Apache ignite query not working well with index - ignite

Question

I upload the data in ignite 3 cache and total data around 1 million in all 3 caches.while i run query on it i got result in 1s and its generate below query plan
SELECT DISTINCT
A3.VAL2 AS __C0
FROM DPHAF.DPHAF A1
/* DPHAF.DPHAF.__SCAN_ */
/* WHERE (A1.VAL0 = 'dg~')
AND ((A1.PROP6 = '1oh~#has_single_bond')
AND (A1.PROP0 = '4xm~#type'))
*/
INNER JOIN DS_AF.DS_AF S1
/* DS_AF."prop_asc_entity_asc_elem_asc_typ_asc_idx": PROP = A1.PROP6
AND ENTITY = A1.ENTRY
*/
ON 1=1
/* WHERE (A1.PROP6 = S1.PROP)
AND (A1.ENTRY = S1.ENTITY)

INNER JOIN DS_AF.DS_AF S2

ON 1=1

INNER JOIN DPHAF.DPHAF A3
/* DPHAF."entry_asc_idx": ENTRY = S2.ELEM */
ON 1=1

LIMIT 1000
SELECT DISTINCT
__C0 AS VAL2
FROM PUBLIC.__T0
/* DPHAF."merge_scan" */
LIMIT 1000
as you notice there is full cache scan here /* DPHAF.DPHAF.__SCAN_ */
After that when we add index on DPHAF group index it will give us below plan
SELECT
A1.VAL2 AS __C0
FROM DPHAF.DPHAF A1
/* DPHAF."prop0_asc_val0_asc_idx": VAL0 = '7a~'

AND ((A1.VAL5 = '3')
AND ((A1.PROP8 = '1oh~#has_double_bond')
AND (A1.PROP6 = '1oh~#has_single_bond')))))

SELECT

Here you can see we dont have full scan of DPHAF but my query is running for soo long or infinite so am i do anything wrong?
Thanks

It is best if you ask this question at Ignite user forum. It requires debugging to get to the bottom of it.
