索引恢复优先级
编辑索引恢复优先级
编辑未分配的分片会尽可能按优先级顺序恢复。索引按以下优先级顺序排序：
- 可选的
index.priority设置（值越高优先级越高） - 索引创建日期（日期越新优先级越高）
- 索引名称（按字母顺序，后字母比前字母优先级高）
这意味着，默认情况下，较新的索引将比旧的索引先恢复。
使用每个索引可动态更新的 index.priority 设置来自定义索引的优先级顺序。例如：
resp = client.indices.create(
index="index_1",
)
print(resp)
resp1 = client.indices.create(
index="index_2",
)
print(resp1)
resp2 = client.indices.create(
index="index_3",
settings={
"index.priority": 10
},
)
print(resp2)
resp3 = client.indices.create(
index="index_4",
settings={
"index.priority": 5
},
)
print(resp3)
response = client.indices.create(
index: 'index_1'
)
puts response
response = client.indices.create(
index: 'index_2'
)
puts response
response = client.indices.create(
index: 'index_3',
body: {
settings: {
'index.priority' => 10
}
}
)
puts response
response = client.indices.create(
index: 'index_4',
body: {
settings: {
'index.priority' => 5
}
}
)
puts response
const response = await client.indices.create({
index: "index_1",
});
console.log(response);
const response1 = await client.indices.create({
index: "index_2",
});
console.log(response1);
const response2 = await client.indices.create({
index: "index_3",
settings: {
"index.priority": 10,
},
});
console.log(response2);
const response3 = await client.indices.create({
index: "index_4",
settings: {
"index.priority": 5,
},
});
console.log(response3);
PUT index_1
PUT index_2
PUT index_3
{
"settings": {
"index.priority": 10
}
}
PUT index_4
{
"settings": {
"index.priority": 5
}
}
在上面的例子中
-
index_3将首先恢复，因为它具有最高的index.priority。 -
index_4将紧随其后恢复，因为它具有次高的优先级。 -
index_2将接下来恢复，因为它创建时间较晚。 -
index_1将最后恢复。
此设置接受整数值，并且可以使用更新索引设置 API在活动索引上进行更新
resp = client.indices.put_settings(
index="index_4",
settings={
"index.priority": 1
},
)
print(resp)
response = client.indices.put_settings(
index: 'index_4',
body: {
'index.priority' => 1
}
)
puts response
const response = await client.indices.putSettings({
index: "index_4",
settings: {
"index.priority": 1,
},
});
console.log(response);
PUT index_4/_settings
{
"index.priority": 1
}
