Subject [jira] [Commented] (SOLR-2765) Shard/Node states
Date Tue, 11 Oct 2011 18:01:13 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2765?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13125232#comment-13125232

Mark Miller commented on SOLR-2765:
-----------------------------------

One thing we probably want to consider are the limitations we might hit as this XML file grows.
EG - at some point, is grabbing a 800k file on every update going to be a lot worse than incremental
updates against zknodes? Are we going to be okay with a max limit of nodes in the low 1000's?
(Zk max file size is 1 MB - is that overridable without hacking a version?). We will likely
add more meta data to each node over time.

Also, should we consider JSON or YAML over XML? Solr has historically used XML for config,
but I don't want that to unduly influence the right choice here. Solr also has JSON support
(which I would like as better default for talking to Solr myself).
