[jboss-jira] [JBoss JIRA] (AS7-6317) Uploaded File Replication in cluster
[
https://issues.jboss.org/browse/AS7-6317?page=com.atlassian.jira.plugin.s...
]
Paul Ferraro resolved AS7-6317.
-------------------------------
Resolution: Rejected
A replicated directory is the wrong solution. File systems do not have ACID
characteristics - rather a database or datagrid is the appropriate solution. The whole
point of a grid filesystem is to extend the available memory space to the collective heap
of an entire cluster. The grid would run on a separate and much larger set of nodes - not
the JBoss AS nodes themselves. If you don't need the performance of a data grid, then
a database is more appropriate.
If storing the large blobs in a replicated database results in too much network traffic -
using any kind of replication would seem to be equally bad. Rather, consider storing the
blobs in a dedicated database, using something as simple like HA-JDBC for
high-availability.
Uploaded File Replication in cluster
------------------------------------
Key: AS7-6317
URL: https://issues.jboss.org/browse/AS7-6317
Project: Application Server 7
Issue Type: Feature Request
Components: Clustering
Affects Versions: 7.0.2.Final
Environment: jboss-as-web-7.0.2.Final , Linux , Postgresql , Mod_cluster as Load
balancer
Reporter: hitesh yadav
Assignee: Paul Ferraro
Labels: jboss, synced
We are using jboss-as-web-7.0.2.Final with Linux , Postgresql , Mod_cluster as Load
balancer .
Our goal is to achieve 2 or 3 Node in cluster.
Using jboss-as-web-7.0.2.Final we get HttpSession replication + Cache Replication.
We want same thing for Uploaded file replication.
Meas when we upload image file or some other file in cluster it must have to replicate to
all node in cluster .
we d'nt want to store file in database b'coz of large size and we r using
database replication so it take lots of Network traffic.
We have look GridFilesystem but it store file in memory which is not acceptable due to
size of Heap .
We want some solution from JBOSS side that one or more directory in cluster sync with
each other .....so that any file uploaded in this Direcory all Node in Cluster get same
File.
In case, Node which handle client request crash then other Node must have knowledge to
handle request related with Uploaded File on previous Node.
