There are four rules to create the secondary index so that our table will function without any hiccups. These rules are as follows:
Distributing the load by choosing the correct key
Making use of the sparse index
Using the global secondary index for quicker retrieval
Creating a read replica
In the case of a multipartition table, the data as well as the table's associated indexes will be distributed across servers. This distribution of indexes across servers is determined by the value of one of the attributes of the index. Yes, you're correct: it is decided by the hash key value. Unlike the hash key value (compounded with the range key) of a table, indexes keys can be duplicated. In the case of local secondary indexes, this problem will not occur because of the fact that the table's hash key is the same as that of the index, so the index will be distributed similar to the table. Therefore, this practice must...
