Aerospike和其他NoSQL產(chǎn)品的相比最大的特點是Aerospike可以在大規(guī)模的數(shù)據(jù)下，比如PB級也能取得幾毫秒甚至更低的的延遲和高吞吐量蒸矛。
其他的產(chǎn)品很難同時做到這兩方面，比如Redis的產(chǎn)品特點是它的速度懈凹，它的擴展性比較差泪蔫，當(dāng)擴展到幾TB時蹦狂，就會遇到擴展性的瓶頸磨总。而Cassandra是針對大規(guī)模數(shù)據(jù)的存儲嗦明，他的響應(yīng)速度相對比較慢，這是由于它的產(chǎn)品在事務(wù)處理的構(gòu)架和數(shù)據(jù)存儲結(jié)構(gòu)的缺陷所造成的蚪燕。
Aerospike的另一個特點是它的總擁有成本是隨著數(shù)據(jù)的規(guī)模線性增長的娶牌，而其他的產(chǎn)品總擁有成本往往是非線性增長的，隨著數(shù)據(jù)的增長而急劇增長馆纳，就像下圖那樣诗良。
構(gòu)架特點
Aerospike改變了傳統(tǒng)的緩存層加生產(chǎn)數(shù)據(jù)庫的二層式構(gòu)架，在傳統(tǒng)的生產(chǎn)系統(tǒng)中鲁驶，因為速度的要求鉴裹，往往都會在生產(chǎn)數(shù)據(jù)庫上加一層緩存層，但這使得系統(tǒng)的構(gòu)架變得非常復(fù)雜钥弯，尤其在很多數(shù)據(jù)更新的時候壹罚，保持緩存層和生產(chǎn)數(shù)據(jù)庫的同步就變成了較大的挑戰(zhàn)。
Aerospike是高性能并可持久的寿羞，它可以代替緩存層和生產(chǎn)數(shù)據(jù)庫，而把這兩個部分的功能同時實現(xiàn)出來赂蠢。這樣绪穆，它就可以在處理高性能讀取的同時也可以處理大量數(shù)據(jù)的更新，并實現(xiàn)事務(wù)的強一致性。
