tks for replying.
"Some people narrow "scalable" to mean that you can horizontally scale it with active clustering. As you have read from the linked post, active clustering is a feature of the Alfresco Enterprise Edition, meaning it is not available in Alfresco Community Edition out of the box,unless you are considering third party extensions, e.g. like aldica."
So with third party extensions, e.g. like aldica, Community edition can also do application horizontal scale out, right?
But it is only for new alfresco, like 6.2 and 7 ?
"The database tier is also horizontally scalable, i.e. there are either vendor-provided variants or extensions to scale MySQL, MariaDB, or PostgreSQL. Alfresco Search Services (the index tier) also can be scaled horzontally by using Sharding - the main difference between Enterprise and Community Edition is that Community does not support dynamic shard registration."
but I have been told that the database tier of community edition 5.0 can't be clustered, like MySQL InnodB cluster, MariaDB cluste, PXC (Percona MySQL cluster), etc. so is that true ?
or starting from 6.2 the database tier can be clustered by MySQL, MariaDB or PXC?
"the main difference between Enterprise and Community Edition is that Community does not support dynamic shard registration"
and this also refers to Alfresco 6.2 - 7 ?
