Paval,

Thanks you for response.

I have trying to insert insert data using datastreamer into ignite , Can
you tell me what is the best practice to creating key into ignite.

if i want to create multiple columns of db as key should i use
Ibinaryobject to store as object ? will ignite sql engine understand the
indexes if key is in IBinaryObject.

Thanks
Manan Joshi
