How to write HIVE data to Amazon S3 from DynamoDB?
Date:2023-02-18
1. If you want to write data from DynamoDB to Amazon S3 using Hive, you'll first need to set up an Amazon S3 endpoint in Hadoop. This can be done by setting up a Cloudera enterprise data hub with S3 integration.
2. After setting up the S3 endpoint, you'll need to set up a DynamoDB source and destination, in addition to a Hive database. This will link all three components together.
3. Next, you'll need to prepare your data for ingest. This can be done by creating an external table in Hive that points to your DynamoDB table, and loading the data into that external table.
4. Finally, you can create an external table in Hive that points to the S3 bucket and run an INSERT query to write the data from the DynamoDB external table into the S3 table.

How has accounting evolved over thousands of years?
Accounting has evolved substantially over the course of thousands of years. The very first instances of accounting date back to ancient Mesopotamia, where it was used to keep records of items being exchanged in bartering and trading transactions. Over time, the development of written language provided the opportunity to more accurately record and store such information, making it possible to more effectively track profits and losses as well as inventory. Throughout the ages, technological advancements in computers and calculators have enabled more accurate and detailed recording of accounting information, making it easier to identify discrepancies and errors in reports. Furthermore, auditing measures have been implemented in order to ensure accuracy and compliance. In recent years, countries around the world have adopted formal accounting standards and regulations, such as Generally Accepted Accounting Principles (GAAP) and International Financial Reporting Standards (IFRS).
