Been recently playing with a lot of open source tool sets to figure out core solutions for different product ideas that I have. One of the recent technologies I have used is the Elasticsearch tool. Elasticsearch is basically a NoSql based indexing solution that allows one to use Lucene indexes on top of massive data sets especially string based documents. This blog post is just a bunch of notes that I have compiled. What is Elasticsearch? Elasticsearch is a document store with each document stored as an index in a cluster with multiple shards. Sharding is basically a concept of partitioning data based on some metric within the data: Now Elasticsearch exposes an http based request-response to query the individual documents stored in the index. In my case I created a 2 node cluster as shown in the following image: After this step I created an index called imdb_search . Initially wanted to create a Graphing tool to showcase the connections that I had in facebook and the relatio...
