Google Storage for DevelopersStore your data in Googles cloud Google Developer Day 2010

What Is Google Storage?• Store your data in Googles cloud o any format, any amount, any time• You control access to your data o private, shared, or public• Access via Google APIs or 3rd party tools/libraries Google Developer Day 2010

Google Storage Technical DetailsRESTful API • Verbs: GET, PUT, POST, HEAD, DELETE • Resources: identified by URI, like: http://commondatastorage.googleapis.com/bucket/object• Compatible with S3 Buckets• Flat containers (no bucket hierarchy) Google Developer Day 2010

Google Storage : Concepts Basic containers that hold your data, cannot nestBuckets buckets Individual pieces of data : Object data and object metaObjects dataNamespace Single name space across Google storageHierarchy Flat hierarchy any combination of Unicode characters (UTF-8Object Names encoded) less than 1024 bytes in length More restrictive than object names, unique.Bucket Names Conform to DNS settings20 Google Developer Day 2010

Google Storage Use Cases Use Case HTTP VerbCreate a BucketChange ACLs of a BucketUploads an Object PUTChange ACLs of an ObjectList contents of a bucket or ACLsDownload an object or its ACLs GETDelete an ObjectDelete an empty Bucket DELETEUploads an Object using HTML form POSTlists the metadata of an Object HEAD 21 Google Developer Day 2010

Performance and ScalabilityObject types and size• Objects of any type and 100GB+ / Object• Unlimited numbers of objects, 1000s of buckets• Range-get support for data retrievalReplication• All data replicated to multiple US data centers• Leveraging Googles worldwide network for data deliveryConsistency• “Read-your-writes” data consistency Google Developer Day 2010

Security and Privacy FeaturesAuthenticated downloads from a web browser• Sharing with individuals• Group sharing via Google Groups• Sharing with Google Apps domainsPermissions set on Buckets or Objects• READ (an object, or list a bucket’s contents)• WRITE (applicable to buckets, allows upload/delete/etc)• FULL_CONTROL (read/write ACLs on objects or buckets) Google Developer Day 2010

Google Prediction APIGoogles prediction engine in the cloud Google Developer Day 2010

Introducing the Google Prediction API• Googles sophisticated machine learning technology• Available as an on-demand RESTful HTTP web service Google Developer Day 2010

A virtually endless number of applications... Customer Transaction Species Message Diagnostics Sentiment Risk Identification Routing Churn Legal Docket Suspicious Work Roster InappropriatePrediction Classification Activity Assignment ContentRecommend Political Uplift Email Career Products Bias Marketing Filtering Counseling ... and many more ... Google Developer Day 2010

TRAIN The quick brown fox jumped over the "english"The Prediction API lazy dog.finds relevant To err is human, but to really foul thingsfeatures in the "english" up you need a computer.sample data during "spanish" No hay mal que por bien no venga.training. "spanish" La tercera es la vencida.2. PREDICT To be or not to be, that is the ?The Prediction API question.later searches for ? La fe mueve montañas.those featuresduring prediction. Google Developer Day 2010

Introducing the Google Prediction API Google Developer Day 2010

A Prediction API ExampleAutomatically determine application recommendations• Goal: Increase relevancy on the Apps Marketplace via recommendations• Customers: Businesses of various sizes and industries using Google Apps around the world• Data: Sampling of previous installs of applications• Outcome: Predict applications which would be appropriate for a new customer visiting the site Google Developer Day 2010

Using the Prediction APIA simple three step process... Upload your training data to 1. Upload Google Storage Build a model from your data 2. Train 3. Predict Make new predictions Google Developer Day 2010

Step 1: Upload Upload your training data to Google Storage• Training data: outputs and input features• Data format: comma separated value format (CSV), result in first column "SlideRocket","EDUCATION","us","en","10","5" "MailChimp","BUSINESS","us","en","7","0" "MailChimp","STANDARD","se","sv","1","0" "Smartsheet","BUSINESS","us","en","13","4" Upload to Google Storage gsutil cp installs gs://appdata/ Google Developer Day 2010

