java - Custom Security Plugin for Apache Ignite -


i trying use apache ignite in-memory database.
enable security, created own security plugin following link http://smartkey.co.uk/development/securing-an-apache-ignite-cluster/

below implementation details

public class ignitesecurityconfiguration implements pluginconfiguration{         public class<? extends pluginprovider> providerclass(){           return ignitesecurityprovider.class;         }     } public class ignitesecurityprovider implements pluginprovider{     @override     public igniteplugin plugin(){       return new cascacheplugin();     } }       public object createcomponent(plugincontext plugincontext, class aclass){        if(aclass.isassignablefrom(gridsecuriytprocessor.class)){        return new passwordsecurityprocessor();     } else {return null;}    }  public class passwordsecurityprocessor implements gridsecurityprocessor,igniteplugin { @override public securitycontext authenticatenode(clusternode clusternode, securitycredentials securitycredentials){    return new securitycontext(){          public securitysubject subject(){            return new securitysubjext(){              //implement methods            };          }         //other implementation methods     }; }

getting exception when starting ignite using examples/config/example-ignite.xml

caused by: class org.apache.ignite.ignitecheckedexception: failed start spi: tcpdiscoveryspi

any idea on missing? tried passwordsecurityprocessor class implement serializable still did not help.

ignite not provide security capabilities out of box, need implement plugin this. here blog can use example: http://smartkey.co.uk/development/securing-an-apache-ignite-cluster/

to security support need @ commercial products built on top of ignite: https://docs.gridgain.com/docs/security-and-audit

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
