pitrou commented on issue #1893: ARROW-2458: [Plasma] Use one thread pool per
PlasmaClient
URL: https://github.com/apache/arrow/pull/1893#issuecomment-382813255
As a sidenote, could someone explain what the goal of `PlasmaClient::Hash`
is? What is the use case of computing an object's hash?
Also, is the returned value meant to be stable? It seems to me that any
change to the pooling parameters (block size, number of threads) would give a
different result value. (Edit: indeed it does)
