Cloudflare Workflows v2026-09-10：Paid计划默认实例保留期由30天缩
Workflows - Default instance retention for new Workflows on Workers Paid is seven days
依赖Cloudflare Workflows处理长尾任务或故障排查的开发者请注意：新工作流默认日志/状态保留期已大幅缩短。若你的流程依赖事后回溯超过7天的执行记录，务必在创建时显式设置更长的保留期，否则数据将提前丢失。
Workflows created on or after September 10, 2026, on the Workers Paid plan retain completed and errored instance state for seven days by default (previously 30 days). The seven day default helps to reduce storage costs by default. The maximum retention limit remains 30 days.
在 Workers Paid 计划上于 2026 年 9 月 10 日或之后创建的工作流，默认保留已完成和出错实例状态七天（此前为 30 天）。七天的默认值有助于降低存储成本。最大保留期限仍为 30 天。
The retention period for existing Workflows is unchanged. The Workers Free plan retains its three-day default and limit.
现有工作流的保留期限保持不变。Workers Free 计划保留其三天默认值和限制。
To set the retention period for a Workflow instance, specify successRetention, errorRetention, or both:
要设置工作流实例的保留期限，请指定 successRetention、errorRetention 或两者：
const instance = await env.MY_WORKFLOW.create({
retention: {
successRetention: "2 days",
errorRetention: "30 days",
},
});const instance = await env.MY_WORKFLOW.create({
retention: {
successRetention: "2 days",
errorRetention: "30 days",
},
});const instance = await env.MY_WORKFLOW.create({
retention: {
successRetention: "2 days",
errorRetention: "30 days",
},
});const instance = await env.MY_WORKFLOW.create({
retention: {
successRetention: "2 days",
errorRetention: "30 days",
},
});You can also set the retention period per Workflow and per instance in the Cloudflare dashboard ↗.
您还可以在 Cloudflare 控制面板 ↗ 中按工作流和每个实例设置保留期限。
