Hi all! My index is dynamically updated. This means, that every day I have new data, and every day I remove unused documents from it. Approximately, I know number of documents, which I'm indexing per day.
Today I had tested a situation. Simple imagine, there is an one collection and two shards with two replicas. I had indexed some data to it. After that I run a query: http://10.112.1.2:8080/solr/collection1/select?q=*%3A*&wt=xml&rows=0&shards.info=true <response> <lst name="responseHeader"> <int name="status">0</int> <int name="QTime">74</int> <lst name="params"> <str name="wt">xml</str> <str name="q">*:*</str> <str name="rows">0</str> <str name="shards.info">true</str> </lst> </lst> <lst name="shards.info"> <lst name="10.112.1.2:8081/solr/collection1/|10.112.1.2:8083/solr/collection1/"> <long name="numFound">58647</long> <float name="maxScore">1.0</float> <long name="time">37</long> </lst> <lst name="10.112.1.2:8080/solr/collection1/|10.112.1.2:8082/solr/collection1/"> <long name="numFound">58876</long> <float name="maxScore">1.0</float> <long name="time">48</long> </lst> <result name="response" numFound="117523" start="0" maxScore="1.0"/> </response> Lets say, at one shiny day, number of documents, which I need to index will doubled. This means, that I will have more docuemnts in shards and this is very bad for me for some reasons. But I found a solution, I had simply add new shard with replica to collection and index some data again: <response> <lst name="responseHeader"> <int name="status">0</int> <int name="QTime">74</int> <lst name="params"> <str name="wt">xml</str> <str name="q">*:*</str> <str name="rows">0</str> <str name="shards.info">true</str> </lst> </lst> <lst name="shards.info"> <lst name="10.112.1.2:8081/solr/collection1/|10.112.1.2:8083/solr/collection1/"> <long name="numFound">98949</long> <float name="maxScore">1.0</float> <long name="time">37</long> </lst> <lst name="10.112.1.2:8080/solr/collection1/|10.112.1.2:8082/solr/collection1/"> <long name="numFound">98898</long> <float name="maxScore">1.0</float> <long name="time">48</long> </lst> <lst name="10.112.1.2:8084/solr/collection1/|10.112.1.2:8085/solr/collection1/"> <long name="numFound">40183</long> <float name="maxScore">1.0</float> <long name="time">68</long> </lst> </lst> <result name="response" numFound="238030" start="0" maxScore="1.0"/> </response> Seems this works, and it suits me, but I don't remember where I'd read, that if I want to increase a number of shards in collection I need to reindex whole data. Please advise me, does my solution correct? Many thanks. -- View this message in context: http://lucene.472066.n3.nabble.com/SolrCloud-Shard-resize-tp4020282.html Sent from the Solr - User mailing list archive at Nabble.com.
