What is the user trying to accomplish?
- Persona
- Engineering teams operating vector databases, RAG, and hybrid search
- Trigger
- A team needs to scale vector or sparse indexes, migrate storage, and preserve retrieval consistency during concurrent writes.
- JTBD
- When scaling vector or sparse indexes, migrating storage, or writing concurrently, reconcile index and storage state, plan a reversible migration, detect retrieval drift, and produce reproducible validation steps.
- Current workaround
- Engineers manually rebuild indexes, replay data, compare query results, and diagnose recall or consistency problems from logs and minimal reproductions.
- Desired outcome
- Reconciled index and storage state, a reversible migration plan, detection of recall drift, and reproducible validation steps.

“### Component: Vector Store (Qdrant, Python OSS SDK) ## Problem `search()` / `get_all()` / `delete_all()` filters that use the documented `"*"` wildcard (`{"key": "*"}` — "wildcard match (any value)", per the `Memory.search()` docstring in `mem0/memory/main.py`) are **silently discarded** by the Qdrant adapter. Points that do not have the filtered payload field at all match the filter, so results (and, via…”

“### Description This issue is not specific to a particular `qdrant-edge` release. All released versions and the current development branch that use the existing `OneshotFile::open()` implementation are affected. When a shard is stored on an F2FS filesystem in an Android-based environment, loading the existing shard can fail because `POSIX_FADV_NOREUSE` is called with `len = 0`. The shard files exist and are…”

“**Is your feature request related to a problem? Please describe.** Adding a BM25 sparse vector to a collection that already holds data requires reading every point out of Qdrant and writing it back, purely so Qdrant can tokenize a string it already stores. Since 1.18, we can add a named vector to an existing collection without recreating it, and the new vector is queryable immediately. It just returns nothing,…”

01Parse collection, index, and query configuration
02Compare stored data with retrieval behavior
03Generate migration, rollback, and retrieval regression tests
Human gates that must remain
- Engineers approve production index changes, backfills, and migration
- Recall metrics must be checked with real task data
Why is this not a solved or validated need yet?
Counterevidence / alternatives
- Managed vector databases already automate some operations.
- Small knowledge bases may not need dedicated infrastructure.
Evidence not yet obtained
- Whether index state can be represented consistently across engines
- The stable relationship between recall changes and task quality

Current reviewed evidence: 0 independent confirmations, 0 completed-action records, and 0 prototype-feedback records. A click, contact authorization, or development plan never upgrades the stage automatically.
Editorial judgment: The brief passed evidence-completeness and similarity checks. It is still a repeated-signal hypothesis, not customer, adoption, or product-market-fit evidence.

Any developer may submit a non-exclusive plan. A plan does not change the opportunity validation stage.
