In common-streams 0.8.x we shifted alerting / retrying / webhook out of the applications and into the common library. It also adds new features like heartbeat webhooks starting when the loader first becomes healthy. This commit also makes the webhook alert messages more human-friendly.
Compared to common-streams 0.8.0-M2, this version adds: - Re-implemented Kinesis source without fs2-kinesis - Pubsub source opens more transport channels when necessary - Changes default webhook heartbeat period to 5 minutes - Http4s Client with configuration appropriate for common-streams apps Other changes to common-streams are not relevant for snowflake loader, so not mentioned here.
Since the 0.2.4 release, the application logs contain lots of extra log lines, e.g.: ``` Oct 21, 2024 8:19:50 PM net.snowflake.client.jdbc.cloud.storage.SnowflakeS3Client upload INFO: Starting upload from stream (byte stream) to S3 location: <redacted>/streaming_ingest/2024/10/21/20/19/<redacted>_1003_24_0.bdec ``` This fix makes the snowflake sdk use SLF4J as the logger. Therefore it only logs at WARN or above by default.
See snowplow-incubator/common-streams#97 for details. This fixes an edge-case problem in which the loader did not properly load contexts if they were not JSON objects.
These changes allow the loader to better utilize all cpu available on a larger instance. **1. CPU-intensive parsing/transforming is now parallelized**. Parallelism is configured by a new config parameter `cpuParallelismFraction`. The actual parallelism is chosen dynamically based on the number of available CPU, so the default value should be appropriate for all sized VMs. **2. We now open a new Snowflake ingest client per channel**. Note the Snowflake SDK recommends to re-use a single Client per VM and open multiple Channels on the same Client. So here we are going against the recommendations. But, we justify it because it gives the loader better visiblity of when the client's Future completes, signifying a complete write to Snowflake. **3. Upload parallelism chosen dynamically**. Larger VMs benefit from higher upload parallelism, in order to keep up with the faster rate of batches produced by the cpu-intensive tasks. Parallelsim is configured by a new parameter `uploadParallelismFactor`, which gets multiplied by the number of available CPU. The default value should be appropriate for all sized VMs. These new settings have been tested on pods ranging from 0.6 to 8 available CPU.
* Bump common-streams to 0.9.0 See snowplow-incubator/common-streams#99 for the relevant change This library upgrade brings improvements to the Kinesis source, which should help on vertically larger instances. * Bump snowflake-ingest-sdk to 3.0.0
