A specific UUID version is not required or guaranteed. This extension
represents
UUIDs as FixedSizeBinary(16) with big-endian notation and does not
interpret the bytes in any way.
+8-bit Boolean
+====
+
+Bool8 represents a boolean value using 1 byte (8 bits) to store each value
instead of only 1 bit as in
+the native Arrow Boolean type. Although less compact that the native
representation, Bool8 may have
+better zero-copy compatibility with various systems that also store booleans
using 1 byte.
+
+* Extension name: ``arrow.bool8``.
+
+* The storage type of this extension is ``Int8`` where:
+
+ * **false** is denoted by the value ``0``.
+ * **true** can be specified using any non-zero value.
Review Comment:
@paleolimbot yes, we agree. See the comment I just posted above. I'm putting
emphasis on the producers sticking to `0` and `1` while suggesting that
consumers can assume the range, but don't have to trust it if they don't have a
good reason to.
