| refs/heads/v1.4.x | 49d4352 | reduce size of publish failure response (#431) Fixes a bug where the failure message was getting encoded as a json string inside the message of the json response. Also changes the behavior on failures to have the error count explicitly in the response and limit the number of specific failure messages to the first 5. This significantly reduces allocations and response sizes for payloads with many failures. | 01 September 2016, 15:56:05 UTC |

By including in the v2.json format the UI/dashboard can use the static image and switch to a dynamic rendering without making another request. The message has a type of `graph-image` with a data field that is a data uri of the image without the legend.

The main reason is that under newer versions of akka there is a 5s subscription timeout for the underlying FanoutProcessor created with the Publisher. All other users of `asPublisher` were also converted unless the `Publisher` type was explicitly needed as part of the public API for the method. | 30 October 2020, 13:35:43 UTC |
| refs/tags/v1.7.0-rc.13 | 690d6ce | add topk/bottomk that aggregates others (#1248) Fixes #1224. Adds variants of topk/bottomk that in addition to computing the highest priority values will also return an aggregate time series that includes all of the other time series that were not high enough priority. This can be useful to see what proportion of the overall volume is represented by the highest priority time series. The operators have the same signature as `:topk` and `:bottomk`, but the aggregation to use is specified in the operator name. There are four aggregates supported: - min - max - sum - avg Count was not included as an aggregate because it could be ambiguous and does not seem useful. As part of this work there was some refactoring of the existing aggregation operations to make the count case more consistent. | 02 February 2021, 19:53:13 UTC |

Now it is part of a settings object which can be reused. The aggregators have also been refactored a bit to reduce code duplication. | 09 February 2022, 18:51:48 UTC |
| refs/tags/v1.7.0-rc.22 | 3f92628 | use sorted map when decoding tags (#1436) This is typically more efficient overall as it avoids the need to sort multiple times later on. For example, in publish the sort is needed for computing the ids and then ends up getting performed again to encode as a compact batch. | 18 April 2022, 19:56:17 UTC |
| refs/tags/v1.7.0-rc.23 | c5681f0 | update dependencies (#1441) | 04 May 2022, 18:19:53 UTC |
| refs/tags/v1.7.0-rc.24 | 3623642 | fix cg with custom averages (#1444) The subset check for nested grouping would check all data expressions. If the underlying expression was combined with binary operations with the grouping for one side being a subset of the other, then a subsequent grouping operation could fail the check. Now it checks based on the final grouping of the pre-aggregate. | 16 May 2022, 17:56:00 UTC |
| refs/tags/v1.7.0-rc.25 | 8c92e94 | fix `:cg` with non-grouped math aggregate (#1445) If there was an aggregation of a group by result that was not grouped, then it was not getting the common grouping applied. | 24 May 2022, 17:15:05 UTC |
| refs/tags/v1.7.0-rc.26 | 5a547c8 | update dependencies (#1453) | 08 August 2022, 22:30:35 UTC |
| refs/tags/v1.7.0-rc.27 | 18a2c6d | fix typo in config method name (#1460) | 01 September 2022, 16:09:51 UTC |
| refs/tags/v1.7.0-rc.28 | 82b412f | lwcapi: only update subscription list on changes (#1491) Creating the full list of of all subscriptions can be expensive when there are a lot of expressions. Update it to only be done when there are changes the same as the query index update. | 14 November 2022, 16:58:34 UTC |
| refs/tags/v1.7.0-rc.29 | ae06f6b | flush meters when a time grouping is emitted (#1496) When TimeGrouped flushes a finalized time grouping also have it explicitly flush the batch meter updaters. This avoids the counts potentially showing up much later due to a low rate. | 21 November 2022, 19:48:43 UTC |
