-------------------------------------
Hi Takashi,
# In your first example, you call it Batch request. Sorry I'm very new to solr
so does Batch request mean, more than 1 doc added into 1 request?
#
doc.addField("hasUserAssertions", new HashMap<String, Object>() {{
put("set", false); }}); // this makes sure update only succeeds when
record with specified id exists
you should set it to true to see how many succeeded.
# There's a failOnVersionConflicts=false so theoretically only the invalid id
update will fail.
> exception in updateRequest caused all subsequent update fail

> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: UpdateRequestProcessors
> Affects Versions: 8.5.1
> Reporter: xuanyu huang
> Priority: Minor
>
> Hi there,
> I'm using solrj 8.8.2 for a 8.5.1 solr server. I have a list of records and
> in a for loop I construct an updateRequest to update each record.
> Code looks like this
> {code:java}
> for (Map<String, Object> map : maps) {
> if (map.containsKey("record_uuid")) {
> UpdateRequest updateRequest = new UpdateRequest();
> updateRequest.setAction( UpdateRequest.ACTION.COMMIT, false, false);
> SolrInputDocument doc = new SolrInputDocument();
> if (idx == 3) {
> doc.addField("id", map.get("record_uuid") + "_invalid");
> } else {
> doc.addField("id", map.get("record_uuid"));
> }
> idx++;
> doc.addField("hasUserAssertions", new HashMap<String, Object>() {{
> put("set", true); }});
> // this makes sure update only succeeds when record with specified id
> exists
> doc.addField("_version_", 1);
> logger.debug("Added solr doc for record: " + doc.get("id"));
> updateRequest.add(doc);
> try {
> updateRequest.setParam("failOnVersionConflicts", "false");
> UpdateResponse process = updateRequest.process(solrClient);
> System.out.println("xhk205 process = " + process.toString());
> } catch (Exception e) {
> logger.error("Failed to update solr doc, error message: " +
> e.getMessage(), e);
> }
> }{code}
> There are 5 requests in total and I intentionally set the id in 3rd request
> to be an invalid id so that updateRequet for 3rd record should fail. (This is
> to mimic the situation where the record to be updated no longer exists in
> solr, so I only want those updates with a valid id to succeed, those updates
> with an invalid id should fail/rejected instead of creating a new reocrd in
> solr, so I used __version__=1).
>
> Also I used the syntax to do partial update.
> The variable doc looks like this
> {code:java}
> {
> "id":"2d4b625d-8809-461f-b19b-d0c963e038ed",
> "hasUserAssertions":{"set":true}
> }
> {code}

> {color:#de350b}Since each update is put into its own request, I suppose only
> the 3rd request will fail because there's no record with that id and I've set
> __version__{color} {color:#de350b}to 1. But the reality is, only the first 2
> records were updated and other 3 not.{color}
> {color:#de350b}When I queried in solr admin console after the update, with
> [http://localhost:8983/solr/biocache/select?fq=hasUserAssertions:true&q=*:*]
> there were only 2 records returned instead of 4.{color}
