MySQL全文索引、联合索引、like查询、json查询速度哪个快

查询背景

有一个表tmp_test_course大概有10万条记录，然后有个json字段叫outline，存了一对多关系(保存了多个编码，例如jy1577683381775)

我们需要在这10万条数据中检索特定类型的数据，目标总数据量：2931条

SELECT COUNT(*) FROM tmp_test_course WHERE `type`=5 AND del=2 AND is_leaf=1

我们在限定为上面类型的同时，还得包含下面任意一个编码（也就是OR查询）

jy1577683381775
jy1577683380808
jy1577683379178
jy1577683378676
jy1577683377617
jy1577683376672
jy1577683375903
jy1578385720787
jy1499916986208
jy1499917112460
jy1499917093400
jy1499917335579
jy1499917334770
jy1499917333339
jy1499917331557
jy1499917330833
jy1499917329615
jy1499917328496
jy1576922006950
jy1499916993558
jy1499916992308
jy1499917003454
jy1499917002952

下面分别列出4种方式查询outline字段，给出相应的查询时间和扫描行数

一、like查询

耗时248毫秒

SELECT * FROM tmp_test_course WHERE `type`=5 AND del=2 AND is_leaf=1 AND (outline like '%jy1577683381775%'OR outline like '%jy1577683380808%'OR outline like '%jy1577683379178%'OR outline like '%jy1577683378676%'OR outline like '%jy1577683377617%'OR outline like '%jy1577683376672%'OR outline like '%jy1577683375903%'OR outline like '%jy1578385720787%'OR outline like '%jy1499916986208%'OR outline like '%jy1499917112460%'OR outline like '%jy1499917093400%'OR outline like '%jy1499917335579%'OR outline like '%jy1499917334770%'OR outline like '%jy1499917333339%'OR outline like '%jy1499917331557%'OR outline like '%jy1499917330833%'OR outline like '%jy1499917329615%'OR outline like '%jy1499917328496%'OR outline like '%jy1576922006950%'OR outline like '%jy1499916993558%'OR outline like '%jy1499916992308%'OR outline like '%jy1499917003454%'OR outline like '%jy1499917002952%')

EXPLAIN分析结果如下，全表扫描

二、json函数查询

耗时196毫秒，速度稍微快了一点

SELECT * FROM tmp_test_course WHERE `type`=5 AND del=2 AND is_leaf=1AND (JSON_SEARCH(outline, 'one', 'jy1577683381775') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1577683380808') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1577683379178') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1577683378676') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1577683377617') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1577683376672') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1577683375903') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1578385720787') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1499916986208') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1499917112460') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1499917093400') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1499917335579') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1499917334770') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1499917333339') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1499917331557') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1499917330833') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1499917329615') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1499917328496') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1576922006950') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1499916993558') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1499916992308') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1499917003454') IS NOT NULL ORJSON_SEARCH(outline, 'one', 'jy1499917002952') IS NOT NULL  )
