Each tserver docker node has 25% cpu load in idle. [Annotation 2020-02-08 233739]

The user was working with YCQL api. He had 6 tservers in 1 node, 3 replicas, 3 masters, and created tables resulting in a big number of tablets. Had overhead because many tablets, 3 masters + 6tservers in same node and virtualization. Fixed by using with tablets when creating tables in dev enviro…

Hi @victor , Interesting. Wondering if there is some background task going on. Could you please answer a few questions about your setup, would help us identify what is going on: How many vCPUs on each yb-tserver pod? How many tables/tablets do you have in the system? You can find this from the mas…

I use docker-compose to setup cluster in dev environment (win10 + docker) - docker has 8 cpus for all services. 6 empty tables (created on db updater start). Yes. Logs in attach for tserver1. [Annotation 2020-02-09 204222] Logs: … W0209 18:34:10.465245 19 reactor.cc:380] TabletServer_R007: C…

Hello Victor, We have updated our reference docker-compose file at Deploy | YugabyteDB Docs recently. Please make sure your compose config looks similar to the reference. 25% usage on idle for 6 user tables does not match normal behavior. Were you running a benchmark or other workload prior to…

Hi. See attach. After start – db updater just created empty tables, no api activities, no inserts/selects, etc. I have api1x3 instances connected to each of 6 tservers and api2x3 instances connected to each of 6 tservers – so, 6 clients connected to each tserver. See attach. [BD60B217DAE648989F…

@victor you attachments are missing. Can you try again ?

Hi. Use this link to download reports: Perf_report P.S. I can attach only images to this thread.

The same issue on Ubuntu 18.04 VM: [image]

@victor Can you please provide a working docker-compose file ? Example: it misses version on top, misses services, has undefined network, etc. I tried with yb-docker-ctl multiple replicas and nodes and it worked fine: YugabyteDB Quick start for macOS Get started using YugabyteDB in l…

Hi. My docker-compose After start cpu load = 5-6%. 1 table - cpu = 8%. 2 tables - cpu = 12% [image] 4 tables - cpu = 18% 6 tables - 25% [image] P.S. Tables are empty, just created.
