Whereas in CQL the client can pass a timeout parameter to the server, in the DynamoDB API there is no such feature; The server needs to choose reasonable timeouts for its own internal operations - e.g., writes to disk, querying other replicas, etc. Until now, Alternator had a fixed timeout of 10 seconds for its requests. This choice was reasonable - it is much higher than we expect during normal operations, and still lower than the client-side timeouts that some DynamoDB libraries have (boto3 has a one-minute timeout). However, there's nothing holy about this number of 10 seconds, some installations might want to change this default. So this patch adds a configuration option, "--alternator-timeout-in-ms", to choose this timeout. As before, it defaults to 10 seconds (10,000ms). In particular, some test runs are unusually slow - consider for example testing a debug build (which is already very slow) in an extremely over-comitted test host. In some cases (see issue #7706) we noticed the 10 second timeout was not enough. So in this patch we increase the default timeout chosen in the "test/alternator/run" script to 30 seconds. Please note that as the code is structured today, this timeout only applies to some operations, such as GetItem, UpdateItem or Scan, but does not apply to CreateTable, for example. This is a pre-existing issue that this patch does not change. Signed-off-by: Nadav Har'El <nyh@scylladb.com> Message-Id: <20201207122758.2570332-1-nyh@scylladb.com>
