You can check the lag on the read replica by running: select pg_current_wal_lsn() on the primary ( db.bit.io) and select pg_last_wal_receive_lsn() on the replica ( ) at the same time and comparing the LSNs. Your reads must be always and exactly up-to-date - If you need to be perfectly up-to-date, you must directly connect to the primary as necessary.However, there are several situations in which bit.io's configuration of read replicas are not appropriate or have tradeoffs: In most cases, read replicas are a strict benefit - they reduce latency and increase throughput. With bit.io serverless, the major benefit is reduced latency because bit.io automatically scales up your primary as load increases. Generally, read replicas are best used to either (1) reduce latency on reads or (2) remove load from your primary. Troubleshooting Common Connection Issues.Python-psycopg2 and the bit.io Python SDK.
