Ehren Kret 0dcb4b645c Build Dynamo DB backed Message Store (#358 ) * Work in progress... * Finish first pass draft of MessagesDynamoDb * Use begins_with everywhere for destination device id * Remove now unused methods * First basic test built * Add another test case * Remove comment * Verify more of the message contents * Ensure all methods are tested * Integrate MessagesDynamoDb into the MessagesManager This change plugs the MessagesDynamoDb class into the live serving flow in MessagesManager. Tests are not yet as comprehensive for this big a change as they should be, but they now compile and pass so checkpointing here with a commit. * Put DynamoDB before RDBS when deleting specific messages * Extract method * Make aws sdk version into a property * Rename clientBuilder * Discard messages with no GUID * Unify batching logic into one function * Comment on the source of the value in this constant * Inline method * Variable name swizzle * Add timers to all public methods * Add missing return statements * Reject messages that are too large with response code 413 * Add configuration to control dynamo DB timeouts * Set server timestamp from the ReceiptSender * Change to shorter key names to optimize IOPS * Fix tests broken by changing column names * Fix broken copyright template output * Remove copyright template error text * Add experiments to control use of dynamo and rds in message storage * Specify instance profile credentials for the dynamic configuration manager * Use property for aws sdk version * Switch dynamo to instance profile credentials * Add metrics to the batch write loop * Use placeholders in logging		2021-02-03 10:03:19 -06:00
