+### SlowSql
+
+SlowSql aims to convert LogData to DatabaseSlowStatement. It extracts data
from `parsed` result and save them as DatabaseSlowStatement. SlowSql will not
abort or edit logs, you can use other LAL for further processing.
+We need to set a log tag("isSlowSql") to enable it. If logs sent to OAP does
not have this tag, slowSql processing will be skipped.The example to set the
tag is following:
+``` json
+[{"tags":{"data":[{"key":"isSlowSql","value":"true"}]},"body":{"json":{"json":"{\"time\":\"20220906153959\",\"id\":\"cb92c1a5b-2691e-fb2f-457a-9c72a392d9ed\",\"service\":\"root[root]@[localhost]\",\"statement\":\"select
sleep(2);\",\"layer\":\"MYSQL\",\"query_time\":2000}"}},"service":"root[root]@[localhost]"}]
Review Comment:
Could you format this JSON?
