Jack Krupansky created SOLR-5015:
------------------------------------
Summary: shards.info should return the shard ID
Key: SOLR-5015
URL: https://issues.apache.org/jira/browse/SOLR-5015
Project: Solr
Issue Type: Improvement
Components: SolrCloud
Reporter: Jack Krupansky
Currently, the shards.info section of a SolrCloud query response uses "the |
delimited list of equivalent servers" of the available servers for the shard
keys in the response, rather than the shard IDs (names?.)
My first preference would be for the shard IDs to be used for the shards.info
keys, and then the list of servers could be a "servers" key value at the next
level down in the response. But if compatibility is important, continue to use
the server list as the keys for shards.info, and then add "shardID" or
"shardName" as a key at the next level down in the response.
For example, instead of:
{code}
"shards.info":{
"207.237.114.232:8984/solr/collection1/|207.237.114.232:8986/solr/collection1/":{
"numFound":2,
"maxScore":1.0,
"time":224},
"207.237.114.232:8983/solr/collection1/|207.237.114.232:8985/solr/collection1/":{
"numFound":8,
"maxScore":1.0,
"time":898}},
{code}
My first choice would be:
{code}
"shards.info":{
"shard2": {
"servers":
"207.237.114.232:8984/solr/collection1/|207.237.114.232:8986/solr/collection1/",
"numFound":2,
"maxScore":1.0,
"time":224},
"shard1": {
"servers":
"207.237.114.232:8983/solr/collection1/|207.237.114.232:8985/solr/collection1/",
"numFound":8,
"maxScore":1.0,
"time":898}},
{code}
And my second choice would be:
{code}
"shards.info":{
"207.237.114.232:8984/solr/collection1/|207.237.114.232:8986/solr/collection1/":{
"shardName": "shard2",
"numFound":2,
"maxScore":1.0,
"time":224},
"207.237.114.232:8983/solr/collection1/|207.237.114.232:8985/solr/collection1/":{
"shardName": "shard1",
"numFound":8,
"maxScore":1.0,
"time":898}},
{code}
(We don't have shard "name", but I presume that at some point we will. For now,
it would just be the shard ID.)
I suppose the second choice might be better for non-cloud traditional
distributed Solr - where there is no shard ID/name.
