Migrating JSR 352 ItemReader/ItemWriter "checkpointInfo()" to Spring Batch 5 equivalent

[abhinaswale]

I am in process to migrate JSR 352 batch job to Spring Batch 5 job.
While migrating I could map open() & close() methods from JSR352 to the target state (as equivalents are available in ItemStreamWriter). However, I didn't find a way to migrate **checkpointInfo()** method to Spring Batch. Any pointers on the approach?

import javax.batch.api.chunk.ItemWriter;
import java.util.logging.Logger;
public class CustomWriter implements ItemWriter {
    private static final Logger LOGGER = Logger.getLogger(CustomWriter.class.getCanonicalName());
    @Override
    public void open(Serializable checkpoint) throws Exception { 
        // some logic
        LOGGER.logp(Level.FINE, CustomWriter.class.getSimpleName(), "open()", "I am opening writing");
    }
 @Override
public void close() throws Exception { 
        // some logic
        LOGGER.logp(Level.FINE, CustomWriter.class.getSimpleName(), "close ()", "I am closing down writing");
    }
   @Override
    public void writeItems(List<Object> items) throws Exception { 
        // some logic
        LOGGER.logp(Level.FINE, CustomWriter.class.getSimpleName(), "writeItens()",
                "I am writing this number of lines: " + items.size());
    }
    @Override
    public Serializable checkpointInfo() throws Exception {
        // some logic
        return "No op writer";
    }
}

The equivalent is ItemStream#update. This is where checkpointing happens (ie updating the context with restart data). Have you tried that?
