What is the consistency level requirements of our

microservices databases ?

▪ 2 type of "consistency level:

▪ Strict Consistency

When we save data, the data should affect and seen

immediately for every client. Debit or withdraw on bank

account.

▪ Eventual Consistency

When we write any data, it will take some time for

clients reading the data. Youtube video counters.

▪ When we horizontally scaling with the stateful

database services, should split the data which is

calling sharding.

▪ Database sharding is also the way of partitioning

and splitting database servers.

▪ How can we manage data in distributed systems ?
