Replica for MongoDB

[Sharath kumar M N]

I want to create a Mongo DB replica .this replica should be in sync
with Mysql(for every insert in Mysql it should reflect in Mongo DB)
and Solr interface (an index needs to be create in Lucene library of
Solr for every insert in Mongo DB).

i am dealing with tera bytes of data so I want to know the step by
step procedure to setup the above environment and time consumption for
the same.

Awaiting for your response.

Thanks in advance.

This entirely depends on how you plan on doing this.
Were you doing this in the app? Did you want a background process?

Hi

I want to setup the above environment in Linux server and it should be
a background process only.

Please suggest me on this at the earliest

Thank you.

This is really an architecture question for the app...
There are a number of ways of doing it with mongo.

Hi

can you please suggest one of the way at the earliset.

You can use something like this
(https://github.com/renctan/mongo-solr) to pick up changes for
mongodb.

As for the sql integration/replication I would suggest writing some
custom code to do the logical replication for your application.
Specifically I would either implement a trigger to log the records or
keep track of them with a date/timestamp so they can be easily found
and replicated. If you need more than replicate on insert (you have
mutable data) then you could use the same mechanism for them to update
data in mongodb.

I don't know any generic framework which is already written for this
as each action is pretty custom.
