| 2c50898 | brharrington | 01 September 2022, 11:56:16 UTC | 1.6: fix shard lookup for Integer.MIN_VALUE (#1459) Back port of #1452. Before it was relying on `abs` to get a non-negative value for computing an index to the array. This breaks when the int value of the id is `Integer.MIN_VALUE`. Update it to explicitly clear the sign bit to ensure the value will always be non-negative. | 01 September 2022, 11:56:16 UTC |
| 6b4665d | brharrington | 01 September 2022, 11:28:57 UTC | 1.6: re-enable doc artifacts (#1458) Back port of #1271. They were disabled due to a bug, but looks like it has been fixed. Fixed a number of scaladoc errors to get the build clean. Error from publishing attempt without docs: ``` Failed: javadoc-staging, failureMessage:Missing: no javadoc jar found in folder '/com/netflix/atlas_v1/atlas-module-lwcapi_2.13/1.7.0-rc.14' ``` | 01 September 2022, 11:28:57 UTC |

| dd715da | brharrington | 16 June 2020, 20:12:56 UTC | add support for dstype of sum (#1184) Backport of #1181. This should be used carefully as it could cause overcounting. The primary use-case is for inline aggregation of values that are already normalized to the step size. For example, the aggregator cluster could use this to avoid a multiple on counters that are flowing through. | 16 June 2020, 20:12:56 UTC |

For use-cases where we perform inline aggregation this gives the expected value and avoids the need for an additional disambiguation tag for the aggregator instance. This also means that if no custom rollups are done the sum of the gauge values would match expectations rather than being a multiple of the number of aggregator instances. | 16 June 2020, 19:48:38 UTC |

| 2b0996e | brharrington | 13 June 2019, 17:38:02 UTC | fix build settings for 2.13 to use `-release 8` (#1055) Before it was looking specifically for version 12. For now we still need to be able to run on jdk8+. The specific issue encountered was: ``` java.lang.NoSuchMethodError: java.nio.CharBuffer.clear()Ljava/nio/CharBuffer; at com.netflix.atlas.core.model.TaggedItem$.writePair(TaggedItem.scala:59) at com.netflix.atlas.core.model.TaggedItem$.computeId(TaggedItem.scala:105) at com.netflix.atlas.core.model.TimeSeries$.<clinit>(TimeSeries.scala:22) at com.netflix.atlas.core.model.EvalContext.<init>(EvalContext.scala:32) at com.netflix.atlas.druid.DruidDatabaseActorSuite.<init>(DruidDatabaseActorSuite.scala:259) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at java.lang.Class.newInstance(Class.java:442) ``` Also improves the check for recent JDKs. | 13 June 2019, 17:38:02 UTC |

For some of the custom collections they needed to be specific to the new version. Bump akka and jackson versions as the older versions do not have a published build for 2.13. | 05 June 2019, 23:42:56 UTC |

| c783b88 | brharrington | 30 April 2019, 23:41:51 UTC | fix empty data case for math/count (#1036) It wasn't checking if the input was empty like the other aggregate functions. Now it performs the same check which avoids errors like: ``` must have 1 or more time series to perform aggregation ``` | 30 April 2019, 23:41:51 UTC |
| 049a878 | brharrington | 30 April 2019, 16:54:42 UTC | fix eval state for sparse lines with group by (#1035) Before, if a line was sparse, for example an error counter that has a lot of gaps, the state would be handled incorrectly. There would be one state item per matching grouping when data was present and they would only get moved forward if there was data for that key in a given interval. For intervals with no data, a no data line would get pushed through and have its own independent state. With this change, an empty group by result will push an empty data set through eval and it will now move the state buffers to allow for expiration and correct handling of subsequent intervals with data. If there is no resulting data lines from the overall expression, then a no data line for the overall expression will be emitted to the user. | 30 April 2019, 16:54:42 UTC |
| 4550be9 | brharrington | 29 April 2019, 21:47:02 UTC | detect empty state and stop tracking it (#1034) Updates the online algorithms used with stateful operators to detect if the state is effectively empty. In that case the state will be dropped from the state map maintained during evaluation. This is useful to avoid leaking memory for tracking the state during long running streaming evaluations. There are currently three exceptions that have an unbounded window and never become empty: ignore-N, sdes, and integral. Integral is generally not very useful in a streaming context so we may just prohibit that operation. For sdes (and ignore-N which is typically only used to align sdes), the current uses do not involve group by operations, so it shouldn't be an issue for now. We'll revisit in the future when there are concrete use-cases that are problematic for that operation. | 29 April 2019, 21:47:02 UTC |
| a805a6a | brharrington | 26 April 2019, 22:19:07 UTC | fix tag results on MemoryDatabase.execute (#1031) The set of tags for the aggregated lines should be limited to the set that are exact matches in the query or are a part of a group by. Otherwise the grouping can have incorrect duplicates in the result set. Fixes #629. | 26 April 2019, 22:19:07 UTC |
| cca15bb | brharrington | 26 April 2019, 22:09:09 UTC | expire interned queries after 12h (#1030) Switches from a ConcurrentHashMap to a Cache for the interned queries. This avoids a slow leak over time with churn in the set of queries. In practice, we have not seen enough churn for it to matter, but now queries that are no longer in use will expire and go away. Fixes #729. | 26 April 2019, 22:09:09 UTC |
| bf69de1 | brharrington | 26 April 2019, 21:32:05 UTC | improve error message for invalid percentile data (#1029) The spectator-js client had a bug (Netflix/spectator-js#22) leading to duplicate values for a given count. This change updates the error message so it is easier to understand what is happening. Before it would just say `assertion failed`. | 26 April 2019, 21:32:05 UTC |
| 180fbaa | brharrington | 25 April 2019, 02:26:33 UTC | improve handling of empty legend string (#1028) Before it would fail with an error that is hard for a user to understand: ``` IllegalArgumentException: Can't add attribute to 0-length text ``` This error would only show up if the image legend was rendered causing further confusion because it wouldn't show up if the legend was suppressed. Now it will fallback to the default legend string if an empty string is specified. | 25 April 2019, 02:26:33 UTC |
| b3206fa | brharrington | 25 April 2019, 02:19:29 UTC | remove inline rollup hooks on the api (#1027) Partially reverts #525. This removes the plumbing for the ids and rollups via the api. The usage for the internal DB have been retained. The reason for this is it adds additional complexity and risk to the backends and for most use-cases we are moving to the simple aggregator cluster instead (see atlas-aggregator in iep-apps). As we are not planning to exercise this as scale anytime soon, it is being removed from the APIs before 1.6 release. | 25 April 2019, 02:19:29 UTC |

