persona one touch fingerprint digital verification takes several minutes, I have more than 50000 fingerprints to verify in Mysql database with java

it is a java code; I need to identify users from their fingerprint; I have over 50,000 records in my table; when a user places their finger on the fingerprint I do a foreach of all users to find the match; with this approach the process takes several minutes and will be annoying for users;

I would like to know if there is another approach I can use to limit this; need your help.

            DPFPTemplate referenceTemplate = DPFPGlobal.getTemplateFactory().createTemplate();
            byte[] templateBuffer;
            DPFPVerificationResult result;
            
            DbMysql dbMysql = new DbMysql();
            ResultSet dataFinger = dbMysql.getFingerData();
            while (dataFinger.next()) {
                String fingerprint = dataFinger.getString("fingerprint");
                String person_id = dataFinger.getString("person_id");
                
                if(fingerprint.equals("")){
                    continue;
                }
                templateBuffer = Base64.getDecoder().decode(fingerprint);
                referenceTemplate.deserialize(templateBuffer);
                result = dpfpVerification.verify(featuresVerification, referenceTemplate);
                
                if (result.isVerified()) {
                    messageStatus = "fingerFound";
                    personId = person_id;
                    
                    break;
                }
                
                System.out.println("#PID" + person_id);
            }

here are the libraries: base64-2.3.7.jar, dpfpenrollment.jar, dpfpverification.jar, msql-connector-java-8.0.30.jar; my SDK is 18;
