access to fielddata must be fast, which is why it is loaded into memory. But loading too much data into memory will cause slow garbage collections as the JVM tries to find extra space in the heap, or possibly even an OutOfMemory exception. ...
so once the cache fills the least accessed data is removed or evicted. Similar to field data, it is a good idea to bound how much memory can be devoted to your query cache using theindices.queries.cache.sizesetting
Set the minimum heap size (Xms) and maximum heap size (Xmx) to be equal to each other. 将最小堆大小(Xms)和最大堆大小(Xmx)设置为彼此相等。 The more heap available to Elasticsearch, the more memory it can use for caching. But note that too much heap can subject you to long garbage ...

reduced,the computing capacity will be reduced; Thus, ES typically use high-spec machines for hot nodes and use low-spec machines for cold nodes; But don’t make too much memory reduction, as it decreases ES performance. For code nodes, we prefer using lower frequency CPUs, o...
Remember that it is advisable to ensure that all data nodes are of the same RAM memory and disk size, since the shards balance on the basis of number of shards per node. The process would be: Add new, smaller nodes to the cluster Migrate the shards away from the nodes to be ...
files created by the dump. Files created with version0.x.xof this tool are likely not to work with versions going forward. To learn more about the breaking changes, vist the release notes for version1.0.0. If you recive an "out of memory" error, this is probably or most likely the ...
In other cases, set it to 50% of the machine memory divided by the number of instances. Do not set -Xmx to be greater than the value of cutoff (compressed oops) that is used by the JVM to compress the object pointer. The cutoff value may be different but is close to 31 GB. ...
activate bulk mode. For that to work effectively, we use an in-memory queue that can hold up to 5000 events. The maximum bulk size will be 300 retry indefinitely if the HTTP request failed (eg: if the target server is down) module(load="omelasticsearch") template(name="testTemplate" ty...
