azure cosmosDb "mongorestore" failes with "Request size is too large"

Question

I try to migrate my mongoDb to azure´s cosmosdb. when I try to do the import as following

mongorestore --host $host:10255 -u $user -p $password --ssl --sslAllowInvalidCertificates --batchSize 240 --drop --db chronas-api $folderPath

I get this error:

error: Message: {"Errors":["Request size is too large"]}

I have tried already some other values for the --batchSize param but nothing worked.

can someone help me to workaround this issue?

@NickChapsas Is there a workaround for bigger than 2MB collections? — nauti, May 09 '18 at 21:09
The limit is not about the collection but the individual document — Nick Chapsas, May 09 '18 at 21:18
I have a document bigger than 2mb. so that means its not possible and I can not use cosmosdb? — aumanjoa, May 10 '18 at 19:46

Since you have already tired to try to reduce the number of import documents each batch, I think you need to make sure that per document is less than 2MB. The maximum size for a document is 2MB based on the official statement.

Hope it helps you.

@aumanjoa Unfortunately, the limitation can not be bypassed so far. – Jay Gong May 11 '18 at 01:36
@aumanjoa If you adopt the answer, you could mark it for others' reference on the forum.Thx. – Jay Gong May 17 '18 at 01:17
@aumanjoa You can, of course, break it up and then use some background job to process them. – avinava basu Dec 13 '19 at 11:49
