Re: Ignite NPE when try to loadCache from persistent mysql database

[Saikat Maitra <sa...@gmail.com>]

Hi

Can you please share if valid cache name can be passed in the loadCache
method like below?

https://github.com/apache/ignite/blob/56975c266e7019f307bb9da42333a6db4e47365e/examples/src/main/java/org/apache/ignite/examples/datagrid/store/jdbc/CacheJdbcStoreExample.java#L108

Regards,
Saikat