| refs/tags/v1.7.0-rc.3 | f1d110e | simplify condition for isRestricted (#1112) The prefixes list is not used anywhere and it is faster as a simple condition. | 02 December 2019, 19:49:35 UTC |
| refs/tags/v1.7.0-rc.30 | 3fe64d9 | dedup query clauses during normalization (#1502) Update the normalization logic to deduplicate the same query clause within an conjunction. Also deduplicates terms within an IN clause and maps to an equals check if there is a single term. | 14 December 2022, 01:24:48 UTC |
| refs/tags/v1.7.0-rc.31 | c2dd5c3 | remove redundant clauses when normalizing (#1505) In some cases with tooling a `:cq` can get applied multiple times. If the common query condition has an OR clause, then that will get expanded with the cross product when computing the DNF. As a result, the normalized query resulting from applying a `:cq` once would differ from applying the same `:cq` multiple times. This change removes redundant clauses from the normalized OR set to avoid the discrepancy. Redundant means that the removed clause will not change the result since another branch of the OR would have matched. | 14 December 2022, 23:59:05 UTC |
| refs/tags/v1.7.0-rc.4 | 1ee176f | adjust default serialization for java.time (#1144) Set the default serialization to use millisecond timestamps. This keeps it more consistent with other usage in Atlas. | 11 February 2020, 17:22:15 UTC |
| refs/tags/v1.7.0-rc.5 | 832e827 | atlas-eval: expose flow api to maximize throughput (#1154) Converting to Processor disables operator fusion at the boundary, and reduces overall throughput. This change exposes the Flow directly and enables operator fusion optimization, and downstream delay of the boundary reduced from hundreds of microseconds to tens of microseconds. | 18 March 2020, 12:12:09 UTC |
| refs/tags/v1.7.0-rc.6 | 3e1aa52 | fix logic for skipNext (#1162) The `skipNext` helper did not work correctly in the case of some complex objects with nested arrays. This change fixes the logic and adds more extensive testing with randomly generated JSON objects. | 27 March 2020, 22:51:53 UTC |
| refs/tags/v1.7.0-rc.7 | 8a41771 | atlas-eval: fix eval flow failure on lwc instance removal (#1165) Currently the whole eval flow may fail when a lwc instance is removed. There's a subflow for lwc api call of each lwc instance, and that subflow is wrapped around by "RestartFlow" to enable auto-retry. The subflow is finished from upstream when a lwc instance is removed, and upstream of RestartFlow is finished, RestartFlow finishes and propagate the failure from the current ongoing attempt if any, to downstream, and eventually propagate to main flow. The fix is to have downstream of RestartFlow suppress the failure, since the failure is expected and can be ignored on lwc instance removal. | 02 April 2020, 22:14:21 UTC |
| refs/tags/v1.7.0-rc.8 | f096a18 | use jdk14 for travis build (#1174) OpenJDK14 has changes to font rendering that make it compatible with the lastest Zulu JDK11 we use internally. | 05 May 2020, 16:15:14 UTC |
| refs/tags/v1.7.0-rc.9 | 2887b4b | reduce allocations for asJavaMap.entrySet (#1197) Updates the `SmallHashMap.asJavaMap` implementation to override `entrySet()`. The new implementation avoids allocations for each item in the map. **Throughput** | Benchmark | Before | After | % Delta | |----------------------|---------------|---------------|---------| | customEntrySet | 8,400,934.3 | 13,480,190.3 | 60.5 | **Allocations** | Benchmark | Before | After | % Delta | |----------------------|---------------|---------------|---------| | customEntrySet | 296.0 | 24.0 | -91.9 | | 07 August 2020, 23:52:44 UTC |
| refs/tags/v1.7.1 | c366321 | ci: enable snapshots for version branches (#1537) Backport of #1536. | 03 April 2023, 14:10:48 UTC |
| refs/tags/v1.7.2 | 39561db | 1.7: update to jackson 2.15 (#1552) | 09 May 2023, 21:34:08 UTC |
