Addresses the problem of processes running out of memory when there are many ABFS output streams queuing data to upload, especially when the network upload bandwidth is less than the rate data is generated. ABFS Output streams now buffer their blocks of data to "disk", "bytebuffer" or "array", as set in "fs.azure.data.blocks.buffer" When buffering via disk, the location for temporary storage is set in "fs.azure.buffer.dir" For safe scaling: use "disk" (default); for performance, when confident that upload bandwidth will never be a bottleneck, experiment with the memory options. The number of blocks a single stream can have queued for uploading is set in "fs.azure.block.upload.active.blocks". The default value is 20. Contributed by Mehakmeet Singh. |
