From d93b2a2e9a68ae4defd5949fcc5eb945a26395bf Mon Sep 17 00:00:00 2001 From: Zachary Tong Date: Wed, 29 Aug 2018 17:10:00 -0400 Subject: [PATCH] [Rollup] Only allow aggregating on multiples of configured interval (#32052) We need to limit the search request aggregations to whole multiples of the configured interval for both histogram and date_histogram. Otherwise, agg buckets won't overlap with the rolled up buckets and the results will be incorrect. For histogram, the validation is very simple: request must be >= the config, and modulo evenly. Dates are more tricky. - If both request and config are fixed dates, we can convert to millis and treat them just like the histo - If both are calendar, we make sure the request is >= the config with a static lookup map that ranks the calendar values relatively. All calendar units are "singles", so they are evenly divisible already - We disallow any other combination (one fixed, one calendar, etc) --- x-pack/docs/build.gradle | 3 +- .../docs/en/rest-api/rollup/put-job.asciidoc | 2 + .../rollup/rollup-job-config.asciidoc | 50 +++++- .../en/rollup/rollup-getting-started.asciidoc | 124 +++++++------- .../rollup/rollup-search-limitations.asciidoc | 22 ++- .../rollup/RollupJobIdentifierUtils.java | 101 +++++++++-- .../rollup/RollupJobIdentifierUtilTests.java | 160 ++++++++++++++++++ .../elasticsearch/multi_node/RollupIT.java | 2 +- 8 files changed, 380 insertions(+), 84 deletions(-) diff --git a/x-pack/docs/build.gradle b/x-pack/docs/build.gradle index 6cca05c4a0ef..99e62532e2dc 100644 --- a/x-pack/docs/build.gradle +++ b/x-pack/docs/build.gradle @@ -685,9 +685,8 @@ setups['sensor_prefab_data'] = ''' page_size: 1000 groups: date_histogram: - delay: "7d" field: "timestamp" - interval: "1h" + interval: "7d" time_zone: "UTC" terms: fields: diff --git a/x-pack/docs/en/rest-api/rollup/put-job.asciidoc b/x-pack/docs/en/rest-api/rollup/put-job.asciidoc index 1449acadc636..27889d985b8c 100644 --- a/x-pack/docs/en/rest-api/rollup/put-job.asciidoc +++ b/x-pack/docs/en/rest-api/rollup/put-job.asciidoc @@ -43,6 +43,8 @@ started with the <>. `metrics`:: (object) Defines the metrics that should be collected for each grouping tuple.
