Solr - content length error when loading many data

Správa článků

When many data are found and returned by Solr, the request content lenghth limit may be reached and error 400 may occur.

Example of error returned by Solr:

"Expected mime type application/octet-stream but got application/xml. <?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<response>\n<lst name=\"error\"><str name=\"msg\">application/x-www-form-urlencoded content length (3091319 bytes) exceeds upload limit of 2048 KB</str><int name=\"code\">400</int></lst>\n</response>\n

How to solve it:

Direct solution

Increase the limit in your solrconfig.xml file, for example:
<requestDispatcher handleSelect="false" >
<requestParsers enableRemoteStreaming="true" multipartUploadLimitInKB="2048000" formdataUploadLimitInKB="32768"
addHttpRequestToContext="false"/>
<httpCaching never304="true" />
</requestDispatcher>
Restart your Solr instances:
service solr-server restart

Workarounds

if you does not need all the data, set smaller rows limit in the query
use shorter format for the response - use CSV format and retrieve the necessary fields only
