Understanding joola.io

What is joola.io? $ npm ins tall joola.io Featu re packed Data An alytics an d Visu alization Fram ework Written in N ode.JS Scalable to deal with h igh volu m es of data an d realtim e qu eries Secu re an d m u lti-ten an t Em bed an d in tegrate data visu alization s in to existin g sites an d apps Open Sou rce

How does it work? Operates an d m an aged via a set of H TTP API en dpoin ts Data pu sh ed u sin g JSON via joola.io's Beacon API Stored in cach in g layer, optim ized for qu ery Qu eries an d Visu alization s provided by Javascript SDK Th at's all in a n u tsh ell!

Pushing Data

Pushing Data is Easy joolaio.beac on.ins ert('c ollec tion-purc has es ', { times tamp: new Date(), Play er: { Us ername: 'A play er', Dev ic e: 'Des k top', Brows er: 'Chrome' }, ip: '127.0.0.1', Vis its : 1, Vis itDuration: 123, Clic k s : 23, Purhc as es : { Amount: 123 Currenc y : 'USD', Status : 'Proc es s ed' } }});

Data Modelling Describe you r data as a JSON docu m en t(s) Docu m en ts are stored in a Collection Sch em a-less, docu m en ts can be of differen t stru ctu re Su pport for all data types Su pport for Stron g-Typed collection s

Push What You'll Need Store on ly data relatin g to An alytics Separate in to logical collection s Describe every m etric with as m an y attribu tes as possible Pass raw data, don 't aggregate Pu sh an array of docu m en ts wh en possible

Caching Layer Based on leadin g providers, su ch as M on goDB, Cassan dra an d m ore Exten d to su pport addition al In sert, u pdate an d delete directly from cach e Execu te qu eries directly on cach in g layer N orm alized access to u n derlyin g cach e via Beacon API

Understanding Queries Describe wh at you wish to display, rath er th an h ow to get it (SQL) Su pport for Realtim e (WebSocket) Join data from m u ltiple collection s Relative tim efram es Advan ced filters Dim en sion an d M etric tran sform ation s M an y aggregation operators, in clu din g U n iqu e Cou n t

Basic Query Describe th e requ ired dim en sion s an d m etric, n ot h ow to qu ery th em joolaio.query .fetc h({ timeframe: 'las t_month', interv al: 'day s ', dimens ions : ['times tamp', 'dev ic e'], metric s : ['v is its ', { k ey : 'av gv is itduration', name: 'Av g.

Calculated Metrics Com pose virtu al, calcu lated m etrics on -th e-fly metric s : [{ k ey :'av gamountperplay er', name: 'Av g.

Query Filters M u ltiple filters - m u tli-level filters - per m etric filters timeframe: 'las t_month', interv al: 'day s ', metric s : [{ k ey : 'play erc ount', depends On: 'Play er.Us ername', aggregation: 'uc ount', filter: [ ['Play er.Brows er', 'eq', 'Chrome']] }], filter: [ ['Play er.Dev ic e', 'eq', 'Des k top'] ]
