.com/spring-projects/spring-data-cassandra/pull/114
Query query =
Query.empty().pageRequest(CassandraPageRequest.first(10));Slice
slice = template.slice(query, User.class);
do {
// consume slice
if (slice.hasNext()) {
slice = template.select(query, slice.nextPageable(), User.class);
} else {break;
}
} while (!slice.getContent().isEmpty());
I appreciate your help.
