[jira] [Updated] (IGNITE-23496) Optimize lease batch serialization

["Roman Puchkovskiy (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IGNITE-23496?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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).)
