Resources Data Types. Home Atlas exposes a variety of REST endpoints to work with types, entities, lineage and data discovery. REST interface for data discovery using dsl or full text search. Base class that captures common-attributes for all Atlas types. An instance of a classification; it doesn't have an identity, this object exists only when associated with an entity.

Reference to an object-instance of an Atlas type - like entity. Reference to an object-instance of AtlasEntity type used in relationship attribute values. AtlasRelationshipDef is a TypeDef that defines a relationship.

As with other typeDefs the AtlasRelationshipDef has a name. Once created the RelationshipDef has a guid. The name and the guid are the 2 ways that the RelationshipDef is identified.

RelationshipDefs have 2 ends, each of which specify cardinality, an EntityDef type name and name and optionally whether the end is a container.

RelationshipDefs can have AttributeDefs - though only primitive types are allowed. RelationshipDefs have a relationshipCategory specifying the UML type of relationship required RelationshipDefs also have a PropogateTag - indicating which way tags could flow over the relationships. RelationshipDefs introduce new attributes to the entity instances.

For example EntityDef A might have attributes attr1,attr2,attr3 EntityDef B might have attributes attr4,attr5,attr6 RelationshipDef AtoB might define 2 ends end1: type A, name attr7 end2: type B, name attr8 When an instance of EntityDef A is created, it will have attributes attr1,attr2,attr3,attr7 When an instance of EntityDef B is created, it will have attributes attr4,attr5,attr6,attr8 In this way relationshipDefs can be authored separately from entityDefs and can inject relationship attributes into the entity instances.

The relationshipEndDef represents an end of the relationship. The end of the relationship is defined by a type, an attribute name, cardinality and whether it is the container end of the relationship. Captures details of struct contents. Not instantiated directly, used only via AtlasEntity, AtlasClassification.The implementation of a specific OMRS connector determines which type s of metadata repository it is able to access. Table 2 shows the OMRS Repository Connectors that provide open metadata access to specific types of metadata repositories.

This means that they use connections to define the network address and user credentials necessary to access a specific instance of a metadata repository.

Figure 1 shows some potential patterns for the use of OMRS Connectors to access different types of metadata repositories. The letters above each pattern A, Together the OMRS Connectors provide a flexible way to make calls to many types of metadata repositories. Fixed the text.

Created by Mandy Chesselllast modified on Mar 30, OMRS Cohort Registry Store - providing a common interface to the cohort registry store that saves information about members of a cohort.

This is how metadata queries are federated across open metadata repositories. It uses its configuration to create the appropriate instances of the OMRS connectors.

Local OMRS Repository Connector This connector wraps a "real" repository connector see table 2 and manages events and validation for this connector. It calls directly to Apache Atlas's internal interface for the metadata repository and as such is always deployed in an Apache Atlas Server.

Every Atlas server will have one of these connectors. It then aggregates the results together to form the response to its call.

But if you want to maintain compatibility with the other REST APIs, that is how the ones for guid and name are made, you need to work in another way, because these APIs refer to the cache.

I did this only to mantain the compatibility with the existing code. If you want I could better study the code and propose a global comprehensive review of that code.

If you agree I could start this task. Changes in ServiceFitler. In my opinion and experience the types are loaded once, they are not many and therefore they occupy little memory while, typically, they are read many times; the introduction of the serviceType cache greatly facilitates these readings with respect to using the cache of only names and guid in terms of cycles. Using predicates will also be very elegant but there are more an more cycles that must be done to aggregate the set of entities that make up the serviceType.

For which I strongly advocate a map by serviceType in typeRegistry. Finally, I think we can change the typeRegistry to improve it, if the code works fine.

If for example I use json scripts and curl I have to do all the work from the application client. If for example I use json scripts and curl I have to do all the work from the application client I am afraid such approach would end up with large number of shallow REST API implementations in Atlas - to support constraints of various clients.

If we notice performance issues, we can consider a subsequent update. Let's keep this simple for now - by only adding FilterUtil. I agree absolutely. I don't want to create a complex Rest system to access however the customer wants. I only think that access by service type is much more useful than access by guid foto example because I have on hands soon the types I need.This Doc explains details about configuring Ranger Atlas Plugin along with a few recommendations.

Atlas is a scalable and extensible set of core foundational governance services — enabling enterprises to effectively and efficiently meet their compliance requirements within Hadoop and allows integration with the whole enterprise data ecosystem. If you are unsure about how to do the above then please refer to the following:.

This document assumes that you have successfully performed the above steps. In addition, please ensure that you have done the following:.

Atlas policies, like all ranger policies are specific to a resource. Resource is the primary target of authorization.

Note: As part of 0. More granular level of access control is planned for next release. Use excludes flag in resource definition when it makes simplifies the policy definition. Each policy can have zero or multiple policy items. The Delegate Admin flag at policy item level can be used to delegate the administration responsibility for a policy to users or user-groups specified on that policy item. The policy can specify if access to the policy resource should be audited or not. Audit specification provides for aggregating the audit events such that similar events within a configurable timeframe would be logged as a single audit along with the total count.

This can be particularly useful when audit volume is high. Evaluate Confluence today. Blog Pages. Space shortcuts File lists. Page tree.
