Hi Ed,
1. Yes, that's possible and you do this in Ignite by configuring several
data regions
<
https://apacheignite.readme.io/docs/memory-configuration#section-data-regions>.
All the caches/tables with hot data will be mapped to data regions that are
given most of the memory resources, while caches/tables with cold data can
reside in data regions with little memory space.
2. Even though Ignite supports key-value APIs and can be used as a
key-value store, it's storage engine is classified as a B-tree-based
storage engine
<
https://www.gridgain.com/docs/latest/developers-guide/memory-centric-storage#memory-architecture>.
Having said that, you can use any APIs to process Ignite records.
3. Yes, that's doable. This page
<
https://www.gridgain.com/docs/latest/developers-guide/configuring-caches/managing-data-distribution>
covers the most straightforward approaches for data distribution management.
4. Ignite doesn't support multi-tenancy out-of-the-box. So, you can build
it in house and plugin into Ignite or use enterprise solutions
<
https://www.gridgain.com/docs/latest/administrators-guide/security/multi-tenancy>
.
5. Yes, you can do that. But it might be expensive to update records that
store tree objects. Probably, you don't even need that as long as Ignite is
a B-tree-based storage engine.
