Description

Ignite must provide an option to snapshot only primary copies of partitions.
This will improve:

• snapshot creation time.
• disk usage during snapshot creation.
• space amount to store snapshot.

This will lead to the following disadvantages during restore process:

• rebalance (can be omitted with custom file copy script and cellular affinity)
• index.bin rebuild - performance improved in IGNITE-18271
