[Rust] Quickwit 高性能對象存儲搜索引擎
Quickwit:亞秒級延遲的對象存儲搜索引擎
如果用過 ES,會感到非常熟悉,具體包括以下步驟:
第一步:編寫索引配置文件 wiki_index_config.json
(以 wiki 爲例),保存到當前目錄:
{
"default_search_fields": ["body", "title"], // If you do not specify fields in your query, those fields will be used.
"field_mappings": [
{
"name": "body",
"type": "text"
},
{
"name": "title",
"type": "text"
},
{
"name": "url",
"type": "text",
"indexed": false, // Field not indexed, you will not be able to search on this field.
"stored": false // Field not stored.
}
]
}
第二步:創建索引:
$ ./quickwit new --index-uri file:///$(pwd)/wikipedia --index-config-path ./wiki_index_config.json
其中,wikipedia
是空文件夾
第三步:添加一些文檔(需提前下載文檔文件到當前目錄):
./quickwit index --index-uri file:///$(pwd)/wikipedia --input-path wiki-articles-10000.json
文檔看起來是這樣:
$ head -1 wiki-articles-10000.json
{"url":"https://en.wikipedia.org/wiki?curid=48687903","title":"Jeon Hye-jin (actress, born 1988)","body":"\nJeon Hye-jin (actress, born 1988)\n\nJeon Hye-jin (born June 17, 1988) is a South Korean actress.\nPersonal life.\nJeon married his \"Smile, You\" co-star Lee Chun-hee on March 11, 2011. Their daughter, Lee So Yu, was born on July 30, 2011.\n\n"}
第四步:啓動 Server:
$ ./quickwit serve --index-uri file:///$(pwd)/wikipedia
然後就可以進行 Query 了:
$ curl "http://0.0.0.0:8080/api/v1/wikipedia/search?query=barack+AND+obama"
# 指定 field
$ curl "http://0.0.0.0:8080/api/v1/wikipedia/search?query=body:barack+AND+obama"
文件目錄如下:
$ tree . -L 2
.
├── quickwit
├── wiki-articles-10000.json
├── wiki_index_config.json
└── wikipedia
├── 7fc17075-3a78-4071-be53-e7941023c94a
└── quickwit.json
噢,差點忘了,它還同時提供 gRPC 接口,默認 8082 端口;)

debug2:省空間的 Printer
正常打出來是這樣的:
let complex_structure = vec![
vec![Some(1), Some(2), Some(3), None],
vec![Some(2), None],
vec![Some(4), Some(7)],
vec![Some(1), Some(2), Some(3), None],
];
// 單行
let one_line = format!("{:?}", complex_structure);
assert_eq!(one_line, "[[Some(1), Some(2), Some(3), None], [Some(2), None], [Some(4), Some(7)], [Some(1), Some(2), Some(3), None]]");
// 多行
let many_lines = format!("{:#?}", complex_structure);
assert_eq!(many_lines, "[
[
Some(
1,
),
Some(
2,
),
Some(
3,
),
None,
],
[
Some(
2,
),
None,
],
[
Some(
4,
),
Some(
7,
),
],
[
Some(
1,
),
Some(
2,
),
Some(
3,
),
None,
],
]")
使用本模塊轉爲 String 打出來是這樣的:
use debug2::pprint;
let complex_structure = vec![
vec![Some(1), Some(2), Some(3), None],
vec![Some(2), None],
vec![Some(4), Some(7)],
vec![Some(1), Some(2), Some(3), None],
vec![Some(2), None],
vec![Some(4), Some(7)],
vec![Some(1), Some(2), Some(3), None],
vec![Some(2), None],
vec![Some(4), Some(7)],
];
assert_eq!(
pprint(complex_structure),
"\
[
[Some(1), Some(2), Some(3), None],
[Some(2), None],
[Some(4), Some(7)],
[Some(1), Some(2), Some(3), None],
[Some(2), None],
[Some(4), Some(7)],
[Some(1), Some(2), Some(3), None],
[Some(2), None],
[Some(4), Some(7)],
]"
);
看起來舒服多了。
