You need to increase cache-max-memory-size. The default is 512mb which is fine for most workloads, but is too small for larger write volumes or higher cardinality datasets. If you have lots of RAM you could set it to 0 to disable the limit and never get that error. You can also examine the memBytes stat on cache measurement to get a sense of how big the caches are in memory once the limit is raised.
"cache-snapshot-memory-size" shouldn't be changed. Increasing it causes the cache in memory to be larger, which slows down snapshot compactions and increases startup time. The aborted compactions messages are informational and can be ignored. We will probably move those to trace level logging: https://github.com/influxdata/influxdb/issues/7425 On Wed, Oct 5, 2016 at 3:11 PM, Dmitriy Akulov <[email protected]> wrote: > Hello, I dont completely understand what this error means.
