How is MongoDB different from MySQL?
There are differences based on terminology between MongoDB and MySQL. The difference between the way data is represented and stored in both the databases is quite different. MongoDB stores data in form of JSON-like documents and MySQL stores data in form of rows of table as mentioned earlier.
Which should I choose MongoDB or MySQL?
MongoDB is faster than MySQL due to its ability to handle large amounts of unstructured data when it comes to speed. It uses slave replication, master replication to process vast amounts of unstructured data and offers the freedom to use multiple data types that are better than the rigidity of MySQL.
Why MongoDB can scale very efficient compared to MySQL db?
Why is using MongoDB better than using MySQL? Organizations of all sizes are adopting MongoDB, especially as a cloud database, because it enables them to build applications faster, handle highly diverse data types, and manage applications more efficiently at scale.
How does indexing work in MongoDB without index?
Without indexes, MongoDB must perform a collection scan, i.e. scan every document in a collection, to select those documents that match the query statement. If an appropriate index exists for a query, MongoDB can use the index to limit the number of documents it must inspect.
What’s the difference between MongoDB and MySQL?
Similar to most MySQL storage engines, MongoDB also uses B-tree based indexes. There are some other differences in terms of index types or options supported. For example, I believe MongoDB has more geospatial options than a vanilla MySQL install. The MongoDB query optimizer, however, is significantly different.
Which is the best geospatial index for MongoDB?
To support efficient queries of geospatial coordinate data, MongoDB provides two special indexes: 2d indexes that uses planar geometry when returning results and 2dsphere indexes that use spherical geometry to return results. See 2d Index Internals for a high level introduction to geospatial indexes.
What are the main reasons for using MongoDB?
Here are the main reasons for using MongoDB: MongoDB is very flexible and adaptable to real business world situations and requirements. Queries can be made to return certain fields within documents. MongoDB supports field, range-based query, regular expression, etc. for searching the data from the stored data.