| 9ad7190 | brharrington | 22 February 2019, 06:17:23 UTC | add helpers for accessing materializer for stage (#995) In some cases, such as calling `discardEntityBytes` for an HTTP response, it is useful to access the materializer for the stage so the stream blueprint can be created without needing to pass in a materializer. | 22 February 2019, 06:17:23 UTC |

See #991 for more information. | 15 February 2019, 17:55:30 UTC |
| 6c3e280 | brharrington | 01 February 2019, 00:30:38 UTC | avoid BoxesRunTime.equals for SmallHashMap (#990) For the QueryIndex on the streaming clusters a hot spot is `SmallHashMap.get`. Flame graphs show a significant and unnecessary overhead being `BoxesRunTime.equals`. This change updates 7 places in the code to avoid that call: **Before** ``` $ javap -verbose ./atlas-core/target/scala-2.12/classes/com/netflix/atlas/core/util/SmallHashMap.class | grep Boxes 46: invokestatic #1101 // Method scala/runtime/BoxesRunTime.equals:(Ljava/lang/Object;Ljava/lang/Object;)Z 79: invokestatic #1101 // Method scala/runtime/BoxesRunTime.equals:(Ljava/lang/Object;Ljava/lang/Object;)Z 105: invokestatic #1101 // Method scala/runtime/BoxesRunTime.equals:(Ljava/lang/Object;Ljava/lang/Object;)Z 40: invokestatic #1155 // Method scala/runtime/BoxesRunTime.unboxToBoolean:(Ljava/lang/Object;)Z 29: invokestatic #1101 // Method scala/runtime/BoxesRunTime.equals:(Ljava/lang/Object;Ljava/lang/Object;)Z 59: invokestatic #1101 // Method scala/runtime/BoxesRunTime.equals:(Ljava/lang/Object;Ljava/lang/Object;)Z 17: invokestatic #1101 // Method scala/runtime/BoxesRunTime.equals:(Ljava/lang/Object;Ljava/lang/Object;)Z 2: invokestatic #1101 // Method scala/runtime/BoxesRunTime.equals:(Ljava/lang/Object;Ljava/lang/Object;)Z ``` **After** ``` $ javap -verbose ./atlas-core/target/scala-2.12/classes/com/netflix/atlas/core/util/SmallHashMap.class | grep Boxes 40: invokestatic #1154 // Method scala/runtime/BoxesRunTime.unboxToBoolean:(Ljava/lang/Object;)Z ``` | 01 February 2019, 00:30:38 UTC |
| d7e92dc | brharrington | 31 January 2019, 22:31:05 UTC | QueryIndex: reduce overhead for checking entries (#989) Flame graphs on the prod clusters show a bit of overhead for filter and exists calls on the list of entries. This change converts it to a simple array and avoids using the collections framework methods. For the existing JMH test this resulted in about a 12% improvement. | 31 January 2019, 22:31:05 UTC |
| 5f5166a | brharrington | 29 January 2019, 22:30:29 UTC | add rolling-mean operator (#987) This is meant as an alternative to `:trend` that fixes a number of issues with that operator. Specifically: 1. The denominator for the average is the number of actual values, that is non-NaN entries, within the rolling buffer. The `:trend` operator always uses the window size which can create confusing drops because `NaN` values are effectively 0. 2. The minimum number of values permitted before emitting a mean can be specified by the user. 3. It is more consistent with other stateful operators in that it works on a window size relative to the step interval rather than a fixed time duration. 4. It is more consistent with similar operators in other tools such as the `rolling_mean` function provided by Panda. Fixes #958. | 29 January 2019, 22:30:29 UTC |
