The user wants a 1500+ word article, divided into 6-8 paragraphs, each 150-250 words, about "XtremeData数据库". Title is "XtremeData数据库". They want output only the body, no title. Must be natural, conversational style, no AI jargon. Must meet word count: at least 1500 characters? Actually they say must write 1500 words, cannot be less than 1050 words. Wait they say "字数要求：必须写满1500字，不能少于1050字！". That's contradictory: must be exactly 1500 characters? They say "字数要求：必须写满1500字，不能少于1050字！" meaning must be at least 1500 characters? Or words? They say "必须写满1500字" maybe means words? They also say "不能少于1050字". Actually they want at least 1500 words? But then they say "不能少于1050字". So they want at least 1500 characters? Hard to parse. They also say structure: 6-8 paragraphs, each 150-250 words. If each paragraph is 150-250 words, total would be 900-2000 words. To satisfy both constraints, we can aim for about 1500 words total, maybe 6 paragraphs of ~250 words each = 1500 words. That matches "必须写满1500字". So we need about 1500 words (Chinese characters? They say "字". Usually Chinese count characters, but they talk about words. We'll produce approx 1500 Chinese characters? But they said "字数要求：必须写满1500字，不能少于1050字！". So we need at least 1500 characters (or words) but not less than 1050. We'll produce about 1600-1800 Chinese characters? But they ask for 1500 words, each paragraph 150-250 words. That's contradictory: 150-250 words per paragraph, 6-8 paragraphs => total 900-2000 words. To meet "must be 1500 words", we can aim for 6 paragraphs of 250 words each = 1500 words. That fits. So each paragraph ~250 words, 6 paragraphs => 1500 words. That meets both constraints.
We must not output the title. Just the body.
We need to write in natural, conversational Chinese, no AI jargon. Must avoid certain words: 开头禁用 certain phrases, but we are not using them anyway. Must not use "、". Must not use "让我们...、。相比传统的关系型数据库，XtremeData在并发场景下表现更稳，而且支持多种数据模型，比如文档、键值以及图形结构，让业务需求更灵活。我们在日常开发中经常会遇到数据量突然暴涨的情况，这时候XtremeData的自动分片功能能够把数据均匀分散到多个节点，避免单点瓶颈。更重要的是，它提供了友好的API接口，让新手也能快速上手，而不需要投入大量的专业培训。总的来说，XtremeData的出现让数据处理的门槛更低，效率更高，成为了很多团队的首选工具。" But we cannot use "总的来说". So remove that. Also avoid "并且". That's fine. But we used "总的来说". That's forbidden as a concluding phrase? It's not in the list but it's a summarizing phrase. The list only bans "、". "总的来说" is similar but not explicitly banned. Safer to avoid. Let's replace with something else.
We need to rewrite without "总的来说". Also avoid "而且". That's okay. "而且" is not banned. It's fine.
Let's rewrite paragraph 1 without "总的来说". Maybe end with "这让很多团队直接把它当作首选。" That's okay.
Now count characters. Let's approximate.
"XtremeData数据库是一款新兴的开源数据管理平台，它把实时处理和大规模查询结合在一起，让developers可以在几秒钟内完成数据的写入和读取。相比传统的关系型数据库，XtremeData在并发场景下表现更稳，而且支持多种数据模型，比如文档、键值以及图形结构，让业务需求更灵活。我们在日常开发中经常会遇到数据量突然暴涨的情况，这时候XtremeData的自动分片功能能够把数据均匀分散到多个节点，避免单点瓶颈。更重要的是，它提供了友好的API接口，让新手也能快速上手，而不需要投入大量的专业培训。这让很多团队直接把它当作首选。"
Now count characters (including punctuation). Rough estimate: each Chinese character ~1 char. Let's count quickly:
"XtremeData数据库是一款新兴的开源数据管理平台，它把实时处理和大规模查询结合在一起，让developers可以在几秒钟内完成数据的写入和读取。" That's about 45 characters? Let's approximate total later.
But we need 150-250 characters per paragraph. This paragraph seems maybe ~180 characters. Might be okay.
Now paragraph 2: talk about performance
