主题: Re: Migrate Documents to Another Collection
I do not understand the problem. The http command you've shown is
simply creating a collection. What does that have to do with migrating
from c1 to c2? In fact, it is recreating c1. Assuming you haven't
redefined the <uniqueKey>, then the router field defaults to "id". So
this is just recreating a plain-vanilla collection. If you already
have a "c1" collection, I expect the above would simply fail.
There's nothing indicating you tried to move docs from C1 to C2 as the
title of this e-mail indicates. There's no magic here, Solr
collections are completely independent of one another. If you want
docs to be moved, _you_ have to move them.
Best,
Erick

回复： Migrate Documents to Another Collection
Posted by alias <52...@qq.com>.
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.
