Multiline AggregateItemReader not working as suggested in spring-batch-samples

Asked 2021-Aug-26 at 19:27

I am trying to use the multiline IteamReader following the spring-batch-sample at https://github.com/spring-projects/spring-batch/tree/main/spring-batch-samples#multiline

I am running into compilation error as below -

I am sure there is something related to generics as it looking for class implementing ItemReader but the AggregateItemReader implements ItemReader.

You need to be consistent in what the type of the items is that you want to handle on batch level. According to your step definition it is Trade. By calling chunk(1) on the step builder, you declare that your batch should read items of type Trade with a chunk size of 1 (i.e. one at a time) and pass these on to a writer for items of type Trade. In this case, you need to supply a reader of type ItemReader, a writer of type ItemWriter and optionally a processor of type ItemProcessor.

The problem is that your reader is of type ItemReader>, i.e. it does not yield a Trade for each invocation of its read method but a list of trades.

If you want to use the AggregateItemReader you need to wrap it into a custom reader that works as an adapter and actually returns Trade items and not List.

For example, the custom read method could look like this:

How to publish Spring Batch Metrics to Prometheus Gateway

Asked 2021-Mar-18 at 09:37

I have a spring batch jobs in which I want to push metrics to Prometheus as suggested here

I have a requirement to push only default metrics given by Spring batch via micrometer.There is a easy way in which I dont have to anything and just add following dependency:

Is there any difference in these two approaches?

No, there is no difference. Please note that not all Spring Batch users are Spring Boot users. That's why the sample in Spring Batch's repository shows how to configure a task that pushes metrics to the gateway. Now if you use Spring Boot, you don't have to write that class since an equivalent is configured by Spring Boot automatically.

In second approach how to write it when all we need is default metrics?Pushgatewayurl is fine ,I understood, but if I have dozen of jobs, what to set in jobname and grouping key.?

Spring Batch metrics are tagged by job name, step name, etc, see the Tags column in the Built-in Metrics table. So even if you have multiple jobs, the metrics will be distinct. You can do the filtering on Prometheus side with the corresponding tag.

QUESTION

Spring Batch Reader is reading alternate records

Asked 2020-May-03 at 18:43

I have created a sample spring batch application which is trying to read record from a DB and in writer, it displays those records. However, I could see that only even numbered (alternate) records are printed.

It's not the problem of database as the behavior is consistent with both H2 database or Oracle database.

There are total 100 records in my DB.

With JDBCCursorItemReader, only 50 records are read and that too alternate one as can be seen from log snapshot

With JdbcPagingItemReader, only 5 records are read and that too alternate one as can be seen from log snapshot

My code configurations are given below. Why reader is skipping odd numbered records?

I tried to reproduce your problem, but I couldn't. Maybe it would be great if you could share more code.

Meanwhile I created a simple job to read 100 records from "safety" table a print them to the console. And it is working fine.
