+ <description>
+ The buffering mechanism to use.
+ Values: disk, array, bytebuffer.
+
+ "disk" will use the directories listed in fs.s3a.buffer.dir as
+ the location(s) to save data prior to being uploaded.
+
+ "array" uses arrays in the JVM heap
+
+ "bytebuffer" uses off-heap memory within the JVM.
+
+ Both "array" and "bytebuffer" will consume memory in a single stream up to
the number
+ of blocks set by:
+
+ fs.s3a.multipart.size * fs.s3a.fast.upload.active.blocks.
+
+ If using either of these mechanisms, keep this value low
+
+ The total number of threads performing work across all threads is set by
+ fs.s3a.threads.max, with fs.s3a.max.total.tasks values setting the number
of queued
+ work items.
