Hi everyone. I've been experiencing a very weird issue, and I hope someone could help me with it.
I've mapped a Redshift table using SQL Alchemy's ORM. Here is my code. from sqlalchemy.ext.automap import automap_base from sqlalchemy import Column, Integer, String, ForeignKey from sqlalchemy import create_engine from sqlalchemy.ext.declarative import declarative_base from sqlalchemy.orm import sessionmaker import psycopg2 user = "" passwd = "" host = "" engine = create_engine('postgresql+psycopg2://{}:{}{}'.format(user,passwd, host)) ######################################################################## Base = automap_base() class Bookmarks(Base): __tablename__ = 'my_table' __table_args__ = {"schema":"dev"} agent_id = Column(Integer, primary_key=True) username = Column(String) email = Column(String) first_name = Column(String) last_name = Column(String) role_id = Column(Integer) role = Column(String) team = Column(String) access_level = Column(String) location = Column(String) def loadSession(): """""" metadata = Base.metadata Session = sessionmaker(bind=engine) session = Session() return session Base.prepare() session = loadSession() res = session.query(Bookmarks).all() Everything works fine after executing the code. The problem is that it looks like it's been interacting weirdly with AWS. I've been creating tables to test this out, and it seems like everytime I map a Redshift table using this code, the table becomes totally unresponsive. I'm able to query it using SQLAlchemy, but if I try to alter it, or delete it, it will literally take a hour before getting a response. I'm not getting any errors, it's just that everything becomes very slow. The tables are very small, so this shouldn't be happening.
