Re: write behind question
Hello,
I think you need to use Ignite Cache.load Cache().
See the article: https://apacheignite.readme.io/docs/data-loading

Hello,
Oh, I incorrectly understood you.
You can look at Write-Through[1]. This means that every path to the cache
will be written to the vault (synchronously).
In addition, you can perform SQL directly on Ignite[2].

2. https://apacheignite.readme.io/docs/sql-queries
