Key: SOLR-16136
URL: https://issues.apache.org/jira/browse/SOLR-16136
Project: Solr
Issue Type: Wish
Security Level: Public (Default Security Level. Issues are Public)
Components: documentation
Reporter: Adarsh
I am working on a requirment where we are storing stacktraces in apache solr
with datetime. Now if same stacktrace found again on another date then we want
to record to be update with new date appended to the existing date. i have
already marked my date field as multivalued.
Below is the configs :
<updateRequestProcessorChain name="dedupe">
<processor class="solr.processor.SignatureUpdateProcessorFactory">
<bool name="enabled">true</bool>
<str name="signatureField">id</str>
<str name="fields">logger,stacktrace</str>
<bool name="overwriteDupes">true</bool>
<str name="signatureClass">solr.processor.TextProfileSignature</str>
</processor>
<processor class="solr.LogUpdateProcessorFactory" />
<processor class="solr.AtomicUpdateProcessorFactory">
<str name="fields">dateTime</str>
</processor>
<processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>
<requestHandler name="/update" class="solr.UpdateRequestHandler" >
<lst name="defaults">
<str name="update.chain">dedupe</str>
</lst>
</requestHandler>
schema.xml :
<field name="logger" type="string" multiValued="false" indexed="true"
stored="true"/>
<field name="stacktrace" type="text_general" multiValued="false"
indexed="true" stored="true"/>
<field name="dateTime" type="pdates" multiValued="true" indexed="false"
stored="true"/>
code used :
UpdateRequest updateRequest = new UpdateRequest();
updateRequest.setAction(UpdateRequest.ACTION.COMMIT, false, false);
SolrInputDocument myDocumentInstantlycommited = new SolrInputDocument();
Map<String,Object> fieldModifier = new HashMap<>(1);
fieldModifier.put("add",date);
myDocumentInstantlycommited. addField("dateTime", fieldModifier);
myDocumentInstantlycommited.setField("logger", logger);
myDocumentInstantlycommited.setField("stacktrace", stacktrace);
Exception : Can't use SignatureUpdateProcessor with partial update request
containing signature field: logger
