    Has anyone gotten the docker streaming QuickStart to work recently? When I try, docker container dies after a couple seconds with an exit code of 1.

    Copy code
    # stop previous container, if any, or use different network
    docker run \
        --network=pinot-demo \
        --name pinot-quickstart \
        -p 9000:9000 \

    folks, per https://readthedocs.org/projects/pinot/downloads/pdf/latest/
    Copy code
    FASTHLL (WARN: will be deprecated soon. FASTHLL stores serialized HyperLogLog in String format, which
    performs worse than DISTINCTCOUNTHLL, which supports serialized HyperLogLog in BYTES (byte array)
    format)
    is there documents about the difference between
    fasthll
    and
    distinctcounthll
    ?

    fasthll is used before bytes supported, so we use string to represent hyperloglog object

    Xiang Fu

    03/12/2020, 5:04 PM
    distinctCountHll is on bytes column

    other than the input formats, are there other impl differences?

    cool. for porting from fasthll to distintcounthll, whats the suggested function for converting the input from string to bytes?

    Yupeng Fu

    03/12/2020, 5:06 PM
    btw, is there a plan to add some docs like https://prestodb.io/docs/current/functions/hyperloglog.html that clearly describes the input/output and the semantics?

    Question: can incomingGranularitySpec convert string columns in the format of
    2020-03-13T11:51:46.075-07:00[America/Los_Angeles]
    ? Or would you recommend just using epoch? For the primary time column.

    Has anyone here gotta an AWS Lambda to send messages to a Kafka started using the AWS EKS Pinot/Kafka instructions? I followed Kafka's NodePort and they didn't work. I figured someone else has gotten this to work and can forward advice.

    I haven’t tried out lambda, please let me know if you make this pipeline working, it will be a good story to put up.

    Hello. We are trying to choose OLAP solution for our project and we are considering Pinot. First question that we have: Is it possible/efficient to aggregate only on LATEST metric value for targets = "Give me current average CPU usage across all targets"? (maybe with some workarounds, additional tables etc.) I read pretty interesting article regarding workarounds for Clickhouse here: https://www.altinity.com/blog/clickhouse-continues-to-crush-time-series and "lastpoint"+"groupby-orderby-limit" cases of TSBS Time series benchmark and I am wondering how Pinot could deal with those cases.

    Pinot does not support it. We can add a special operator to achieve this
