It sits in a part of the virtual machine where destructive updates are allowed and where garbage collection dares not approach. In this chapter, we will learn about ETS (Erlang Term Storage) and how to use it as a cache mechanism. Warning! Don’t use ETS as a cache prematurely! Log and analyze your application performance and identify which parts are bottlenecks, so you know whether you should cache, and what you should cache. This chapter is merely an example of how ETS is an acronym for Erlang Term Storage.
The actual limit can be slightly higher than the one specified, but never lower. The scalability of ETS tables of type ordered_set with the write_concurrency option is substantially better in Erlang/OTP 22 than earlier releases. In some extreme cases, you can expect more than 100 times better throughput in Erlang/OTP 22 compared to Erlang/OTP 21. The cause of this improvement is a new data structure called the contention adapting search tree (CA tree for short).

A "match specification" (match_spec) is an Erlang term describing a small "program" that tries to match something.It can be used to either control tracing with erlang:trace_pattern/3 or to search for objects in an ETS table with for example ets:select/2. The same oddity applies to all kinds of table iterations; ets:next/1, ets:select/1-3, ets:match/1-3 and friends.

ETS表的基本： ETS 表可以用来高效存储海量的erlang数据，ETS提供大型的键-值查询表， ETS是相当高效的：可以用它存储海量的数据（只要有足够的内存）.最常用的表操作是插入和查找。 ETS表的数据保存在内存里，他们是易失的

In many Erlang applications, ETS is heavily used and is a critical component of their implementation. To benefit from multicores, the Erlang/OTP virtual machine has been adapted to use multiple schedulers which
