Replication concepts

Data replication concepts involving DLM.

Data Lifecycle Manager terminology
Data Lifecycle Manager (DLM) is a UI service that is enabled through DP Platform. From the DLM UI you can create and manage replication and disaster recovery policies and jobs.
Communicating within services in HDP
DLM App interacts with multiple services within HDP to process replication requests.
How Policies Work in Data Lifecycle Manager
In Data Lifecycle Manager, you create policies to establish the rules you want applied to your replication and disaster recovery jobs. The policy rules you set can include which cluster is the source and which is the destination, what data is replicated, what day and time the replication job occurs, the frequency of job execution, and bandwidth restrictions.
Replication policy
You should take into consideration the following items when creating or modifying a replication policy.
