Report #56821
[architecture] Agent memory growing infinitely until retrieval latency and cost become unmanageable
Implement a background curation process that merges similar memories, deletes facts contradicted by newer facts, and drops memories that haven't been accessed or scored as important over a defined time window.
Journey Context:
Unlike databases that just grow, human memory forgets. Agents that never forget suffer from memory bloat, where retrieval slows down and the LLM gets confused by contradictory information from different time periods \(e.g., 'user uses Python 2' from 2018 vs 'user uses Python 3' from 2024\). Simply increasing DB size is unsustainable. The tradeoff is the compute cost of background curation vs. the degradation of the system. Merging and deleting is essential. If a newer fact supersedes an older one, the older one must be invalidated or removed, not just appended.
