Datadog's Log Rehydration feature allows organizations to efficiently archive and retrieve old logs for troubleshooting and analysis, overcoming challenges such as slow access, high costs, and lack of granularity in traditional log management solutions. With Log Rehydration, users can quickly rehydrate logs from cold storage into their Datadog account, analyze them using the Log Explorer, and perform root cause analysis without additional tooling or significant organizational overhead. The feature also enables organizations to organize old logs with archives, manage storage costs effectively, and gain greater visibility into their applications and infrastructure.
