Re: Is there a way to restart ignite without data but only table structures.

Re: Error while persisting from Ignite to Hive for a BinaryObject

Hello! Do you have this problem also if you swap Hive with some other DB (H2 comes to mind)? If so, can you create a reproducer project out of those files, post it to e.g. github? Then I will look. My immediate idea is that after you supply aliases Ignite can't find apn_id (or apnId) in your bin

Re: 2.8 release date?

Hello! I think you should be asking on developers list. Ignite is usually released semiannually, so you should expect 2.8 around May. Code freeze will probably happen much more sooner, but getting it out of door took a lot of effort the last time. Maybe it will be easier this time as there are no
