The best feature of the solution is that it is a NoSQL database. Many tables make a database. When we define a table, we have to define the schema of the table. For NoSQL databases, we don't need to define it. The table accepts any input. Each row will have its own column. We do not have to define the columns in advance. We can add columns to each row and push the data. We can query as much as we want. SQL databases exist to speed up the queries. This advantage is not present in NoSQL databases. We must query databases very fast. To help with the process, the product provides secondary indexes. Secondary indexes are a copy of the table. The table is constructed in such a way that it can be used to support one query. Whenever we query a particular item, if we give the name of the secondary index in the query, the query will be faster. The solution supports around 20 global secondary indexes. We can just create a table without thinking about its format. When our application develops, we will have more and more queries to do. We might realize later that the initial table does not support the query and that we have to change the schema of the table. To do so, we will have to change the structure of the entire table for one query. In DynamoDB, when we encounter a new query, we can just create a new secondary index for that to an existing table. We wouldn’t have to modify the main table. The query will be fast when we query the secondary index, which is a copy of the main table. Through the production process, we don't have to be concerned about modifying the main table.
