[??????o.--]

Thanks you for help??Your explanation is very helpful to me. I will put forward 
this description in github later. Hope that more users can understand the

????:&nbsp;????: I have a question when deploying Rocketmq Ledger



  
Hi,
 
&nbsp;
 
First of all, thanks for using RocketMQ. Hope the following answers could solve 
your confusions:
 
&nbsp;
 
 1.&nbsp;&nbsp;&nbsp;  The "Dledger fast setup??DLedger??????????"  part 
introduced the way while you would like to quick-start or test the DLedger mode 
of RocketMQ locally. In other words, fast-try.sh will launch the nodes within 
three different processes on your local machine (as you could see in the doc, 
the addresses of  those three nodes are the same but have different ports). 
This is available for the developers who have the needs of debugging or trying 
DLedger mode efficiently.
 
 For the ??DLedger Cluster setup (DLedger????????)?? part, it is for someone 
who wants to build the cluster of RocketMQ  running DLedger mode in production 
environment (different machines) if the cluster requires the fail-over ability 
provided by Raft.
 
&nbsp;
 
In brief conclusion, the first part is for someone who wants to quick-try the 
DLedger mode locally, and the second part is for someone  who would like to run 
RocketMQ with DLedger mode in the actual production environment (e.g., in 
RocketMQ cluster).
 
&nbsp;
 
 2.&nbsp;&nbsp;&nbsp;  Of course, you could run the second step independently 
without downloading the source release of DLedger project since the RocketMQ 
project has already  involved the DLedger dependency in the library.
 
&nbsp;
 
 3.&nbsp;&nbsp;  Those three files are the configuration for you to 
quick-launch the nodes locally. It is more likely for the testing purpose. I 
guess the doc just want  to show how to get the DLedger project and build it, 
but it seems like there is no need for installing it separately. This might be 
a problem of our documentation, which you are welcome to propose a GitHub issue 
for it.
 
&nbsp;
 
&nbsp;
 
Best regards,

 ????: I have a question when deploying Rocketmq Ledger
 
  
hello??
 
  
When setting up the Rocketmq ledger, there are two methods introduced on the 
official website,  one is "Dledger fast setting up??Dledger??????????", 
 
the other is "Dledger cluster setting up??Dledger??????????". 
 
The first one needs to download and package the source code of the ledger, and 
the second one  does not. My question is: 1: What are the differences between 
the two? Are they the same? 2: If only the second step is followed, is it 
feasible not to download the source code of the Dledger??  3??What is the 
purpose of installing the ledger? I took a look at bin/dimmer/fast try sh??  
When you execute start all, you still use three configuration files.
