Testing dynamodb-kv

[Graham Percival]

1. if one uses an invalid TABLE name and receives an AccessDeniedException, it would be helpful if the error was something other than

dynamodb-kv: parsenum failed on : Invalid argument

arising from dynamodb-kv/capacity.c, line 137. I can work on printing a better message for that.

2. when creating a DybamoDB table, what should the primary key / partition key be?

[Colin Percival]

1. Hmm, that looks like the parsing of consumed capacity is broken.

2. Partition key is 'K'. I think I specify the requirements in the lbs-dynamodb DESIGN file.

[Graham Percival]

Right, you did specify it there.

[Graham Percival]

I've created a table with partition key K. I'm now seeing:

$ TABLE=kivaloo-testing-gperciva make test
if [ -z "${HAVE_BUILD_FLAGS}" ]; then  cd ../..;  make BUILD_SUBDIR=tests/kvlds-ddbkv  BUILD_TARGET=test_kvlds buildsubdir;  else  make test_kvlds;  fi
. ./posix-flags.sh;				 . ./cpusupport-config.h;	 . ./cflags-filter.sh;				 export HAVE_BUILD_FLAGS=1;	 cd tests/kvlds-ddbkv && make test_kvlds
`test_kvlds' is up to date.
dynamodb-kv: callback_readmetadata: ResourceNotFoundException
dynamodb-kv: Error reading DynamoDB table metadata

Do I need to do additional setup for my table?

[Colin Percival]

ResourceNotFoundException means that the table doesn't exist. In addition to the obvious possibilities (wrong name or wrong region) it's possible that the table doesn't exist yet -- there's a temporary "CREATING" state before it can be used.

[Graham Percival]

Aha, us-east-1 vs. us-east-2.

[Graham Percival]

tests/kvlds-ddbkv/test_kvlds.sh contains:

$LBS -1 -s $SOCKL -t $SOCKDDBKV -b 512

which produces:

lbs-dynamodb: DynamoDB item size is unlikely to be optimal: 512

, arising from that binary checking (opt_b % 1024).

If we're deliberately checking a non-optimal value, I'd suggest a comment to that effect in test_kvlds.sh. But I wonder if one of those numbers should be changed.

The test_kvlds.sh and main.c were both added in 855b226.
