Number of backups of the cache named [ignite sys cache]
hi,
In the 2.7.6 version, start an ignite node through ignite.sh with the
fully default configuration, and then execute the following command:
./control.sh --cache list [.]*
The following output will be found:
[cacheName=ignite-sys-cache, cacheId=-2100569601, grpName=null,
grpId=-2100569601, prim=100, mapped=100, mode=REPLICATED,
atomicity=TRANSACTIONAL, backups=2147483647,
affCls=RendezvousAffinityFunction]
It shows: backups = 2147483647
This is a huge number of backups. Why?

Hi!
It is not the number of backups, I am not sure why it say that value but
you always get that for any replicated cache, quick guess is that it is
set max integer value when you use replicated instead of partitioned cache.

Hi, this is default value for backups for REPLICATED cache mode. This is
Ignite internal system cache and it is stored on each node.

In chinese 这个ignite系统缓存，需要在每个节点上都用到，所以设置成最大值。保证每启动一个节点，系统缓存都有且一致
