Hi Luca,
It is still not clear can the different classes be located at the same
cluster ? As of v2.1.16 seems like this is impossible :
....
*create database plocal:/opt/orientdb/databases/db1 root root_pass;*
*create cluster clust1;*
*create class class1 extends V cluster clust1;*
*create class class2 extends V cluster clust1; *<=== error
*Error: com.orientechnologies.orient.core.exception.OSchemaException: Class*
*class2 already exists in current database*
Grouping several classes in the same cluster is impossible, but we can *remove
all the clusters from the class* !
*orientdb {db=db1}> info class class2*
*CLASS 'class2'*
*Super classes........: [V]*
*Default cluster......: class2 (id=12)*
*Supported clusters...: class2(12) *
*Cluster selection....: round-robin*
*Oversize.............: 0.0*
*orientdb {db=db1}> info class class2*
*orientdb {db=db1}> alter class class2 removecluster class2;*
*Class updated successfully*
*orientdb {db=db1}> info class class2*
*CLASS 'class2'*
*Super classes........: [V]*
*Default cluster......: null (id=-1)*
*Supported clusters...: *
*Cluster selection....: round-robin*
*Oversize.............: 0.0*
*orientdb {db=db1}> *
Is this behavior expected ? If yes - can somebody explain the logic behind
it ?
I'd like to have some classes located inside the same cluster. Is it
possible ?
TIA
