ElasticSearch 数据迁移方案
ElasticSearch 常用api{

“cluster_name”: “test-elasticsearch”,
“cluster_uuid”: “FM6vTooBTS6cSM9scMEU7g”,

curl --location --request POST 'http://172.21.0.31:9900/business'
--header 'Content-Type: application/json'
--data-raw '{

},

}'
获取索引结构
curl --location --request GET 'http://172.21.0.31:9900/business_bak'删除索引结构
curl --location --request DELETE 'http://172.21.0.31:9900/business/222'
--header 'Content-Type: application/json'
--data-raw '{
"name": "zhangShang",
"age": 20,
"sex": 1
}'
创建索引文档
当不指定id时，es会自动生成id
curl --location --request POST 'http://172.21.0.31:9900/business/business'
--header 'Content-Type: application/json'
--data-raw '{
"name": "zhangShang",
"age": 20,
"sex": 1
}'
更新索引文档
后面跟着id
curl --location --request POST 'http://172.21.0.31:9900/business/business/AX9jJKe7bgbIdsKXBSG4'
--header 'Content-Type: application/json'
--data-raw '{
"name": "te222st",
"age": 20,
"sex": 1
}'
删除索引文档
curl --location --request DELETE 'http://172.21.0.31:9900/business/business/AX9jJKe7bgbIdsKXBSG4'
--header 'Content-Type: application/json'
--data-raw '{
"name": "te222st",
"age": 20,
"sex": 1
}'
分析检索文本
curl --location --request POST 'http://172.21.0.31:9900/business/_analyze'
--header 'Content-Type: application/json'
--data-raw '{
"text": "zhangzw客户123"
}'
获取索引结构信息
curl --location --request GET 'http://172.21.0.31:9900/business'获取索引结构信息mappings
curl --location --request GET 'http://172.21.0.31:9900/business/_mapping?pretty'获取索引结构信息settings
curl --location --request GET 'http://172.21.0.31:9900/business/_settings' --data-raw ''检索索引文档
curl --location --request GET 'http://172.21.0.31:9900/business/_search?explain'
--header 'Content-Type: application/json'
--data-raw '{
"query": {
"bool": {
"should": [
{
"term": {
"def45310-019d-11ec-8372-1f0ef8ecd3d5": "zw3"
}
}
],
"filter": [
{
"term": {
"account": "N00000002411"
}
}
],
"minimum_should_match": 1
}
}
}'
验证索引文档
curl --location --request GET 'http://172.21.0.31:9900/business/_validate/query?explain'
--header 'Content-Type: application/json'
--data-raw '{
"query": {
"bool": {
"should": [
{
"term": {
"def45310-019d-11ec-8372-1f0ef8ecd3d5": "王五"
}
}
],
"filter": [
{
"term": {
"account": "N00000002411"
}
}
],
"minimum_should_match": 1
}
}
}'
关闭索引
curl --location --request POST 'http://172.21.0.31:9900/business/_close'开启索引
curl --location --request POST 'http://172.21.0.31:9900/business/_open'索引迁移
curl --location --request POST 'http://172.21.0.31:9900/_reindex'
--header 'Content-Type: application/json'
--data-raw '{
"source": {
"index": "business"
},
"dest": {
"index": "business_bak"
}
}'
更新索引结构settings
只能对未设置过的字段进行更新，已存在的字段不能更新，只能重建索引
curl --location --request PUT 'http://172.21.0.31:9900/business/_settings'
--header 'Content-Type: application/json'
--data-raw '{
"analysis.analyzer.default.tokenizer": "1_25_tokenizer_grams",
"analysis.analyzer.default.filter": [
"unique",
"limit_filter"
],
"analysis.tokenizer.1_25_tokenizer_grams.type": "ngram",
"analysis.tokenizer.1_25_tokenizer_grams.min_gram": 1,
"analysis.tokenizer.1_25_tokenizer_grams.max_gram": 25,
"analysis.filter.limit_filter.type": "limit",
"analysis.filter.limit_filter.max_token_count": 500
}'
更新索引结构mappings
和更新索引结构settings用法相同
查看elasticsearch版本信息curl --location --request GET 'http://172.21.0.31:9900'查看elasticsearch所有数据量
curl --location --request GET 'http://172.21.0.31:9900/_count'查看elasticsearch某索引数据量
curl --location --request GET 'http://172.21.0.31:9900/business/_count'查看elasticsearch统计信息
curl --location --request GET 'http://172.21.0.31:9900/_cat/indices?v'异步索引迁移
curl --location --request POST 'http://172.21.0.31:9900/_reindex?wait_for_completion=false'
--header 'Content-Type: application/json'
--data-raw '{
"source": {
"index": "customer"
},
"dest": {
"index": "customer_bak"
}
}'
查看异步任务
curl --location --request GET 'http://172.21.0.31:9900/_tasks'取消异步任务
curl --location --request POST 'http://172.21.0.31:9900/_tasks/OfyS4qUGTW2OuA2BL5fYgQ:36133906/_cancel'查看指定索引的统计信息
curl --location --request GET 'http://172.21.0.31:9900/_cat/indices?v&index=customer_bak'
