SPLIT Lucene INDEX

[vishky]

Hi everyone
I have been tasked to look into split the Lucene Index. currently entire alfresco is in a single Lucene Index mount point.

1.Is it possible to have  two lucene index according to my logical folder in alfresco.

2. would there be a drastic effect on the performance if we split my lucene index Noew my lucene index size is approx. 50 GB

Sounds like you should upgrade.   What version of alfresco are you using?

we are using Alfresco 4.0 and our alfresco performance is very slow. we are only 250 files able to upload in 1 hour

I don't think you can split your lucene index in two.   If you do that then you will have problems combining the two results.   Perhaps your best bet will be to work out how to improve your existing index.   There will probably be stuff you don't need or stuff you can tune.   However that will probably require a reindex which may be painful at that size.

Another approach will be to upgrade to 5.0.  But I'd hold off for 5.1 which is due in a couple of weeks.  5.1 has beefed up sharding, as well as being much faster generally.
