Page replacement priority

hello,

When there is insufficient memory, if a page replacement occurs, will 
the data be swapped out of memory first, or will the index also be 
swapped out of memory?

Or are there any optimized algorithms?

Hello,

Data pages have the same priority as index pages. Algorithm can be
configured by DataRegionConfiguration.PageReplacementMode property.
See
https://ignite.apache.org/docs/latest/memory-configuration/replacement-policies
for more information.
