In this code we demonstrate how to build, deploy, connect resilient Java microservices leveraging Istio service mesh. We show how to configure and use circuit breakers, timeouts/retries, rate limits and other advanced resiliency features from Istio without changing the application code.

JPhant: Java Library for PHant Access https://github.com/JPhant/JPhant_Java_Based_Phant_Library *** Features *** Fully Configurable (Public/Private/Delete Keys, Fieldnames, BaseURL, ProxyHost & Port, use GET or POST.) Can Handle multiple simultaneous Phant Data Streams in same program. Can use GET or POST (Using POST will encrypt your PrivateKey and Data in transit.) Can Send/Receive any Character 0 through 127 Support for Paging (Data > 50K.) * Add Data using Get or Post Methods (Configurable.) * Get Data in efficient Format: String[][] aaExample = { {"Field1", "Field2"}, {"Value1", "Value2"}... } * (Or Get Data in Raw Formats - Csv, Json, Jsonp.) * Clear all Data * Get Status in efficient Format (a Stats class encapsulating Cap, PageCount, Remaining, and Used.) * (Or Get Status in Raw Formats - Csv, Json, Jsonp.) * Get Rate Limits (Limit, Remaining, Reset - only valid after addData().) * Convert to/from supported Data Structures (String[][] and ArrayList<ArrayList<String>>.) * Smart CSV Extraction (handles embedded Quotes, Commas, Carriage Returns, and Line Feeds.) * Automatic Retries on HTTPConnection Errors (up to 5 retries.) * Can optionally use a ProxyHost and Port (if you're behind a company Firewall/Proxy Server.) ------------------------------------------------------------------------- I'm going to be very busy for the next few months, and can't develop this further. I hereby put this "as is" in the Public Domain, I hope someone will pick it up and run with it. Here is a quick overview... ------------------------------------------------------------------------- To use: 1) --- Initialize --- 1a) Create a class that implements JPhantConfig and enter the appropriate Keys and Fieldnames. (see JPhant_Config_0.java for an example.) 2) --- Configure --- 2a) Instantiate a JPhant instance, for example... JPhant jPhant0 = new JPhant(new JPhant_Config_0()); 3) --- High Level Commands --- 3a) To Clear All data... jPhant0.clear(); 3b) To Add Data (Fieldnames must exactly match Fields Phant Stream was created with... String[][] aasAddData = new String[][] { {"Field1", "Field2"}, {"Value1", "Value2"} }; jPhant0.addData(aasAddData); 3c) To Get Data... String[][] aasGetData = jPhant0.getData(); for(String[] asRow : aasGetData) { for(String sField : asRow) { System.out.print(sField+", "); } System.out.println(); } 3d) To Get Status... jPhant.Stats jpsStats0 = jPhant0.getStatus(); System.out.println("jpsStats0="+jpsStats0.toString()); 3e) To Get Rate Limits... System.out.println("getXRateLimitLimit()="+jPhant0.getXRateLimitLimit()); System.out.println("getXRateLimitRemaining()="+jPhant0.getXRateLimitRemainin()); System.out.println("getXRateLimitReset()="+jPhant0.getXRateLimitReset()); 4) --- Low Level Raw Data Commands --- 4a) To get Data in Raw Format... System.out.println("getData.CSV="+jPhant0.getData(JPhant.Format.csv).replace("\r", "\\r").replace("\n", "\\n")); System.out.println("getData.JSON="+jPhant0.getData(JPhant.Format.json).replace("\r", "\\r").replace("\n", "\\n")); System.out.println("getData.JSONP="+jPhant0.getData(JPhant.Format.jsonp).replace("\r", "\\r").replace("\n", "\\n")); 4b) To get Status in Raw Format... System.out.println("getStatus.CSV="+jPhant0.getStatus(JPhant.Format.csv).replace("\r", "\\r").replace("\n", "\\n")); System.out.println("getStatus.JSON="+jPhant0.getStatus(JPhant.Format.json).replace("\r", "\\r").replace("\n", "\\n")); System.out.println("getStatus.JSONP="+jPhant0.getStatus(JPhant.Format.jsonp).replace("\r", "\\r").replace("\n", "\\n")); ------------------------------------------------------------------------- Phant returns data in CSV Format like... Field1, Field2 Value1, Value2 ... , ... So the most obvious data structure to use is something like... String[][] aaExample = { {"Field1", "Field2"}, {"Value1", "Value2"}... } And the Collection equivalent... ArrayList<ArrayList<String>> alalData = new ArrayList<ArrayList<String>>(); There are functions to support converting to/from String[][] and ArrayList<ArrayList<String>>. toStringArrayListOfStringArrayLists(String[][]) toStringArrayOfStringArrays(ArrayList<ArrayList<String>>) As a convenience, if these two functions are passed null, they return the first element filled in with Fieldnames. You can handle multiple Phant Streams in one program with separate Phant variables and Configurations, like... JPhant jPhant0 = new JPhant(new JPhant_Config_0()); JPhant jPhant1 = new JPhant(new JPhant_Config_1()); ------------------------------------------------------------------------- What isn't working yet... * It should support the entire UTF-8 Character set, but appears to only work for characters 0 through 127. * Has support for Paging when Data > 50K, but doesn't appear to be working as I expected. * I was going to add support for the Timestamp Field that Phant automatically returns. * AddData() only adds the first row of data passed to it, I was going to add Bulk Updates when multiple rows of data are passed in. ------------------------------------------------------------------------- I hope that when this other project that is pulling me away is over, I can get back to this. In the mean time, feel free to develop it as you see fit.

On-line advertising has been one of the most booming markets since the first on-line ads showed up on the web and now it is a market of hundreds of billions of dollars globally and it still has not lost the steam. Google got $32.2 billion in advertising revenue which is 97% of Google’s total revenue in Q3 2010 - Q2 2011. By far the most lucrative venue for on-line advertising has been search, and much of the effectiveness of search advertising comes from the “AdWords” model of matching search queries to advertisements. For this project, you need to use Java to access an Oracle database and accomplish an on-line ads auction system using various bidding algorithms. 1.1.1 Definition of the AdWords Problem We are going to consider on-line algorithms for solving the AdWords problem, which is defined as follows. Given: • A set of bids by advertisers for search queries; • A click-through rate for each advertiser-query pair; • A budget for each advertiser; • A limit on the number of ads to be displayed with each search query. Respond to each search query with a set of advertisers such that: • The size of the set is no larger than the limit on the number of ads per query. • Each advertiser has bid on the search query. • Each advertiser has enough budget left to pay for the ad if it is clicked upon. The data set consists of three database tables: (primary keys are underlined) Queries(qid:INTEGER, query:VARCHAR(100)) Advertisers(advertiserId:INTEGER, budget:FLOAT, ctc:FLOAT) Keywords(advertiserId:INTEGER, keyword:VARCHAR(100), bid:FLOAT)
