Bank of America Backs MongoDB, Raises Price Target
Bank of America reiterated its buy rating on MongoDB and raised its 12-month price target to $540 from $450, citing accelerating AI adoption that boosts demand for data management systems. Analyst Koji Ikeda said MongoDB is positioned to win meaningful share of future AI workloads, praising its ability to handle large datasets, memory, scale, and real-time transactional data. The bank urged investors to view any fear-driven weakness as a buying opportunity. FactSet and LSEG data cited in the piece show MDB has rebounded strongly year-to-date and that the majority of Wall Street analysts rate the stock buy or strong buy.
- Bank of America reiterated its buy rating on MongoDB and raised its 12-month price target to $540 from $450.
- Bank of America analyst Koji Ikeda wrote that "MongoDB will win [a] meaningful share of future AI workloads."
- MongoDB was said to have rebounded 86% since March 31 and has more than doubled in the past year, per FactSet data.

Decoupling CRM from MDM for Device Management
The article describes an architecture for integrating Mobile Device Management (MDM) with an internal CRM without making the MDM a core dependency. Using NestJS, MongoDB/Mongoose, and TanStack Start with Fleet as the initial provider, the author separates business state (CRM-owned device records, device assignments, and immutable device action audit logs) from technical state (MDM-owned OS, hardware IDs, last check-in). Key patterns include a DeviceProvider abstraction (so different MDMs like Fleet, Intune, or Jamf can be swapped), a background DeviceSyncWorker that synchronizes technical device data into MongoDB every five minutes, and creation of DeviceAction audit records before executing destructive operations (lock/wipe) via the provider. The result is vendor independence, faster reads, auditable operations, and simpler frontend development.
- Author implemented an MDM-agnostic Device Management module using NestJS, MongoDB/Mongoose, and TanStack Start with Fleet as the initial MDM provider.
- The CRM owns three business concepts: Device (with a decoupled providerId), DeviceAssignment (historical ledger), and DeviceAction (immutable administrative audit record).
- A DeviceProvider interface defines required provider operations (getDevice, listDevices, lockDevice, wipeDevice); provider-specific implementations (e.g., FleetProvider, IntuneProvider) satisfy that interface.

How to Export FTDC From MongoDB Atlas
This technical how-to shows how to extract FTDC (Full Time Diagnostic Data Capture) from MongoDB Atlas using an undocumented Atlas Admin API (v1.0) that creates a log collection job, polls for success, and downloads a bundle containing per-member diagnostic.data directories including the live metrics.interim file. The author lists the three required inputs (programmatic API key, project ID, replica set name), provides example curl calls, and describes bundle metadata (expiration ~30 days). Atlas sets diagnosticDataCollectionDirectorySizeMB to 400MB, which typically yields 2–5 days of FTDC under real load (longer on idle clusters). The post also warns that the built-in clusterMonitor role grants read access to the oplog and demonstrates a more restrictive diagnostics-only custom role. The author references tooling (Big Hole, keyhole) for reading FTDC locally.
- MongoDB servers write FTDC (Full Time Diagnostic Data Capture) into a diagnostic.data folder with roughly 5,700 metrics sampled once per second.
- MongoDB Atlas exposes a v1.0 Admin API endpoint (logCollectionJobs) that can package FTDC on demand, requiring a programmatic API key, project ID, and replica set name.
- The FTDC extraction flow uses three API steps: create a logCollectionJob, poll the job until SUCCESS, and download the resulting bundle (example curl sequence provided).

Benchmark of Five Managed Graph Databases
A reproducible benchmark comparing CognoDB Cloud, Neo4j AuraDB, Memgraph, FalkorDB and ArangoDB revealed major pitfalls in naive measurement: geographic placement of managed instances skewed raw latency numbers, server-reported execution time (via Bolt drivers) is required for fair engine-to-engine comparison, and CognoDB v0.9.11 exhibited a background-indexing behaviour that caused indexed lookups to return no results while an index was building, silently dropping relationship writes. Concurrency characteristics differed: cloud-hosted databases scaled with client concurrency due to network latency hiding server idle time, while local instances became CPU-bound and slowed. The author published the full harness and raw data on GitHub.
- Five graph databases were benchmarked: CognoDB Cloud, Neo4j AuraDB, Memgraph, FalkorDB and ArangoDB.
- Geographic placement of managed cloud instances (e.g., CognoDB in Google Cloud us-east4 and Neo4j AuraDB in Google's Singapore range) skewed raw wall-clock latency measurements.
- Using server-reported execution time via Bolt drivers (network excluded) was necessary to fairly compare engines in different regions.

Benchmarking Five Graph Databases on 256MB RAM
The author benchmarked five graph databases (CognoDB, Neo4j AuraDB Free, Memgraph, FalkorDB, and ArangoDB) under a tight resource cap (0.5 vCPU / 256MB RAM) using a social-graph SNAP dataset (~18.7k nodes, ~198k edges). Results showed a range of operational and performance issues: Memgraph repeatedly segfaulted at startup across versions and configurations; FalkorDB lost all data after an environment restart due to an incorrect bind mount path and ignored persistence flags; Neo4j AuraDB exhibited a near-constant ~220ms per-query latency floor suggesting a fixed request cost; CognoDB was fastest on most queries but had one query pattern where it performed worst. Full methodology and raw results are available in the linked GitHub repository.
- CognoDB Cloud's free tier provides a graph database instance with 0.5 vCPU and 256MB of RAM.
- The benchmark compared CognoDB, Neo4j AuraDB Free, Memgraph, FalkorDB, and ArangoDB using the same ~18.7k-node / ~198k-edge SNAP dataset and identical query patterns under a 0.5 vCPU / 256MB RAM cap.
- Memgraph crashed immediately on startup with a reproducible segfault across multiple versions and with various runtime/configuration changes.

AI Agents Revive Ontologies and the Semantic Web
AI engineers and researchers are revisiting ontologies and Semantic Web technologies to provide logical guardrails for agentic systems built on large language models. At the AI Engineer World’s Fair, UC Berkeley professor Frank Coyle and Neo4j CEO Emil Eifrem argued that ontologies—described as "data as graphs"—can validate reasoning, enforce rules (e.g., OWL axioms), and enable a shared semantic layer for thinner, scalable agents. Practitioners like Kingsley Idehen (OpenLink Software) are combining RDF memory and Semantic Web stacks with agents, while developers suggest agents could maintain and update ontologies during operation. The article frames this as a 2026 revival of software engineering discipline focused on quality control for loop engineering in agent systems.
- Frank Coyle (UC Berkeley) reintroduced ontologies to AI engineers at the AI Engineer World’s Fair and described an ontology as "data as graphs."
- Neo4j is using ontologies in its agentic products; CEO Emil Eifrem described three ontology types: business-facing, technical (metadata), and execution traces.
- Kingsley Idehen of OpenLink Software is building an agent engineering stack that includes an "agent with RDF memory."
