Hi Team. I have a PR open from some days. Can someone please review it. TIA !

Hi, I have a small PR for documentation update; https://github.com/apache/druid/pull/17409 ; can someone help review it? Thanks!

Do we support

druid.emitter

for

composing

type for

parametrized

with

dropwizard

together.?

Hi team, do we have a direct way to connect to flink as Source ? I usually see examples flink->kafka->druid. Please share any reference/discussions on this.

Hello! We were wondering if we could get rid of the intellij-inspections check from Apache Druid repo. Reasoning: 1. We have

maven-checkstyle-plugin

plugin integrated which uses checkstyle.xml. 2. We also have spotbugs integrated in our CI pipeline which does static analysis as well With the above, it seems a bit redundant to have a separate intellij-inspections check. It also adds unnecessary maintenance overhead. We are currently using https://github.com/ccaominh/intellij-inspect which is tied down to an openjdk8 image, and the project doesn't seem to be actively maintained. We would appreciate your thoughts and inputs on the above. If it sounds good, we will work on removing the check from the repo. Thanks!

Hey, there is this issue regarding javascript engine in regards of JDK17+. I'd like to hear from you on your stance about it. https://github.com/apache/druid/pull/14795 - this PR proposed using Nashorn standalone (not compatible with JDK < 11). Since the JDK17 is recommended, least change there should be is to update documentation.

Hello! We recently removed support for Java 8, and we were hoping to discuss the same for Java 11. Please let us know your thoughts and any concerns with removing support for Java 11. Thanks!

Hi, A small PR for documentation update for SQL metrics : https://github.com/apache/druid/pull/17554 Can someone kindly help review it? Thanks!

👋 Hello, team!

Please be informed that, already we have a JAVA application which is deployed on Oracle Weblogic 12c and we need to connect our application to druid via Weblogci JDBC connection. But I couldn't find a library and instruction for Connecting Weblogic to Druid. So appreciated to assist me in this regard

Hey all, seeking a clarification on our Java support matrix: When we say java 17 is fully supported since druid 27, are we talking strictly about the core druid project code and not about the dependencies we are pinning in our pom files? • For example, we depend on guice 4.2.2 (in master, druid27 is actually guice 4.1.0), which doesn't publicly support java 17 until 5.1.0.

Druid supports Long as a basic type for dimensions. But ingesting integer values as dimensions also works which means Druid is casting Integers to Long type somewhere while reading the segment. Could somebody help me understand how this casting works or point to the class which may be responsible for this? Thanks!

Hi! Could I get reviews on this PR when they have the time? https://github.com/apache/druid/pull/17439 Would be great to have it in v32. Thanks!

What do people think about emitting a histogram for Druid metric emission? I think currently all the metric values are just numbers

Hi Team, Can someone please review this PR. TIA!

Hi Team, Please review this PR to improve S3 upload speed.

I am working with Apache Druid 31.0.1 and I need to apply a spatial filter using a polygon shape. Specifically, I want to filter data based on whether a point falls within a given polygon. Can anyone provide an example of how to set up and use spatial filters with polygons in Druid? I’ve read through the documentation and tried using various filter options, but I’m having trouble with the correct syntax for defining the polygon in a spatial filter. I would appreciate any examples or pointers on how to structure this in Druid 31.0.1. there is no example of using polygon in spatial filters in druid's official documentation. any help will be appreciated

Can I get a quick review on https://github.com/apache/druid/pull/17652? Thanks!

Hi there! I'm the guy who added rabbitmq superstream ingestion to druid. It's been working well for us, thanks for the help getting it integrated! We've been using druid-exporter to get statistics out to Prometheus, and we used to have rabbitmq ingest stats to use in monitoring, like

druid_emitted_metrics{metric_name="ingest-rabbit-lag"}

. We've recently switched to using the Prometheus plugin, but I can't find any rabbit ingest stats. Am I missing anything? Can anyone point me to what I would need to change to get these stats back?

Hey all! Looking for input on how to prevent compaction tasks from publishing overlapping segments. Here's what happened: • Auto-compaction was running every 30 minutes, compacting daily-partitioned data. • A manual compaction reindexed the same period with a different granularity. • Once the manual compaction finished, some previously scheduled auto-compaction tasks (created before the reindexing) started running. • These tasks compacted data with the old granularity, causing a mix of granularities and overlapping segments (daily segments were created inside of monthly one). • After the data was successfully compacted, things stabilized. For a fix, we need to prevent autocompaction from publishing overlapping segments. We know which segments will be published only at the InputSourceProcessor level on the worker. The indexing task has a

coordinator-issued

prefix, which helps identify auto-compaction and could be used to check and reject publishing segments that don’t match the current cluster state. The problem is that this prefix isn’t accessible on the level where segments are being chosen. The options are to add some preprocessing of the input source at generateAndPublishSegments in IndexTask or to send some flag to the InputSourceProcessor.prosess() method, but both feel like a last resort. Curious to hear your thoughts — if not there, where do you think this could be best handled?

We can’t include dependency on GNU General Public License v2.0 library right?

Would it be possible to have the SegmentMetadata queries return distinct values of a column? Similar to how it already supports cardinality, this would just be looking at the keys in the string column dictionaries?

Do we have any plan on extending query lane to Historical and realtime ingestion task (i.e. Peons)? Having query lane only on the broker makes it less useful. For example, a single very expensive query (which would run on low lane on broker) could/would still takes up all the processing thread on historical and blocks other query from running on those historical. CC: @Clint Wylie (as author of the query lane on the broker). Thanks!!

A fix for the

json_merge()

function when someone gets a chance: https://github.com/apache/druid/pull/17983. Thanks!
