canal-adapter版本：1.1.5
Elasticsearch版本：7.14

查询语句：

阿里云RDS数据库表

日记：

Elasticsearch查询索引ec_account

映射:

PUT ec_account
{
“settings”: {
“number_of_shards”: 1,
“number_of_replicas”: 1
},
“mappings”: {
“properties”: {
“id”: {
“type”: “long”
},
“username”: {
“type”: “text”
},
“phone”: {
“type”: “long”
},
“email”: {

“first_nickname_char”: {
“type”: “keyword”
},
“gender”: {
“type”: “keyword”
},
“nickname”: {
“type”: “text”
},
“status”: {
“type”: “keyword”
},
“update_time”: {
“type”: “long”,
“index”: false
},
“create_time”: {
“type”: “long”,
“index”: false
},
“delete_time”: {

}
}
}

请问各位大佬为什么同步过去是负数？
