Command line client for Amazon DynamoDB. V0.1.
Why? - primarily a tool to aid with updating throughputs on Amazon DynamoDB. Amazon DynamoDb allows throughput modification on the following basis:
- Throughput may be incremented by 100% on any one update
- Takes ~60 seconds for a throughput update to process
- Throughput may only be decremented twice in any 24 hour period
Whilst DynamoDB rocks, sometimes you need to adjust throughputs without having to mess about with the web interface. dynamocmd automates this process to save time and money!
npm install -g dynamocmd
dynamocmd -f <config file> [-r <region>] [-c <command>]
As per the AWS node.js SDK, the config file contains a json with the following elements:
{ "accessKeyId": "YOUR ACCESS KEY",
"secretAccessKey": "YOUR SECRET ACCESS KEY",
"region": "us-east-1"}
dynamocmd -c <config file>
Start dynamocmd in interactive mode. Available commands:
dynamo> help show interactive help
dynamo> list list all tables in for account in region
dynamo> describe <table name> describe the named table
dynamo> query <table name> <pkey> <range comparison> <rkey> run a query and return the first 20 results into the node repl, where:
<pkey>- primary key value<range comparison>- comparison operator one of IN, NULL, BETWEEN, LT, NOT_CONTAINS, EQ, GT, NOT_NULL, NE, LE, BEGINS_WITH, GE, CONTAINS<rkey>- range key value
dynamo> throughput <table name> <read> <write> set the table read and write throughputs
dynamo> exit to quit
dynamo> throughput mytable 2048 512 will set the table throughput values to 2048 read, 512 write.
dynamo> throughput mytable 1 1 Will set a table back to idle.
dynamo> query mytable 37025542720 LT 1362229748
Will run the query and return the first 20 elements back to the node repl variable data:
repl>data.Items.length
20
dynamocmd -f <config file> -c 'throughput mytable 2048 512'
Will set the table throughput to the specified values and exit.
