Michael Griggs commented on IGNITE-1789:
----------------------------------------
For my use-case, I would prefer to have the option to copy all in-memory
objects and give them new keys that have the snapshot name added in some way,
but remain in the same cache. So for example, Country:GB would get snapshotted
and copied to Country:GB:snapshot1.0, and both Country:GB and
Country:GB:snapshot1.0 would be stored in memory.
> Data Snapshots for Ignite caches
> --------------------------------
>
> Key: IGNITE-1789
> URL: https://issues.apache.org/jira/browse/IGNITE-1789
> Project: Ignite
> Issue Type: New Feature
> Components: cache
> Reporter: Raúl Kripalani
>
> There was a discussion in the dev forum about Data Snapshots in Ignite as a
> way to obtain a consistent and "frozen" view of one or multiple caches in
> order to execute a set of SQL queries, distributed closures, map reduce, etc.
> without having to worry about data slippage (or moving data).
> The discussion is here:
> http://apache-ignite-developers.2346864.n4.nabble.com/Data-Snapshots-in-Ignite-td4183.html
> and we still need to mature the idea, but several users chimed in and
> considered it interesting.
