This > would simplify the migration in future; > * do not use "*HistoryItem" class for everything, this is not conventional; > * retrieve "dmsVer" from cluster on handshake, this would help to reduce > joining node DataBag size drastically; > * add "isEmpty()" or "long getVersion()" method to metastorage, will be > helpful for components that use it; > * there has to be an ability to read data on client nodes, maybe write as > well, not sure yet; > * implement more optimal in-memory storage for history cache; > * start in-memory metastorage at proper time, current implementation does it > a bit too late. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
