How to extract data from ethereum using Talend

[YLi1644627156]

Very new to Talend. My very goal is to use Talend to do the following:

```

from web3 import Web3

w3 = Web3(Web3.HTTPProvider('https://mainnet.infura.io/v3/XXXXXXXXXXXXXXXXXXX'))

w3.eth.get_block('latest').items()

```

Wonder which components I need and how to achieve it.

Open to java implementation as well, if it is easier with tJava. 

Thanks

what is the data mapper component called? I have enterprise license.

Again I am not seeing tRestClient, how should I enable it?

The tRestClient component is standard in all Talend Studio products. It doesn't need to be enabled. If you type t r e s t c l i e n t into the design window you should see it. If you don't see it, you should contact support.

The Data Mapper is more than a single component. The component is called tHMap. But there are several configuration stages for this component. You should look at the documentation for this.
