QUESTION
I'm working on a project where I need to migrate from Postgres to MongoDB. The issue is, I cannot save the entire Postgres database to memory. Also, unlike approaches taken here or here, this is not a one-time migration, so I can't copy the entire contents of the Postgres database as text on disk every time data is transferred between the databases.
I was wondering if there was some way to "stream" data, row by row, from Postgres into MongoDB--realy, frompsycopg2
to pymongo
.
edit: I suppose I should make the question more specific; I'm asking whether there exists a python library that can stream data between SQL/NoSQL databases, preferably one that works well with psycopg2
and pymongo
.
edit2 For those who plan on down-voting, could you leave a comment explaining why? I thought it was a pretty legitimate question.

Answered 2018-Dec-22 at 07:38To anyone else looking for a solution, I found a python library that might help. This Stack Overflow post asked a similar question to mine, but the author was looking for node.js or java libraries for migration from Postgres to Mongo. However, one of the respondents linked to this python library: pg2mongo: A hassle-free postresql to mongo migration framework.
