[jira] [Created] (SOLR-9207) PeerSync recovery failes if number of
updates requested is high
Pushkar Raste created SOLR-9207:
-----------------------------------
Summary: PeerSync recovery failes if number of updates requested is high
Key: SOLR-9207
URL: https://issues.apache.org/jira/browse/SOLR-9207
Project: Solr
Issue Type: Bug
Affects Versions: 6.0, 5.1
Reporter: Pushkar Raste
Priority: Minor
{{PeerSync}} recovery fails if we request more than ~99K updates.
If update solrconfig to retain more {{tlogs}} to leverage https://issues.apache.org/jira/browse/SOLR-6359
During out testing we found out that recovery using {{PeerSync}} fails if we ask for more than ~99K updates, with following error
{code}
WARN PeerSync [RecoveryThread] - PeerSync: core=hold_shard1 url=<shardUrl>
exception talking to <leaderUrl>, failed
org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: Expected mime type application/octet-stream but got application/xml.
<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="error"><str name="msg">application/x-www-form-urlencoded content length (4761994 bytes) exceeds upload limit of 2048 KB</str><in
t name="code">400</int></lst>
</response>
{code}
We arrived at ~99K with following match
* max_version_number = Long.MAX_VALUE = 9223372036854775807
* bytes per version number = 20 (on the wire as POST requestsends version number as string)
* additional bytes for separate ,
* max_versions_in_single_request = 2MB/21 = ~99864
I could think of 2 ways to fix it
1. Ask for about updates in chunks of 90K inside {{PeerSync.requestUpdates()}}
2. Use application/octet-stream encoding
