>  
> {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}
