SPLITSHARD Working
Hi,
I need to SPLITSHARD such that one split remains on the same machine as
original and another uses new machines for leader and replicas. Is this
possible ? Please let me know what properties do I need to specify in
Collection API to achieve this.
Thank you,
Vrinda Davda

Vrinda,
The expected behavior if parent shard 'shardA' resides on node'1', node'2'
... node'n' and do a SPLITSHARD on it.
the child shards, shardA_0 and shardA_1 will reside on node'1', node'2' ...
node'n'.
shardA ------- node'1' (leader) & node'2' (replica)
after splitshard;
shardA ------- node'1' (leader) & node'2' (replica) (INACTIVE)
shardA_0 ------ node'1' & node'2' (ACTIVE)
shardA_1 ------ node'1' & node'2' (ACTIVE)
Any one of them can be a leader and replica for the children nodes.

Thanks I go it.
But I see that distribution of shards and replicas is not equal.
For Example in my case :
I had shard 1 and shard2 on Node 1 and their replica_1 and replica_2 on
Node 2.
I did SHARDSPLIT on shard1 to get shard1_0 and shard1_1 such that
and shard1_0_replica0 are created on Node 1 and shard1_0_replica1,
shard1_1_replica1 and shard1_1_replica0 on Node 2.
Is this expected behavior ?
Thank you,
Vrinda Davda

No, split always happens on the original node. But you can move the
sub-shard leader to a new node once the split is complete by using
AddReplica/DeleteReplica collection API.
