Roman Puchkovskiy updated IGNITE-23496:
---------------------------------------
Description: Ignite nodes update leases each 2.5 seconds, in batches. A
batch might contain dozens of thousands (or more) leases. The batch is
serialized to bytes and stored in the Metastorage. Current seriailzation format
is not too compact; for example, having 25000 partitions (and one lease per
partition) in a 3-node cluster, we get approximately 4.7Mb per batch. (was:
Currently, Java Serialization is used to persist data in
DistributionZonesManager. We should not use it (see IGNITE-23135 for
justification).)
