       Presto: join 순서를 변경하지 않음. 왼쪽은 결과셋이 큰테이블, 오른쪽은 작은 테이블을 쓰는게 빠르다(Hive는 무관)
       Presto: join keyword없이 join하는 경우(=oracle style) 테이블 나열 순서 중요함
       Presto : group by 에 컬럼명대신 숫자적는게 미미하게 낫다
       Presto: order by 대략 1만건이하일때 사용 권장, Tableue에서 데이터 끌어올때 굳이 order by 할필요없음

• OurSoftwareDependencyProblem . . . . 6 matches
       The rest of this section outlines some considerations when inspecting a package and deciding whether to depend on it.
       Do many other packages depend on this code? Dependency managers can often provide statistics about usage, or you can use a web search to estimate how often others write about using the package. More users should at least mean more people for whom the code works well enough, along with faster detection of new bugs. Widespread usage is also a hedge against the question of continued maintenance: if a widely-used package loses its maintainer, an interested user is likely to step forward.
       Is the code properly licensed? Does it have a license at all? Is the license acceptable for your project or company? A surprising fraction of projects on GitHub have no clear license. Your project or company may impose further restrictions on the allowed licenses of dependencies. For example, Google disallows the use of code licensed under AGPL-like licenses (too onerous) as well as WTFPL-like licenses (too vague).13
       For Code Search, we developed an abstract Regexp class that defined the interface Code Search needed from any regular expression engine. Then we wrote a thin wrapper around PCRE implementing that interface. The indirection made it easy to test alternate libraries, and it kept us from accidentally introducing knowledge of PCRE internals into the rest of the source tree. That in turn ensured that it would be easy to switch to a different dependency if needed.
       Even with these examples and other off-the-shelf options, run-time isolation of suspect code is still too difficult and rarely done. True isolation would require a completely memory-safe language, with no escape hatch into untyped code. That’s challenging not just in entirely unsafe languages like C and C++ but also in languages that provide restricted unsafe operations, like Java when including JNI, or like Go, Rust, and Swift when including their “unsafe” features. Even in a memory-safe language like JavaScript, code often has access to far more than it needs. In November 2018, the latest version of the NPM package event-stream, which provided a functional streaming API for JavaScript events, was discovered to contain obfuscated malicious code that had been added two and a half months earlier. The code, which harvested large Bitcoin wallets from users of the Copay mobile app, was accessing system resources entirely unrelated to processing event streams.18 One of many possible defenses to this kind of problem would be to better restrict what dependencies can access.
