Description:
*{color:#0000ff}Policy Creation Steps in Apache Ranger:{color}*{color:#0000ff}
{color}
{code:java}
1. Get the service by Name:
RangerService service = getServiceByName(policy.getService());→ 1DB Read call
2. Get XXServiceDef by Name
XXServiceDef xServiceDef =
daoMgr.getXXServiceDef().findByName(service.getType()); → 1DB Read call
3. Get the existing XXPolicy by Name
XXPolicy existing =
daoMgr.getXXPolicy().findByNameAndServiceIdAndZoneId(policy.getName(),
service.getId(), zoneId); → 1DB Read call
4. Create a policy
policy = policyService.create(policy, true); → 1DB Write call
5. Get policy by Id
XXPolicy xCreatedPolicy = daoMgr.getXXPolicy().getById(policy.getId()); → 1DB
Read call
6. createObjectDataHistory for the newly created policy
dataHistService.createObjectDataHistory(createdPolicy,
RangerDataHistService.ACTION_CREATE); → 1DB Write call
7. createTrxLog for the newly created policy
bizUtil.createTrxLog(trxLogList); → 1DB Write call
8. Create Policy Label for the newly created policy
createOrMapLabels(xCreatedPolicy, uniquePolicyLabels); → 1DB Write call
9. Create Policy Mapping For Ref Table
policyRefUpdater.createNewPolMappingForRefTable(policy, xCreatedPolicy,
xServiceDef);
1. Getting
roleNames,groupNames,userNames,accessTypes,dataMaskTypes,conditionTypes from
each policy items of the policy
2. Getting resourceNames from the policy
3.For each resource
Getting the XXResourceDef by resource and policy.getId()
XXResourceDef xResDef =
daoMgr.getXXResourceDef().findByNameAndPolicyId(resource, policy.getId()); →
1DB Read call for each resource
populate XXPolicyRefResource
4. Create the batch of XXPolicyRefResource in DB
daoMgr.getXXPolicyRefResource().batchCreate(xPolResources); → 1DB Batch Write
call
5.For each roleNames
Getting XXRole by roleName
XXRole xRole = daoMgr.getXXRole().findByRoleName(role); → 1DB Read call for
each role
populate XXPolicyRefRole
6. Create the batch of XXPolicyRefRole in DB
daoMgr.getXXPolicyRefResource().batchCreate(xPolRoles); → 1DB Batch Write
call
7.For each groupNames
Getting the XXGroup by groupName
XXGroup xGroup = daoMgr.getXXGroup().findByGroupName(context.group.getName());→
1DB Read call for each group
populate XXPolicyRefGroup
Insert into DB
daoMgr.getXXPolicyRefGroup().create(xPolGroup);→ 1DB write call for each group
8.For each userNames
Getting XXUser by userName
XXUser xUser = daoMgr.getXXUser().findByUserName(user); → 1DB Read call for
each user
populate XXPolicyRefUser
daoMgr.getXXPolicyRefUser().create(xPolUser); → 1DB write call for each user
9.For each accessTypes
Getting the XXAccessTypeDef by accessType and xPolicy.getService()
XXAccessTypeDef xAccTypeDef =
daoMgr.getXXAccessTypeDef().findByNameAndServiceId(accessType,
xPolicy.getService()); → 1DB Read call for each accesType
populate XXAccessTypeDef
10. Create the batch of xPolAccesses in DB
daoMgr.getXXPolicyRefAccessType().batchCreate(xPolAccesses); → 1DB Batch Write
call
11.For each conditionTypes
Getting the XXPolicyConditionDef by condition and xServiceDef.getId()
XXPolicyConditionDef xPolCondDef =
daoMgr.getXXPolicyConditionDef().findByServiceDefIdAndName(xServiceDef.getId(),
condition); → 1DB Read call for each conditionType
populate XXPolicyConditionDef
12. Create the batch of xPolConds in DB
daoMgr.getXXPolicyRefCondition().batchCreate(xPolConds); → 1DB Batch Write call
{code}
*{color:#0000ff}Total number of DB calls involved for the below Policy creation
in Apache Ranger:{color}*
1.Policy contains 500 users,5 access Types (permissions),12 resources
(1DB,1Table,10 columns)
||DB Write count||DB Read count||DB Batch Write count||Time taken to create the
policy||
|504|526|3|{color:#ff0000}4~8 seconds{color}|
2.Policy contains 50 roles,5 access Types (permissions),12 resources
(1DB,1Table,10 columns)
||DB Write count||DB Read count||DB Batch Write count||Time taken to create the
policy||
|4|76|4|{color:#ff0000}~1 second{color}|
{color:#ff0000}Recommendation :{color}
When we reduce the number of users added into policy directly -→ Total number
of DB calls will be reduced
We can use {color:#008000}roles or groups {color} into the policy instead of
adding users directly
{color:#ff0000}Proposal :{color}
{color:#ff0000}We can try DB batch write call instead of 1 DB write call for
every user{color}
