Web scraping

In ELK Stack, we have different tools to grab data from remote servers. In traditional Relational Database Management System (RDBMS), it is quite difficult to save these types of data because they are not structured, so either we have to manually clean the data or leave some part of it in order to save it in the table schema. In the case of Elasticsearch, the schemaless behavior gives us the leverage to push any data from any source. It not only holds that data but also provides us with a feature to search and play with it. An example of web scraping using ELK Stack is a Twitter to Elasticsearch connector, which allows us to set up hashtags from Twitter and grab all the tweets that used those hashtags. After grabbing those hashtags, we can search, visualize, and analyze them in Kibana.
