resource{color}*{color}
{color:#0000ff}populate XXPolicyRefResource{color}
{color:#0000ff}4. Create the batch of XXPolicyRefResource in DB{color}

{color:#0000ff}populate XXPolicyRefGroup{color}
{color:#0000ff}Insert into DB{color}
{color:#993300}daoMgr.getXXPolicyRefGroup().create(xPolGroup);{color:#800080}*→
{color:#ff0000}1DB write call for each group{color}*{color}{color}
{color:#0000ff}8.For each userNames {color}
{color:#0000ff}Getting XXUser by userName{color}
{color:#993300}XXUser xUser = daoMgr.getXXUser().findByUserName(user);{color}
{color:#800080}*→ {color:#ff0000}1DB Read call for each user{color}*{color}
{color:#0000ff}populate XXPolicyRefUser{color}
{color:#993300}daoMgr.getXXPolicyRefUser().create(xPolUser); {color:#800080}*→

{color:#0000ff}9.For each accessTypes{color}
{color:#0000ff}Getting the XXAccessTypeDef by accessType and
xPolicy.getService() {color}
{color:#800080}XXAccessTypeDef xAccTypeDef =
daoMgr.getXXAccessTypeDef().findByNameAndServiceId(accessType,
xPolicy.getService()); *→ {color:#ff0000}1DB Read call for each
accesType{color}*{color}
{color:#0000ff}populate XXAccessTypeDef{color}
{color:#0000ff}10. Create the batch of xPolAccesses in DB{color}
{color:#993300}daoMgr.getXXPolicyRefAccessType().batchCreate(xPolAccesses);{color}
{color:#800080}*→ {color:#ff0000}1DB Batch Write call{color}*{color}
{color:#0000ff}11.For each conditionTypes{color}
{color:#0000ff}Getting the XXPolicyConditionDef by condition and
xServiceDef.getId(){color}
{color:#993300}XXPolicyConditionDef xPolCondDef =
daoMgr.getXXPolicyConditionDef().findByServiceDefIdAndName(xServiceDef.getId(),
condition){color}; {color:#800080}*→ {color:#ff0000}1DB Read call for each
conditionType{color}*{color}
{color:#0000ff}populate XXPolicyConditionDef{color}
{color:#0000ff}12. Create the batch of xPolConds in DB{color}
{color:#993300}daoMgr.getXXPolicyRefCondition().batchCreate(xPolConds);{color}
{color:#800080}*→ {color:#ff0000}1DB Batch Write call{color}*{color}||
*{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}Note :{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 {color:#993300}{color:#800080}*{color:#ff0000}DB
batch write call instead of 1 DB write call for every
user{color}*{color}{color}{color}
