Multiple nodes not working in tCouchbaseDCPInput component

KKlimczuk1618309742 — Sat, 16 Nov 2024 00:02:31 GMT

Hello,

Documentation says that bootstrap nodes field should contain addresses separated with commas: "enter the names or IPs of these nodes in this field, separating them using commas (,)" (https://help.talend.com/r/l3v7SecP0krCnE_GeFyYNw/CSnEsOOSjhP9ljKXhvdq9w).

I tried to insert multiple addresses: "IP, IP, IP" or "IP",

"IP", "IP" - results: Could not connect to cluser or Could not parse field. The only way to make job working is to insert only one node but how can I be certain that data will be collected from all nodes?

Am I doing something wrong or there is a bug in tCouchbaseDCPInput component?

Hello,

Does it work well when you are connecting to cluster by using tCouchbaseInput component?

Could you please show us your tCouchbaseDCPInput component setting screenshot here?

Best regards

It works with both components, with dcp component it only work when I provide single node address. And my question is how can I be certain that it connect all 3 of my nodes?

I configure them this way (address and bucket name is dummy data):

I have additional question which can solve my problem other way. Is it possible to use tCouchbaseInput component can receive whole document in json? Now I have to specify columns which I want to load from document database, is there any solution to load whole document in some "value" column?

Hello,

We are supposing that there might be a problem with dcp connection if you are able to use multiple addresses in tCouchbaseInput component.

As I don't have an environment for testing now, could you please open an issue under Talend DI component project on our bugtracker for our R&D team to investigate it further?

Best regards

I have error on that page.

Could you refer to my second question? Is there any possibillity to receive whole document in json (not only certain columns) from couchbase using tCouchbaseInput (not using n1ql)?

Hello,

It seems to be a new feature to pull the entire couch base document via tCouchbaseInput component . Is it possible for you to do a query like SELECT *?

Best regards

Nodes dont have query service installed and it cant be changed, so every N1QL is not an option. I have also checked loading documents by views but I cant find option for view in tCouchbaseInput. So SELECT * ... cant be done in my case, but maybe it can be done with view - could you help me how to do this with view?

Hi,

In a similar situation i am taking the nodes from the couchbase server section and putting them in bootstrap nodes for tcouchbasedcpinput component with ".."

Kindly mention the format as am getting runtime exception that it could not connect to cluster or bucket.

I do not have tcouchbaseinput as am using talend 7.3 version.

Thanks.
