Hi, I am building a shared elasticsearch cluster (4 nodes) that will be used by several projects (at least 4). Because each project need to control configuration, node restart, and version upgrades, a single cluster with multi-tenant is not an option. Some projects will have few documents indexed (10K docs of 1 KB per doc), but will be querried massively. Other project will receive logs continuously. Logs will be deleted after some month. But documents will not be querried often. I am looking for any feedbacks how to configure my different ES processes : - Is LVM a goog idea to ensure disk quota ? - is Xmx enough to isolate process memory or should I use memory cgroup[https://www.kernel.org/doc/Documentation/cgroups/memory.txt](https://www.kernel.org/doc/Documentation/cgroups/memory.txt) ? - What is the miminum memory advised for each process ? - should mlockall be enabled on each ES ? - should I set some limitation on the network ? Thanks for your help. Romain -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
