Apache Ignite is how to ensure the data's consistency between multiple
server？Especially, in the case of high concurrency.

"Both" means REPLICATED and PARTITIONED.
You can also think of replicated cache as of partitioned configured with
unlimited number of backups.

Same documentation that Christos suggested applies to both, partitioned and
replicated caches. Also, please take a look at the transaction
documentation here:

Have a look at this:

If you use full sync mode for backups, then the client node will wait for write or commit to complete on all participating remote nodes (primary and backup). This is the most restrictive configuration but will guarantee data consistency.
In addition if you use transactions for any grid operations this will also guarantee that data changes will only be committed only if the whole transaction is successful i.e. if an object with an acquired optimistic lock changes then transaction will fail and any changes will be rolled back.

How does Apache Ignite ensure the data between multiple server is consistency
in anytime?