| refs/tags/v1.7.3 | 9cbe657 | eval: fix aggr for group by with gauges (#1556) The `atlas.aggr` key was included when grouping the datapoints which caused values for the same key to go to separate buckets. | 24 May 2023, 13:08:35 UTC |
| refs/tags/v1.7.4 | 3931876 | eval: ensure exprs are resent on reconnect (#1558) If the websocket to an lwcapi node fails and needs to reconnect, then the message with the set of expressions needs to be resent. Before this would only happen when there was a change in either the set of remote instances or the set of expressions. With this change, the set of expressions will get repeated every 5s so it will get resent on a reconnect. Note, the websocket sub-flow already has some deduping if there is no change, so the additional overhead during normal operations is minimal. If there is a failure, then the sub-flow will get restarted and the state for the `unique` operator will get reset allowing the repeated expression message through. | 30 May 2023, 13:57:56 UTC |
| refs/tags/v1.7.5 | 4720431 | akka 2.6.21 (#1566) Pull in fix for spin loop in TLSActor. Backport of #1565. | 21 June 2023, 16:31:22 UTC |
| refs/tags/v1.7.6 | 5c3704b | 1.7: migrate from akka to pekko (#1576) | 15 September 2023, 22:20:40 UTC |
| refs/tags/v1.7.7 | acab86a | 1.7 eval: preserve state with multi-level grouping (#1580) When executing an expression in a streaming context, stateful operators used as input to a second level grouping were not preserving the state. Backport of #1579. | 19 September 2023, 23:06:58 UTC |
| refs/tags/v1.7.8 | 3144d87 | 1.7.x: add default values for interpreter execute (#1598) Update interpreter API to be more consistent with recent changes in 1.8. | 10 January 2024, 22:32:52 UTC |
| refs/tags/v1.8.0-rc.1 | 3e5fe07 | add log-linear scale type (#1548) It behaves like a log scale for powers of 10 with linear behavior in between. This helps spread out the smaller values. This can be useful for things like a heatmap view of percentile distributions. | 01 May 2023, 18:00:08 UTC |
| refs/tags/v1.8.0-rc.10 | fc5797e | eval: fix test case for trace time series (#1642) Update test case to have the correct expression for a trace time series subscription response. | 29 March 2024, 17:16:41 UTC |
| refs/tags/v1.8.0-rc.11 | 875a7f6 | lwcapi: fix status code for event without id (#1649) If an event is sent to `/evaluate` without an id, respond with a 400 error instead of 500. | 03 April 2024, 12:30:43 UTC |
| refs/tags/v1.8.0-rc.12 | aa364b7 | eval: use `ip` variable when creating web-socket (#1650) Remove references to instance-uri for the backend that are not used. Use the `ip` variable so it will work with IPv4 or IPv6. | 03 April 2024, 15:34:39 UTC |
| refs/tags/v1.8.0-rc.13 | c75e8fb | lwc-events: support enums as tag values (#1652) Add support for mapping Java Enum types to tag string values. | 10 April 2024, 21:16:09 UTC |
| refs/tags/v1.8.0-rc.14 | f50992c | roaringbitmap 1.0.6 (#1655) Pull in fix for ORing run containers. | 29 April 2024, 23:29:04 UTC |
| refs/tags/v1.8.0-rc.15 | 2216b69 | json: allow mapper to be customized (#1656) Provide method that can be used to customize the mapper. This should be used carefully as it will impact all uses of `Json` and could break other aspects that rely on the default behavior. | 06 May 2024, 14:39:42 UTC |
| refs/tags/v1.8.0-rc.16 | 647a464 | update dependencies (#1662) | 22 May 2024, 22:22:49 UTC |
| refs/tags/v1.8.0-rc.17 | bf81f55 | lwc-events: support duration for default value (#1670) When wrapping timer events it can be useful for the default value to be a duration for mapping to percentile timer type. | 23 June 2024, 21:08:40 UTC |
| refs/tags/v1.8.0-rc.18 | 055b549 | lwc-events: add pre-filter method for events (#1672) Add `couldMatch` method to the client to allow for filtering our some data early if it requires an expensive transform to generate the final event. | 10 July 2024, 15:46:53 UTC |
| refs/tags/v1.8.0-rc.2 | 6ce80af | add spring-lwc-events project to aggregate (#1554) It was overlooked and not getting published. | 17 May 2023, 00:15:34 UTC |
