I was trying to use Streaming for reading basic tuple stream. I am using sort by id asc , I am getting following exception
I am using export search handler as per https://cwiki.apache.org/confluence/display/solr/Exporting+Result+Sets null:java.io.IOException: id must have DocValues to use this feature. at org.apache.solr.response.SortingResponseWriter.getFieldWriters(SortingResponseWriter.java:241) at org.apache.solr.response.SortingResponseWriter.write(SortingResponseWriter.java:120) at org.apache.solr.response.QueryResponseWriterUtil.writeQueryResponse(QueryResponseWriterUtil.java:53) at org.apache.solr.servlet.HttpSolrCall.writeResponse(HttpSolrCall.java:742) at org.apache.solr.servlet.HttpSolrCall.call(HttpSolrCall.java:471) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:214) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:179) at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1652) at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:585) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:143) at org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:577) at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:223) at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1127) at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:515) at org.eclipse.jetty.server.session.SessionHandler.doScope( does it make sense to enable docValues for unique field? How expensive is it? if I have existing collection can I update schema and optimize collection to get docvalues enabled for id? -- Thanks
