I need a mongodb query something like
db.getCollection("xyz").find({"_id" : {$regex : {$in : [xxxx/*]}}})
My Use case is -- I have a list of Strings such as
[xyz/12/poi, abc/98/mnb, ytn/65/tdx, ...]
The ids that are there in the collection(test) are something like
xyz/12/poi/2019061304.
I will get the values like xyz/12/poi
from the input list, the other part of the id being yyyymmddhh
format.
So, I need to go to the collection and find all the documents matching the input list with the ID of the documents in the test collection.
I can retrieve the documents individually but that does not seem to be a feasible option as the size of the input list is more than 10000.
Can you guys suggest a more feasible solution. Thanks in advance.
I tried using $in with $regex. But it seems mongodb does not support that. I have also tried pattern matching but even that is not feasible for me. Can you please suggest an alternative to using $in with $regex in mongodb.
Expected result could be an aggragate query/a normal query so that we hit the database only once and get the desired output rather than hitting the db for 10000 odd times.
