--------------------------------------
Summary: Advanced Search DSL: Improve Select Queries Using
De-duplication During Query Formation
Key: ATLAS-2447
URL: https://issues.apache.org/jira/browse/ATLAS-2447
Project: Atlas
Issue Type: Bug
Components: atlas-core
Affects Versions: trunk
Reporter: Ashutosh Mestry
Assignee: Ashutosh Mestry
Fix For: trunk
In the provided Atlas instance , there are many 1000+ hive_table entities .
Few of them :
db2.table1
db1.table1
db1.table2
db3.table2
DSL query :
{code:java}
typename = hive_table
query = name > "table1"
{code}
listed all the hive_table entities whose name>"table1" ,
With limit 25 per page ,
db3.table2 is in 19th page (467th entity)
db1.table2 is in 21st page (521th entity)
*+Error scenario :+*
DSL query :
{code:java}
typename = hive_db
query = where name > "table1" select db
{code}
limit = 25 , lists only 1 db .
Expected that it would result db3 and db1 along with other db's since "table2"
is greater than "table1" and "table2" is in db3 and db1.
when same query with limit =1000 , lists many results along with db1 and db3.
When limit is 25 , "select db" is done on the returned 25 results of "name >
table1" and selects the db.
Since table2 doesn't appear in the first 25 entities , db3 and db1 didn't
result.
Attaching the screenshots for limit 10000 and limit 25.
