Added asynchronous WriteBuffer support for Azure Blob Storage, enhancing performance for ClickHouse's experimental Azure object storage integration.
Why it matters
This feature addresses performance bottlenecks by enabling asynchronous buffering of writes to Azure Blob Storage, similar to the existing implementation for S3. It improves throughput and efficiency when writing data to Azure-based object storage, providing better resource utilization and faster data ingest.How to use it
To enable this feature, users should configure ClickHouse to use Azure Blob Storage as an external storage with the new asynchronous WriteBuffer enabled by default in the experimental Azure object storage settings. No additional configuration is typically required beyond setting up Azure credentials and storage endpoints.
