Given the amount of data for two tables, A and b,a and B,When a is less than B, use Existsselect * from A whereexists(SELECT * from B where a.id=b.id) is the implementation of exists, which is equivalent to the outer loop, each time the internal table is queried? for inch A for inch B if j.id = = I.id then ....Conversely, if a is greater than B, then use Inselect * from A where ID in (select ID from B) This is logically similar to for inch B for inch A if j.id = = I.id

The answer is no.
In one situation today, the concurrency of 10 users was very low at first, only tps150, and then suddenly increased to 3800. this may be because the cache is used... for example, cached is very large and has been growing...
The request is cached in Linux because no parameterization is performed, and the TPS remains high.
It may also be that the service is dead, but there is a problem with the way to determine whether the tra

reduced the sorting time to 23 minutes when 206 EC2 nodes were used. This means that Spark is three times faster than MapReduce in sorting the same data when one tenth is used to calculate resources!
In addition, without the official PB sorting comparison, we first pushed Spark to the sorting of 1 PB of data (100,000 billion records. The result of this test is that when 190 nodes are used, the workload is completed in less than 4 hours, it also far exceeds the record that Yahoo previously used

According to my test results, Nginx 0.6.31 + PHP 5.2.6 (FastCGI) can withstand more than 30,000 concurrent connections, equivalent to 10 times times Apache in the same environment.In my experience, the server +apache (prefork mode) of 4GB memory typically handles only 3,000 concurrent connections because they will consume more than 3GB of memo
