Hello,
I am sorry for the late response.
Yes, I would try to use BINARY.
Thanks,

Thanks for this, this clarifies a lot. Could you only advise which data type
should be used and how to map the field of type which is my class?
Should I use BINARY or this cannot be handled at all? My intuition is that I
should map the my.package.ListingCode to the java.sql.Types.JAVA_OBJECT.
Hello,
Perhaps, I'm missing something but it seems that LONGVARBINARY is not
supported by Apache Ignite.
The full list of available types can be found here:

Thanks,
S.

Hi All,
I tried mapping the fields in number of different combinations based on the
above, but all the time I am failing with the SQLServerException: The
conversion from UNKNOWN to UNKNOWN is unsupported.
The mappings I used in the following structure included:
Thank you for the help!

Yes. In case if you don't want to store it as objects then you can move this
fields to original object:
class a{
Int a;
class b;
}
class b{
int b;
int c;
}
You can change it as next:
class a{
int a,
int b;
int c;
}

Andrei,
As I understand you - the only way to map embedded classes is by using
mapping them as objects and store as BLOBs or other VARBINARY fields in SQL
database?
No way to decompose them into separate fields in the tables?
Eg. ListingCode has:
private String code;
private String
>From web console sources I see next mapping:
{"dbName": "BIT", "dbType": -7, "signed": {"javaType": "Boolean",
"primitiveType": "boolean"}},
{"dbName": "TINYINT", "dbType": -6,
"signed": {"javaType": "Byte", "primitiveType": "byte"},
"unsigned": {"javaType": "Short",
I am not fully sure but according to the specification of java.sql.Types you
can try to use next for Java objects:

Hi Anrei,
My goal is to map the data using CacheJdbcPojoStore and save the data that I
already have in Ignite to SQLServer.
The data model has embedded classes and I don't know how to map them.
Currently I got the following setup, which works fine, but that is only the
subset of data.
Hi,
You have pogo class - your.package.EquityClass wuth next fields:
Long equityID;
private ListingCode firstCode;
private String equityName;
private String equityType;
private String equityClass;
private Set listings;
and you are going to store in into ignite. In
Hi,
I have my Ignite that has complex objects classes with not only generic Java
data types, but also other classes and arrays of classes.
I managed to setup my PojoStore that successfully writes (write-behind) data
to SQL Server table for all generic data types.
I see no examples or