Step 2: TrainCreate a new model by training on dataTo train a model:POST prediction/v1.1/training?data=appdata%2FinstallsTraining runs asynchronously. To see if it has finished:GET prediction/v1.1/training/appdata%2Finstalls{"data":{ "data":"appdata/installs", "modelinfo":"estimated accuracy: 0.xx"}}} Google Developer Day 2010

Step 3: Predict Apply the trained model to make predictions on new dataPOST prediction/v1.1/query/appdata%2Finstalls/predict{ "data":{ "input": { "mixture" : [ "EDUCATION","us","en","10","0" ]}}}{ data : { "kind" : "prediction#output", "outputLabel":"Manymoon", "outputMulti" :[ {"label":"OffiSync", "score": x.xx} {"label":"Zoho CRM", "score": x.xx} {"label":"MailChimp", "score": x.xx}]}} Google Developer Day 2010

Key Capabilities of BigQuery• Scalable: Billions of rows• Fast: Response in seconds• Simple: Queries in SQL• Web Service o REST o JSON-RPC o Google App Scripts Google Developer Day 2010

Components of BigQuery java python php bq tool client libraries REST, JSON RPC Big Query Service Big Storage52 Google Developer Day 2010

Using BigQueryAnother simple three step process... Upload your raw data to 1. Upload Google Storage Import raw data into 2. Import BigQuery table 3. Query Perform SQL queries on table Google Developer Day 2010

Big Query : Create Data File• Data file is in the CSV format Isabella,F,22067 • Format: CSV [http://tools.ietf.org/html/ Emma,F,17716 rfc4180] • Encoding: UTF-8 Olivia,F,17246 • No header row allowed Sophia,F,16743 • Newlines not supported in quoted strings Ava,F,15730 • Max row size: 64K Emily,F,15204 • Max cell size: 64K • Max file size: 1GB. • Supported cell data formats: ◦ string – UTF-8 encoded string up to 64K of data (as opposed to 64K characters). ◦ integer – IEEE 64-bit signed integers (-264–-264)54 Google Developer Day 2010

Big Query : Upload your Data $./gsutil cp yob2009.txt gs://bucket1/tables/babynames/2009.csvTool compatible with File containing data Destination bucket Google Storage to be uploaded for the data • Data to be uploaded into a single/multiple Big Storage Bucket/s • Use REST endpoints directly or the tool shipped with Google storage 55 Google Developer Day 2010

Big Query : Table Creation $ cat baby_schema [ { "id": "name", "type": "string", "mode": "REQUIRED" }, { "id": "gender", "type": "string", "mode": "REQUIRED" }, { "id": "count", "type": "integer", "mode": "REQUIRED" } ] • Define a schema • id : The string name of the field. Field names are any combination of uppercase and/or lowercase letters (A-Z, a-z), digits (0-9) and underscores. The first character must be a letter. • type : The data type of this field. Supported values: string, integer, float, or boolean • mode : Optional property, specifying whether the cell can be null or not. Supported values: NULLABLE or REQUIRED. Default value is NULLABLE.56 Google Developer Day 2010

Big Query : Table Creation $ bq create bucket1/tables/babynames/tblNames baby_schema { Schema File "kind": "bigquery#table", "name": "bucket1/tables/babynames/tblNames" Table name } Create table in the BigQuery $ bq import bucket1/tables/babynames/tblNames bucket1/tables/babynames/2009.csv Table name { "table": "bucket1/tables/babynames/tblNames", "kind": "bigquery#import_id", Data "import": "d0cf328ed7d9bb46" } Import the data into the table57 Google Developer Day 2010

Big Query : Query the table$ bq query "SELECT name,count FROM [bucket1/tables/babynames/tblNames] WHERE gender = F ORDER BY count DESC LIMIT 5";--------------name COUNT-------- -----Isabella 22067 QueryEmma 17716Olivia 17246Sophia 16743 ResultAva 15730--------------58 Google Developer Day 2010
