About us
Warsaw Data Tech Talks (dawniej Warsaw Hadoop User Group) - jeszcze jako WHUG, była jedną z pierwszych w Europie grupą sympatyków technologii Hadoop. Od początku działania grupy(kwiecień 2012), udało nam się z sukcesem zorganizować 36 spotkań i przekonać do dołączenia do grupy 1974 osób :) Mieliśmy przyjemność gościć takie firmy jak Spotify, Criteo, GetinData, dataArtisans, GridGain, TouK oraz wiele innych.
Przez wiele lat Hadoop zyskiwał na świecie popularność, otwierając wielu firmom drzwi do świata Big Data, z upływem lat jednak i rosnącym zainteresowaniem szerok pojętą analizą danych, pojawiło się na rynku wiele innych, użytecznych technologii i metod przetwarzania/analizy danych, które są warte naszej uwagi.
W lutym 2019 roku, jako organizatorzy postanowliśmy zmienić nazwę grupy i nieco rozszczerzyć zakres tematyczny, aby członkowie grupy byli na bieżąco z najnowszymi rozwiązaniami z obszaru Big Data.
Zapraszamy!
