The change applies chunking by default on aggregated datafeeds. The chunking is set to a manual mode with time_span being 1000 histogram buckets. The motivation for the change is two-fold: 1. It helps to avoid memory pressure/blowing. Users may perform a lookback on a very long period of time. In that case, we may hold a search response for all that time which could include too many buckets. By chunking, we avoid that situation as we know we'll only keep results for 1000 buckets at a time. 2. It makes cancellation more responsive. In elastic/x-pack-elasticsearch#862 we made the processing of a search response cancellable in a responsive manner. However, the search phase cannot be cancelled at the moment. Chunking makes the search phase shorter, which will result to a better user experience when they stop an aggregated datafeed. Also note the change sets the default chunking_config on datafeed creation so the setting is no longer hidden. Relates to elastic/x-pack-elasticsearch#803 Original commit: elastic/x-pack-elasticsearch@ae8f120f5f
= Elasticsearch X Pack A set of Elastic's commercial plugins: - License - Security - Watcher - Monitoring - Machine Learning = Setup You must checkout x-pack and elasticsearch with a specific directory structure. The elasticsearch checkout will be used when building x-pack. The structure is: - /path/to/elastic/elasticsearch - /path/to/elastic/elasticsearch-extra/x-pack-elasticsearch == Native Code **This is mandatory as tests depend on it** Machine Learning requires platform specific binaries, build from https://github.com/elastic/machine-learning-cpp via CI servers. The native artifacts are stored in S3. To retrieve them infra's team Vault service is utilized, which requires a github token. Please setup a github token as documented: https://github.com/elastic/infra/blob/master/docs/vault.md#github-auth The github token has to be put into ~/.elastic/github.token, while the file rights must be set to 0600. = Build - Run unit tests: + [source, txt] ----- gradle clean test ----- - Run all tests: + [source, txt] ----- gradle clean check ----- - Run integration tests: + [source, txt] ----- gradle clean integTest ----- - Package X-Pack (wihtout running tests) + [source, txt] ----- gradle clean assemble ----- - Install X-Pack (wihtout running tests) + [source, txt] ----- gradle clean install -----
