ArangoDB's Series A investment will allow it to accelerate product development and revenue growth by further expanding its engineering and sales teams to more heavily support its customers and community in the U.S. More than 500 organizations worldwide, including Airbus, Barclays, SAP Concur, and Thomson Reuters, leverage ArangoDB's multi-model database in production for flexible, streamlined application development. Existing investor Target Partners also participated in the round, bringing ArangoDB's total financing to $17 million. As part of the investment, Bow Capital Advisor Murat Sonmez, a former EVP of Global Field Operations at TIBCO and Managing Director at the World Economic Forum, joins ArangoDB's board of directors. to better service its fastest-growing market.
The first snapshot was taken shortly after startup completed, while the seventh was taken shortly before the OOMKill event.ArangoDB, the leading open source native multi-model database, today announced it has raised $10 million in a Series A financing led by Bow Capital, and has moved its headquarters to the U.S. I will see if it is possible to create a sample program to reproduce this, though it may be I took measurements at seven different times (I'll call them snapshots) during the course of a single container's lifecycle. Please advise what my next steps should be in debugging/collecting data. # the user and group are normally set in the start scriptĪrangodb: WARNING slow background settings sync: 1.379094 s # number of threads automatically, based on available CPUs # reuse a port on restart or wait until it is freed by the operating system # Specify the endpoint for HTTP requests by clients. With rocksdb, we are hitting 16GB and getting OOMKilled.
In this same environment, if we run with mmfiles, the container typically consumes <1GB of memory and never more than 6GB. If I run enough concurrent queries, I can force the OOMKilled event to occur. I seem to see a correlation between the queries being run, and the memory usage increasing. However, we don't have very many concurrent consumers. We'll have queries running against this data, some of which can take several minutes to execute. We will typically have 3-4 databases before the pruning kicks in. We prune our databases periodically, keeping only the two most recent. We load new data in about every 10 minutes, resulting in a a new database of ~1GB. Regarding workload, we are working with a few gigabytes of data at a time.

I will have to install something that lets me see how much of the growth is RSS vs. The tools (ctop) I'm using to monitor currently don't provide that level of granularity, but I believe other tools do. Therefore, it's possible that not all the usage is RSS, the page cache could account for some of it. ".the total resident set size (RSS) and page cache usage of a container." Regarding the memory usage figures that I am monitoring-apparently in Kubernetes memory usage is equal to: How can we constrain the memory usage so the container does not get OOMKilled? It seems very hard to manage the arangoDB memory usage with RocksDB enabled. However, it takes only a few minutes of traffic hitting arangodb to exhaust the entire 16 GB and cause an OOMKilled event. However, this has not impacted our observed performance.ĭespite the stringent cache settings, we are allocating a memory limit of 16Gi for this pod. Startup-directory = /usr/share/arangodb3/jsĪs you can see, we have already disabled statistics and foxx queues based on earlier suggestions in the comments of this issue.
