在分布式系(xi)統(tong)中，節點(dian)(dian)之(zhi)(zhi)(zhi)間(jian)的(de)協(xie)作(zuo)還需要(yao)考慮同步(bu)(bu)的(de)問題。同步(bu)(bu)問題是指(zhi)多(duo)個節點(dian)(dian)之(zhi)(zhi)(zhi)間(jian)需要(yao)協(xie)調執(zhi)行順序(xu)，保(bao)證(zheng)任(ren)務(wu)的(de)正確(que)性和一(yi)致(zhi)性。在分布式系(xi)統(tong)中，由于節點(dian)(dian)之(zhi)(zhi)(zhi)間(jian)的(de)通信延遲和網(wang)絡擁(yong)塞等(deng)原因，節點(dian)(dian)之(zhi)(zhi)(zhi)間(jian)的(de)同步(bu)(bu)問題更加復(fu)雜。例如(ru)，當多(duo)個節點(dian)(dian)同時執(zhi)行相同或不同的(de)任(ren)務(wu)時，可能會出現(xian)任(ren)務(wu)的(de)依賴關系(xi)，導致(zhi)任(ren)務(wu)的(de)執(zhi)行順序(xu)不一(yi)致(zhi)。此時，需要(yao)采用(yong)一(yi)些同步(bu)(bu)技術，如(ru)分布式鎖、分布式事(shi)務(wu)等(deng)，來保(bao)證(zheng)節點(dian)(dian)之(zhi)(zhi)(zhi)間(jian)的(de)協(xie)作(zuo)正確(que)性和一(yi)致(zhi)性。另外，分布式系(xi)統(tong)中的(de)同步(bu)(bu)問題還會影(ying)響系(xi)統(tong)的(de)可用(yong)性和容錯性。湖(hu)北專業(ye)分布式系(xi)統(tong)
