DAX support

[cbjjensen]

How can we configure this to use DAX Client ? https://aws.amazon.com/dynamodb/dax/

https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/clients/client-dax/index.html

since this is just a wrapper of dynamoose, please make feature request over there.

@hardyscc this is not so much a feature request as much as it is a question about how to configure nestjs-dynamoose to use dax. dynamoose does support dax configuration, but I am unsure how to pass in configuration into nestjs-dynamoose for it to use dax.

Note the parameter here found in this pr: https://github.com/dynamoose/dynamoose/pull/330/files#diff-2eb2746547ba4e5403ca09626c2b38f2d201f4e3a0cb5ab97567030c48366acd

As well as this : https://v1.dynamoosejs.com/api/config/#dynamoosesetdocumentclientdocumentclient

sample usage of dax: https://github.com/dynamoose/dynamoose/issues/764#issuecomment-759924968

const AmazonDaxClient = require('amazon-dax-client');
const dax = new AmazonDaxClient({endpoints: [endpoint], region: region});

const dynamoose = require("dynamoose");
dynamoose.aws.ddb.set(dax);

@cbjjensen

could you help to try if this work or not?

import AmazonDaxClient from 'amazon-dax-client';
...

DynamooseModule.forRoot({
  ddb: new AmazonDaxClient({endpoints: [endpoint], region: region}) as any,
}),

@Module({
  imports: [
    ConfigModule.forRoot({ envFilePath: '.env' }),
    DynamooseModule.forRoot({
      logger: false,
      // aws: {
      //   region: process.env.AWS_REGION,
      //   accessKeyId: process.env.AWS_ACCESS_KEY,
      //   secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
      // },
      ddb: new AmazonDaxClient({
        endpoints: [
          'daxs://dax-franchise-new.rvgqtq.dax-clusters.ap-northeast-1.amazonaws.com',
        ],
        region: process.env.AWS_REGION,
      }) as any,
      table: {
        // create: true,
        // waitForActive: false,
        initialize: false,
        // update: false,
        // tableClass: TableClass.standard,
        // throughput: 'ON_DEMAND',
        // prefix:
        //   process.env.NODE_ENV !== 'dev' ? `${process.env.NODE_ENV}-` : '',
      },
    }),
  ],
  providers: [transactionBase],
  exports: [transactionBase],
})
export class DynamodbModule {}

I config like this, but if key initialize = false it'll throw error "Table category has not been initialized." if key initialize = true, i can't start source because DAX throw error

node_modules/amazon-dax-client/src/AmazonDaxClient.js:158 throw new DaxClientError('createTable is not support for DAX. Use AWS.DynamoDB instead.', DaxErrorCode.Validation, false);

I really stuck in here. please help

[hardyscc]

@cbjjensen did you try table: { create: false } ?

[ThienNDDi]

@hardyscc Yes i did. when i call any server, they threw error because it does not find table i can not set table: { create: true } because DAX not support create table in dynamodb

[hardyscc]

please refer to https://github.com/hardyscc/aws-nestjs-starter how to create table using serverless see https://github.com/hardyscc/aws-nestjs-starter/blob/master/resource/dynamodb.yml and here is how to generate this file https://github.com/hardyscc/aws-nestjs-starter/blob/master/genres.ts

[ThienNDDi]

@hardyscc I'm using cdk and create table in aws, and i sure that the table already exist in dynamodb but seem dax can not found the table. I confuse and unknown the reason why, because there is non error has been thrown

[hardyscc]

@cbjjensen I think you should get help from dynamoose, since this is just a wrapper of it.

[ThienNDDi]

@hardyscc Sadly, i asked Charlie Fish. And he confirmed dax not work in dynamoose V3
