Deep Dive
Mamodheru anodzidziswa 'kunze kwepamhepo' pamabheji makuru e data renhoroondo, obva ashandisa fungidziro 'pamhepo' munguva chaiyo. Skew inomuka kana nzira mbiri idzi dzichibatanidza zvinhu zvakasiyana. Zvinowanzokonzeresa: kodhi kodhi (Python batch basa vs. Java service service) iyo isingabvumirani nemanomano; kudonha kwenguva, uko kudzidziswa kwepamhepo netsaona kunoshandisa ruzivo rwakanga rwusati rwavepo panguva yekufanotaura; uye maficha epamhepo ekare, uko ukoshi hwakaita senge 'maodha muawa yekupedzisira' inochengetwa uye inopera. Iyo modhi inotaridzika zvakanaka pakuongorora pasina Indaneti asi isinganyatsoita zvakanaka nekuti mapindiro aanoona haachaenderane nezvawakadzidzira. Kuona skew kunoda kutema iwo chaiwo maficha akashumirwa pamhepo uye kuenzanisa kugovera kwavo kunopesana neseti yekudzidziswa, uku kuidzivirira ichifarira tsananguro imwechete yakagovaniswa yenzira mbiri.
