Summary
PreSplit and allocate the required chunks in a sharded cluster
Motivation
Who is the affected end user?
Developers who are trying to work in the sharded cluster environment
How does this affect the end user?
The developers are currently blocked and are using the sharded cluster without pre splitting.
How likely is it that this problem or use case will occur?
It occurs frequently.
If the problem does occur, what are the consequences and how severe are they?
Not able to presplit and create chunks in sharded cluster
Is this issue urgent?
Yeah
Database name : chasetest
Collection name: documents
Steps:
sh.disableBalancing("chasetest.documents")
sh.startBalancer();
sh.enableSharding("chasetest");
sh.shardCollection('chasetest.documents', {'SHARD_KEY':1})
for(x=0;x<840;x++) {
print(`sh.splitAt("chasetest.documents", { "SHARD_KEY": ${x} })`)
printjson(sh.splitAt("chasetest.documents", {"SHARD_KEY": x}))
}
