问题
Recently I am doing some research about the performance of java local caches and, of course, I run into ehcache. As far as can see in the documentation and in the artifacts published in maven repository, it seems that there are two active development lines, version 2 and version 3. Furthermore, spring-boot include both in the super pom.
So, my question is: what is it that for? Do both chase the same objectives? What functionalities include version 3?
Thanks in advance!
回答1:
Version 3 is, as you would expect, the new version. Version 2 is still wildly used and for some time, version 3 was missing some features, including clustering. This is why Spring-Boot embed both.
Right now version 3 is the actively maintained and developed version. It should in fact be faster. It is also type-safe and JSR107 (JCache) compatible.
If this is not your experience, I am highly interested in seeing your benchmark.
