Hi Lucky,


It seems that I was wrong.
You need to increase the value of IgniteSystemProperty#IGNITE_SQL_MERGE_TABLE_MAX_SIZE [1]
The default value is 10 000.


[1] https://ignite.apache.org/releases/2.1.0/javadoc/org/apache/ignite/IgniteSystemProperties.html#IGNITE_SQL_MERGE_TABLE_MAX_SIZE


Thanks.

Hi
    I use jdbc to fetch result from cache.
Class.forName("org.apache.ignite.IgniteJdbcThinDriver");
Connection conn =DriverManager.getConnection("jdbc:ignite:thin://IP");
ResultSet rs = conn.createStatement().executeQuery(sql);


And the sql is like this:
select v.id,v.name,v.seq from (selet a.id as id,b.name as name,c.seq as seq from a inner join b on a.id= b.id left outer join c on a.id=c.id) v left outer join (select did from d where cid in(Ids) group by did having count(did)>=3000) w on v.id = d.did where d.did is null


when 'select did from d where cid in(Ids) group by did having count(did)>=3000' return few records ,this sql is work,but if it return 20,000 records(actually it's often return 10 million records),it got this wrong message:Fetched result set war too large.


And the whole sql is expected 30,000 records.
Any suggestion? Thanks.
Lucky.

Hi Lucky,

You just need to start grid with -DIGNITE_SQL_MERGE_TABLE_MAX_SIZE=30000 JVM
flag.

Thanks,
Slava.
