|
* host1|host2|... - generates set of replicas from host1, host2, ...
|
|
* abc{8..10}def - generates set of shards abc8def, abc9def, abc10def.
|
|
* abc{08..10}def - generates set of shards abc08def, abc09def, abc10def.
|
|
* abc{x,yy,z}def - generates set of shards abcxdef, abcyydef, abczdef.

|
* abc{x|yy|z} def - generates set of replicas abcxdef, abcyydef, abczdef.

* abc{1..9}de{f,g,h} - is a direct product, 27 shards.
