Subject [GitHub] samza pull request #631: Invalid partition calculation in KafkaSystemProduce...
Date Mon, 10 Sep 2018 07:38:07 GMT
GitHub user voronenko-da opened a pull request:

    Invalid partition calculation in KafkaSystemProducer 0.14.1

    If you use a byte array as the key, the key.hashCode() will be different all the time.
Proposal to remove the preliminary calculation of the partition.
    val partitionKey = if (envelope.getPartitionKey != null) KafkaUtil.getIntegerPartitionKey(envelope,
partitions) else null
      def getIntegerPartitionKey(envelope: OutgoingMessageEnvelope, partitions: java.util.List[PartitionInfo]):
Integer = {
        val numPartitions = partitions.size
        abs(envelope.getPartitionKey.hashCode()) % numPartitions

    SAMZA-1705: Switch to use snapshot in iterable impl of RocksDb
    We should use rocksDb.snapshot() method to keep the snapshot and creates a new iterator
with it all the time. The perf shows a little bit more expensive but mostly on par with range
iterator query.

    SAMZA-1706: lazy initialization for eventhub system producer
    We are seeing slow shutdown issue for eventhub system producers for users who only use
eventhub consumer (but then Samza system creates both consumer and producer together no matter
what). As a workaround, add lazy initialization to the producer to avoid the slow shutdown

    Fixed test failure for TestRocksDbKeyValueStoreJava#testIterate
    RocksDB Snapshots and any iterators obtained from them need to be closed before the store
is closed.
    Otherwise the process aborts with the following message (at least on OSX):
    `Assertion failed: (is_last_reference), function ~ColumnFamilyData, file db/,
line 457.`

    SAMZA-1720: Remove javafx.util dependency from samza-sql tests.
    In samza-sql module, currently few test classes(`TestSamzaSqlRelMessageSerde` and `TestSamzaSqlRelRecordSerde`)
are dependent upon `javafx.util.Pair` class(coming from `javafx` module). `javafx.util.Pair`
is not supported by default in all JDK builds(example; open-jdk java-8 doesn't support `javafx`
module) and it belongs to `javafx` package which is primarily used for developing GUI applications.
This dependency is removed and replaced with `Pair` class from `apache-commons`.

    Implementing the fetchSinkInfo in ConfigBasedIOResolver
    1. I think we missed implementing the fetchSinkInfo method in the ConfigBasedResolver
when the API was introduced which is breaking the samza sql console tool. This fixes it.
    2. latest release of mac removed realpath so the command line tools are broken. Removed
the usage of realpath to fix these tools.
    Thanks to nickpan47 for identifying these problems.
