我正在使用以下处理器，但是我想将其应用于所有字段.因此，我需要在字段"中添加所有字段，还是有其他方法可以做到这一点.

I am using below processor, but I want to apply it on all fields. So will I need to add all fields in 'field' or is there any other way to do it.

"description": "my pipeline that remvoves empty string and null strings", "processors": [ { "remove": { "field": "my_field", "ignore_missing": true, "if": "ctx.my_field == \"null\" || ctx.my_field == \"\"" } } }

推荐答案

删除处理器不允许您使用通配符 * 来检查所有字段.相反，您可以选择 script 处理器并以通用方式自己执行:

The remove processor doesn't allow you to use wildcard * for checking all fields. Instead you can pick the script processor and do it yourself in a generic way:

{ "script": { "source": """ // find all fields that contain an empty string or null def remove = ctx.keySet().stream() .filter(field -> ctx[field] == "null" || ctx[field] == "") .collect(Collectors.toList()); // remove them in one go for (field in remove) { ctx.remove(field); } """ } }
