Socialite is a reference architecture for modeling, querying, and aggregating social data feeds.PY-TPCC, our adaption of the TPC-C benchmark for MongoDB, implemented in Python.MongoDB Labs maintains a YCSB repo to test simple key-value operations.If you just want to evaluate different Atlas tiers or hardware configurations without creating your own test harnesses, then consider the following:
Nosql benchmark tests free#
Free monitoring collects a range of metrics including operation execution times, memory and CPU usage, and operation counts, retaining the data for 24-hours.
Nosql benchmark tests install#
You don’t need to install any agents or complete any forms to use the service. If you are running MongoDB in your own environment, the Free Monitoring cloud service is the quickest and easiest way to monitor and visualize the status of your MongoDB deployment. Ops Manager, available as a part of MongoDB Enterprise Advanced provides the same deep monitoring telemetry when running MongoDB on your own infrastructure.įor instant visibility into operations, the Real-Time Performance Panel (RTPP) monitors and displays current network traffic, database operations on the machines hosting MongoDB in your clusters, and hardware statistics about the hosts.įigure 1: The Real-Time Performance Panel provides visibility into MongoDB performance as operations are in-flight Free Monitoring Service The metrics are securely reported to Atlas where they are processed, aggregated, alerted, and visualized in a browser, letting you easily determine the health of MongoDB over time. MongoDB Atlas features charts, custom dashboards, and automated alerting, tracking 100+ key database and systems metrics including operations counters, memory, and CPU utilization, replication status, open connections, queues, and any node status. These tools also provide fine-grained telemetry and observability across all components of your database cluster.
Nosql benchmark tests series#
We covered query and index profiling in parts 2 and 3 of this blog series using tools like the explain plan, MongoDB Atlas Data Explorer, and Compass. Whether running a benchmark or production workload, it is important to monitor your deployment. Monitor Everything to Locate Your Bottlenecks It is also important to configure ulimits. Review connection pool options in the documentation. Re-opening connections for each operation takes time, especially if TLS is used. MongoDB must first read the working set into RAM, so prime the system with representative queries for several minutes before running the tests to get an accurate sense of how MongoDB will perform in production. In a production MongoDB system the working set should fit in RAM, and all reads and writes will be executed against RAM.

Prevent the balancer from rebalancing data unnecessarily during bulk loads to improve performance.

If your data is sorted in shard key order, then you can use hash based sharding to ensure that concurrent inserts of nearby shard key values will be routed to different shards. You should design your data load such that different shard key values are inserted in parallel, into different shards. This will void any benefit from adding multiple shards, as only a single shard is active at a given time. If you configured range based sharding, and load data sorted by the shard key, then all inserts at a given time will necessarily have to go to the same chunk and same shard. If your benchmark does not include range queries, you can use hash-based sharding to ensure a uniform distribution of writes and reads.

By pre-splitting the data, documents will be loaded in parallel into the appropriate shards. Without pre-splitting, data may be loaded into a shard then moved to a different shard as the load progresses. When creating a new sharded collection, pre-split chunks before loading. Similarly, to reduce the overhead from network round trips, you can use bulk writes to load (or update) many documents in one batch.

Use Multiple Parallel ThreadsĮspecially for a sharded cluster, and certain configurations like writeConcern majority, latencies for a single operation can be significant, and using multiple threads is necessary to drive good throughput. The following considerations will help you develop benchmarks that are meaningful. We instead recommend that you model your benchmark using the data, queries, and deployment environment that are representative of your application. Generic benchmarks can be misleading and mis-representative of any technology and how well it will perform for a given application.
