Archive storage is a data storage solution designed for long-term retention of infrequently accessed data. Archive storage is typically used to store information that should be retained but does not require frequent access. To meet users' long-term data retention and business requirements and maximize cost reduction for users, TencentCloud Managed Service for Prometheus (TMP) provides an archive storage feature. The following is a detailed introduction on how to use this feature.
Use Limits
Specifications limit: Archive storage can be configured only for instances with a data storage duration of 30 days or longer.
Retention period limit: The time range for archive storage with support for custom input. The configurable minimum value is 60 days, and the maximum value is 2 years.
Query frequency limit: If the queried data range includes archive storage data, the system will limit the query request frequency to a maximum of 3 times per second. When there is no query, the system will "cool down" and accumulate available quotas, with a maximum of 15 query quotas (approximately equivalent to 5 seconds of idle time). Therefore, you can initiate up to 15 queries at a time in a short time frame. (For example: If there are no query requests in the first 5 seconds, you can initiate up to 15 queries at a time in the 6th second. Then, the frequency will be restored to a maximum of 3 times per second.)
