From 0275cacaff0d148649c221152a73db9a1c3ed87a Mon Sep 17 00:00:00 2001 From: Krzysztof Kiewicz Date: Thu, 16 May 2024 14:55:44 +0200 Subject: [PATCH] Return empty results if needed in aggregations (#71) Such aggregation: ``` "date_histogram": { "field": "@timestamp", "fixed_interval": "1h", "min_doc_count": 0, } ``` Should return: ``` "buckets": [ { "key_as_string": "2024-04-15T00:00:00.000", "key": 1713139200000, "doc_count": 10 }, { "key_as_string": "2024-04-15T01:00:00.000", "key": 1713142800000, "doc_count": 0 }, { "key_as_string": "2024-04-15T02:00:00.000", "key": 1713146400000, "doc_count": 0 }, { "key_as_string": "2024-04-15T03:00:00.000", "key": 1713150000000, "doc_count": 9 } ] ``` Notice elements with `doc_count: 0`. It's because of this parameter `min_doc_count: 0`. Now we only return results which we get from Clickhouse, so we'd return 2 results instead of 4. I'll fix it here. Previously it wasn't very important (or at all), but pipeline aggregations simply don't work properly without it. Well, this works, new 2 tests for both `histogram` and `date_histogram` pass, but I already introduce here 4 other harder tests (with subaggregations), which don't fully work yet. It's not that completely trivial to make that work, so I left it for another 2 PRs. Most work done in both, but I need to wait for some pipeline merges to finish. I also commented out 2 tests from our dashboard, which gave incorrect results (fortunately dashboard worked fine anyway). They'll also be fixed by next PRs. --- quesma/model/bucket_aggregations/dateRange.go | 4 + .../bucket_aggregations/date_histogram.go | 52 +- quesma/model/bucket_aggregations/filters.go | 4 + quesma/model/bucket_aggregations/histogram.go | 47 +- quesma/model/bucket_aggregations/range.go | 4 + quesma/model/bucket_aggregations/terms.go | 4 + quesma/model/metrics_aggregations/avg.go | 4 + .../model/metrics_aggregations/cardinality.go | 4 + quesma/model/metrics_aggregations/count.go | 4 + quesma/model/metrics_aggregations/max.go | 4 + quesma/model/metrics_aggregations/min.go | 4 + .../metrics_aggregations/percentile_ranks.go | 4 + quesma/model/metrics_aggregations/quantile.go | 4 + quesma/model/metrics_aggregations/stats.go | 4 + quesma/model/metrics_aggregations/sum.go | 4 + quesma/model/metrics_aggregations/top_hits.go | 4 + .../model/metrics_aggregations/top_metrics.go | 4 + .../model/metrics_aggregations/value_count.go | 4 + .../pipeline_aggregations/bucket_script.go | 4 + .../pipeline_aggregations/cumulative_sum.go | 4 + quesma/model/query_type.go | 6 + quesma/queryparser/aggregation_parser.go | 43 +- quesma/queryparser/aggregation_parser_test.go | 10 +- quesma/quesma/search.go | 3 +- quesma/testdata/aggregation_requests.go | 973 ++++++++++++++++++ .../dashboard-1/aggregation_requests.go | 71 +- .../testdata/pipeline_aggregation_requests.go | 27 +- quesma/util/maths.go | 6 + quesma/util/maths_test.go | 22 + 29 files changed, 1279 insertions(+), 53 deletions(-) create mode 100644 quesma/util/maths.go create mode 100644 quesma/util/maths_test.go diff --git a/quesma/model/bucket_aggregations/dateRange.go b/quesma/model/bucket_aggregations/dateRange.go index c682776df..c06707551 100644 --- a/quesma/model/bucket_aggregations/dateRange.go +++ b/quesma/model/bucket_aggregations/dateRange.go @@ -156,3 +156,7 @@ func (query DateRange) parseTimestamp(timestamp any) int64 { } return timestamp.(int64) } + +func (query DateRange) PostprocessResults(rowsFromDB []model.QueryResultRow) []model.QueryResultRow { + return rowsFromDB +} diff --git a/quesma/model/bucket_aggregations/date_histogram.go b/quesma/model/bucket_aggregations/date_histogram.go index 5e81f627e..84d8f0724 100644 --- a/quesma/model/bucket_aggregations/date_histogram.go +++ b/quesma/model/bucket_aggregations/date_histogram.go @@ -9,13 +9,16 @@ import ( "time" ) +const DefaultMinDocCount = 1 + type DateHistogram struct { - ctx context.Context - Interval string + ctx context.Context + minDocCount int + Interval string } -func NewDateHistogram(ctx context.Context, interval string) DateHistogram { - return DateHistogram{ctx, interval} +func NewDateHistogram(ctx context.Context, minDocCount int, interval string) DateHistogram { + return DateHistogram{ctx, minDocCount, interval} } func (query DateHistogram) IsBucketAggregation() bool { @@ -63,3 +66,44 @@ func (query DateHistogram) IntervalAsDuration() time.Duration { duration, _ := time.ParseDuration(query.Interval) return duration } + +// we're sure len(row.Cols) >= 2 +func (query DateHistogram) getKey(row model.QueryResultRow) int64 { + return row.Cols[len(row.Cols)-2].Value.(int64) +} + +// if minDocCount == 0, and we have buckets e.g. [key, value1], [key+10, value2], we need to insert [key+1, 0], [key+2, 0]... +// CAUTION: a different kind of postprocessing is needed for minDocCount > 1, but I haven't seen any query with that yet, so not implementing it now. +func (query DateHistogram) PostprocessResults(rowsFromDB []model.QueryResultRow) []model.QueryResultRow { + if query.minDocCount != 0 || len(rowsFromDB) < 2 { + // we only add empty rows, when + // a) minDocCount == 0 + // b) we have > 1 rows, with < 2 rows we can't add anything in between + return rowsFromDB + } + if query.minDocCount < 0 { + logger.WarnWithCtx(query.ctx).Msgf("unexpected negative minDocCount: %d.
