------------------------------------
Hi Eduard,
Thanks for your reply. Following steps were done by us:
a) We loaded data of all database tables like "BinEntry" , "Dataload" ,
"Version" in separate Ignite caches by same name as table name . For ex: Data
of "BinEntry" table was stored in a cache named as "BinEntry" and so on..
b) We did an override of findOne() in spring data repository of "BinEntry"
table . Below is the piece of code for override:
@Override
@Cacheable("BinEntry")
BinEntry findOne(Integer id);
c) After doing the above two steps , on invoking findOne() , the data was
returned from Ignite cache rather than hitting the database.
d) Then we tried invoking another method from spring data repository of
"BinEntry" table . The query executed by this methopd joins another table
"DataLoad " .
This did not work anyways.
@Query("select b from BinEntry b where b.prefix = ( select max (prefix)
from BinEntry binEntry where :prefix like binEntry.prefix " +
"and binEntry.dataLoad in ( select d from DataLoad d join
d.versions dt where dt = :version ) )" +
"and b.dataLoad in ( select d from DataLoad d join d.versions dt
where dt = :version ) )" +
" order by b.id , b.cardType asc")
@Cacheable("BinEntry")
List<BinEntry> findByPrefixAndVersion(@Param("prefix") String prefix,
@Param("version") Version version);
e) We were also not sure what cache name should be used as parameter in
@Cacheable annotation for the second method as the second method would need to
query on both "BinEntry" and "DataLoad" caches.
Please let me know if you need more details. Also please let me know if there
is any existing implementation example of Spring Data + Ignite .
Cheers,
Sury
