v0.1.2

Release Date: 2024-08-19 | Status: archived

This release has been archived due to a regression in the transaction processing system. All production workloads should continue to use version 0.1.1.

Bug Fixes

• Fixes error-handling bug in topic auto-creation
• Reduces error probability when Bufstream attempts to calculate the last stable or next unstable offset
• Resolves error when Bufstream attempts to read the kafka.public_address value in the Helm chart
• Prevents Bufstream from sending empty values for CPU memory limits by setting a reasonable default in the Helm chart
• Assigns all transactions a monotonic number so that concurrent complete operations no longer result in transactions completing multiple times for a topic partition -- Bufstream now applies only the first completion for a given transaction number
• Addresses checkpoint error when Bufstream attempts to archive internal topics

Features and Improvements

• Expands Bufstream's Kafka conformance testing suite
• Exposes Kafka configs in the Helm chart so that they can be set directly
• Adds documentation for the Helm chart and recommended defaults
• Improves debug log output for transaction state changes
• Uncaches transactional producers to expose state transition errors
• Allows topic replication factor to be set to -1 -- in cases where the topic replication factor is not set to -1 or 1, Bufstream will return an error
• Improves compatibility with RedPanda console when displaying topics and offsets

v0.1.0

Release Date: 2024-08-09

Features and Improvements

• Adds helm value exact_log_sizes that determines whether exact log sizes should be fetched for all topics and partitions
• Documents dynamic configuration options
• Adds configuration options for consumer group session timeout: group.consumer.session.timeout.ms, group.consumer.min.session.timeout.ms, group.consumer.max.session.timeout.ms

v0.0.4

Release Date: 2024-08-06

Bug Fixes

• Fixed memory leak when uploading objects to S3 storage
• Removed redundant zone lookups when resolving metadata requests
• Fixed Fetch response to work with librdkafka-based clients (including the confluent-kafka Python client)

v0.0.3

Features and Improvements

• Set etcd connection wait time to 2 minutes -- Bufstream will return an error and shut down if it cannot establish a connection to etcd within the 2 minute interval
• Provide traces for all etcd storage errors
• Improve topic metadata management
• Change shut down behavior such that Bufstream will wait for the archiver to finish before shutting down
