Subject 回复: Migrate Documents to Another Collection
Date Mon, 06 Feb 2017 03:55:23 GMT
Sorry, I may not be clear enough to express, I describe the following experimental steps:
Step 1: Create two collections
Http://SOLR:8081/solr/admin/collections?action=CREATE&name=c1&numShards=3&replicationFactor=2&maxShardsPerNode=3&collection.configName=myconf
Http://SOLR:8081/solr/admin/collections?action=CREATE&name=c2&numShards=3&replicationFactor=2&maxShardsPerNode=3&collection.configName=myconf


Step 2: import test data, I only imported in c1 inside the collection, the data are as follows
"response":{"numFound":5,"start":0,"maxScore":1.0,"docs":[
      {
        "id":"aa!c10",
        "rowType":"like",
        "title":["vip a red suit0"],
        "description":["Your friend is your needs answered0"],
        "_version_":1558553792955285504},
      {
        "id":"bb!c11",
        "rowType":"like",
        "title":["vip a red suit1"],
        "description":["Your friend is your needs answered1"],
        "_version_":1558553792967868416},
      {
        "id":"aa!c12",
        "rowType":"like",
        "title":["vip a red suit2"],
        "description":["Your friend is your needs answered2"],
        "_version_":1558553792968916992},
      {
        "id":"bb!c13",
        "rowType":"like",
        "title":["vip a red suit3"],
        "description":["Your friend is your needs answered3"],
        "_version_":1558553792969965568},
      {
        "id":"aa!c14",
        "rowType":"like",
        "title":["vip a red suit4"],
        "description":["Your friend is your needs answered4"],
        "_version_":1558553792971014144}]




Step 3: to achieve the merger order, I just want to have id 'aa' at the beginning of the data
mobile past
Http://SOLR:8081/solr/admin/collections?action=MIGRATE&collection=c1&split.key=aa!&target.collection=c2



In the zookeeper C1 state.json has the following parameters:
 "RoutingRules": {"aa!": {
            "RouteRanges": "37100000-3710ffff",
            "TargetCollection": "c2",
            "ExpireAt": "1486353350933"}}



After the implementation of the third step, c1 data has not moved to c2 inside, c2 data is
empty, which is why, is it where I operate incorrect? 

thinks all!

Try with split.key=!
This will migrate all docs.
