FOR u IN The default is false and will return the attribute names in any order. Getting Started with ArangoDB: Brief introduction of ArangoDB. The query optimizer recognizes correctly that the filter and the first sorting criterion are covered by the index on, so it removes them. sort (bool, optional): optionally sort the resulting array alphabetically. By default, no specific sort order is maintained for data in a collection. FOR t IN collection LET att REMOVEVALUES(SLICE(ATTRIBUTES(t, true, true), 0, 25), att) LIMIT offset, count RETURN KEEP(t, att) Tried executing the following AQL on ArangoDB 2.8.2 and doesnt seem to be performing a sort on the pr. We also need a mechanism for keeping highscores sorted. Collections are a general-purpose storage mechanism and they are not limited to storing just scores. RETURN KEEP(a, "_key", "name", "order", "datetime")ġ2 IndexNode 589 - FOR a IN activities /* reverse skiplist index scan */Ħ CalculationNode 589 - LET #5 = a.`order` /* attribute expression */ /* collections used: a : activities */ħ CalculationNode 589 - LET #7 = a.`_key` /* attribute expression */ /* collections used: a : activities */ġ0 CalculationNode 10 - LET #9 = KEEP(a, "_key", "name", "order", "datetime") /* simple expression */ /* collections used: a : activities */īy Type Collection Unique Sparse Selectivity Fields Rangesġ2 skiplist activities false false 37.29 % (a.`user_id` = "31132147") ArangoDB is a multi-model NoSQL database with a flexible data model for documents, graphs, and key-values collections. Instead, data in ArangoDB are stored in collections.
