As a middleware, maybe the backend IoTDB instance is restarted, while the middleware is alive as usual. In this case, the session connection may be broken. So, an auto-retry will be a good experience for users because after restarting the IoTDB instance, they do not need to restart this middleware. >You can use a simple SessionWrapper `org.apache.iotdb.session.pool.SessionPool` to implement it.

jixuan1989 opened a new pull request #959: Move website source code from website repo to this repo and use maven to compile the website URL: https://github.com/apache/incubator-iotdb/pull/959 Hi, Out website source code were on incubator-iotdb-website repo and we have to copy docs from this repo to that repo, and then compile the source codes.. However, there are many things need to be optimized: 1. Documents copy may lead to inconsistency. 2. Users have to install npm and node.js manually. 3. No CI test. 4. It is very very inconvenient because sometimes when you want to change the website, you have to submit a PR here for modifying docs and then submit a PR there for modifying vues... 5. No sitemap generator. So, I move the website source code here as a new module, called "site". Changes in this PR: 1. Upgrade Apache parent version to 23. 2. Fix some url errors in docs. 3. Fix VUE metadata description. 4. Using maven to manage the site module, which allowing install npm and node.js automatically, copy docs, and generate the static HTMLs and sitemap. 5. Change the Jenkinsfile to deploy the website if the master branch is updated. This is an automated message from the Apache Git Service.
