Kas t\u00f6\u00f6tate NoSQL-andmehoidla Apache Cassandra'ga?<\/h2>\n

\n23. mail kutsub Odnoklassniki kogenud arendajaid oma Peterburi kontorisse kohtumisele<\/a><\/noindex>, mis on p\u00fchendatud Apache Cassandra kasutamisele. Oluline on vaid teie kogemus Cassandra'ga ja soov seda jagada.
\nRegistreeruge \u00fcritusele<\/a><\/noindex>
\n<\/a><\/noindex>
\nMeie OKn alustasime<\/a><\/noindex> Apache Cassandra kasutamist 2010. aastal foto hindade talletamiseks. Praegu oleme suurimad Apache Cassandra kasutajad Runetis ja \u00fched suurimad Euroopas. Meil on \u00fcle saja erineva klastrite, mida kasutatakse erineva tooteteabe talletamiseks - klassid, vestlused, s\u00f5numid, ja samuti kriitilise infrastruktuuriandmete haldamiseks - loogiliste plokkide kaardistamine suure binaarse andmehoidla juurde - one-cold-storage<\/a><\/noindex>, haldamine sisemise pilve andmetega one-cloud<\/a><\/noindex> jne.<\/p>\n

Kokku on Odnoklassniki<\/a><\/noindex> Cassandra juhtimise all petabaite andmeid tuhandetes nodides. Selle aja jooksul oleme kogunud tohutult kogemusi Cassandra'ga seotud lahenduste haldamisel, arendamisel ja kasutamisel ning oleme isegi t\u00f6\u00f6tanud v\u00e4lja oma enda NewSQL tehingutega andmebaasi<\/a><\/noindex>.<\/p>\n

N\u00fc\u00fcd tahame seda k\u00f5ike teiega jagada - t\u00f5eliste juhtumitega praktikas ja ilma saladusteta; \u00fcritus toimub elava arutelu formaadis osalejate vahel, see t\u00e4hendab, et arutelu h\u00f5ivab suure osa ajast. Eksperdid OK<\/a><\/noindex> on valmis jagama oma ideid ja l\u00e4henemisviise. \u00dcritust viivad l\u00e4bi Oleg Anastasjev<\/a><\/noindex> ja Aleksandr Hristoforov<\/a><\/noindex>.<\/p>\n

Millised teemad on abordis?<\/h2>\n

<\/p>\n

Kasutamine:<\/h3>\n

\nK\u00fclastame t\u00fc\u00fcpilisi node ja klastri konfiguratsioone erinevates tootmispaigaldustes. Arutame, kuidas klastreid laieneda andmemahtude ja koormuse kasvu korral ning kuidas asendada eba\u00f5nnestunud s\u00f5lmed minimaalse m\u00f5ju saavutamiseks klientidele. Jagame oma muresid ja s\u00fcsteemime populaarseid takistusi. Selgitame v\u00e4lja, kuidas klastrit j\u00e4lgida, et varakult m\u00f5ista, kus ja mis t\u00e4pselt ei t\u00f6\u00f6ta. Arutame uute Cassandra versioonide juurutamise probleeme.<\/p>\n

T\u00f5husus:<\/h3>\n

\nP\u00fc\u00fcame m\u00f5ista, millistele m\u00f5\u00f5dikutele peaks t\u00e4helepanu p\u00f6\u00f6rama ja mida v\u00f5iks viimistleda, et paraneda m\u00f5\u00f5dikud. Arutame, kas retreida v\u00f5i mitte ja kui jah, siis kuidas. Tuvastame kitsaskohad Cassandra arhitektuuris ja rakenduses ning uurime m\u00f5ningaid inseneritrikke, et nendest m\u00f6\u00f6da minna. Arutame p\u00f5letava regulaarse repair'i ja compaction'i teemasid ilma j\u00f5udluse halvenemiseta.<\/p>\n

T\u00f5rke taluvus:<\/h3>\n

\nRiistad ei ole igavesed, seet\u00f5ttu juhtub t\u00f5rkeid pidevalt ja ka kolleegi k\u00e4si v\u00f5ib v\u00e4riseda, mist\u00f5ttu arutame ketaste, masinate v\u00f5i andmekeskuste t\u00f5rgete taastamist ning samuti tagasip\u00f6\u00f6rdumist j\u00e4rjepidevasse seisundisse varukoopiatest operaatori vigade korral.<\/p>\n

Registreeruge<\/a><\/noindex> ja r\u00e4\u00e4kige \u00fcritusest s\u00f5pradele ja kolleegidele.
