Hi folks, I use python to index documents to Solr 9.5.0. I prepared a schema.xml and inserted a row into solrconfig.xml: <schemaFactory class="ClassicIndexSchemaFactory"/>
After this, I tried cbor-based and json-based approaches but none of them worked. The number of documents I tried to index in one request was 15000 but the document size is small: 0.5kb. The request what I sent: response = requests.post(" http://localhost:8983/solr/books/update/json?commit=true", , data=json_data, headers={"Content-Type": "application/json"} ) if response.status_code == 200: print("POST request sent successfully!") print("Response Body:", response.text) else: print("Unexpected response status:", response.status_code) Sometimes it runs and return with 200 status code, sometimes it returns with 400. When it returns error the log file says: 2024-03-12 10:22:35.976 ERROR (qtp973843173-43-localhost-84) [c: s: r: x:books t:localhost-84] o.a.s.h.RequestHandlerBase Client exception => org.apache.solr.common.SolrException: This IndexSchema is not mutable. Thanks in advance, Roland
