g*****g 发帖数: 34805 | 5 Not surprising to me. MongoDB is more or less a drop-in replacement of MySQL
. Cassandra is desirable where scalability is a major concern. 90% if not 99
% of Java developers don't care scalability that much.

c******o 发帖数: 1277 | 7 Compare to SQL, still way better than any sql, has auto sharding, and auto
shard balancing.
And it is easier to use compare to Cassandra, have more common feature with
SQL servers, full json document search.
Compare to Cassandra, MongoDB is heavier, more feature, more consistency,
less availability, harder to do ops/scaling.
If you do anything similar to SQL, but want scale up/out, Mongodb probably
is better than Cassandra. That is why it called a "drop in replacement for
MySQL"

cassandra要配spark,比mongo用起来要复杂很多。一般应用mongo足够了。
而且我看很多paas都支持mongo,貌似不支持cassandra

Tool support is far inferior to SQL, lacking of join already makes many
things harder. There are pros and cons that should be weighted but many
people probably don't have adequate knowledge to stack up SQL against NoSQL.

w**z 发帖数: 8232 | 12 haven't worked with Mongo for almost 2 years. The last time I used, two big
complains:
1) whole dataset has to be in the memory in order for it to perform well
2) Since it has master, single point of failure.
Any comments on those?

d****i 发帖数: 4809 | 18 这个里面的关于Java技术的market share基本上和我知道的情况差不多,但是对于我来
说,绝对不会去学任何一种除了Java以外的JVM language,任凭你再吹得天花乱坠。要
牢记JVM trap这个古训。有这时间我去学Node和Python,还有plain old PHP都比再陷
入另外一种JVM语言的陷阱要强。 |

同学们,一般这个东西简称是后面那四个字母
而不是前面的那个单词字母
idea比较讨厌一点是启动比较慢
启动之后就好了,然后插件管理比eclipse要好用些
安装插件很少出错,不象eclipse,plugin经常性出问题
