    I have a query that you might be able to solve I am saving data from Kafka to timescaleDB But for each offset mesages I need to query db to get userId associated with IOT sensor. So for each offset processing one query is executed. Causing max connection error. Any solution for that (for now I added redis + connection pooling) but I don't think it will solve it for the long term 2. As data grows to 30-40gb of the single table inserts get slower in timescaleDB what should we do to make it fast

    • @anirvandecodes
      @anirvandecodes 18 วันที่ผ่านมา

      There are a few configuration changes you can do Batching: Set linger.ms (5-50 ms) and increase batch.size (32-128 KB). Serialization: Opt for efficient formats like Avro or Protobuf. Partitions & Proximity: Add more partitions and deploy near Kafka brokers. In production people generally use more scalable solutions than just a Python producer app, Check out this : docs.confluent.io/platform/current/connect/index.html Do share the playlist with your LinkedIn community.

I am loading from Excel into postgres and generating a hashed column, every time a new record, or updated record a new hash key is generated for that column. I am trying to do an incremental update. Here is the select stmnt SELECT id, "name", alternate_name, description, email, website, tax_status, tax_id, year_incorporated, legal_status, logo, uri, parent_organization_id, hashed_value FROM organization; My CDC is based on hashed_column. Lets say name is changed in excel, when i load the data into postgres i get a new hashed key for the hashed_value column and similarly for a new record. How do i do my incremental load? any suggestion

      that concept is called as change data feed , you need to first find out the records which have changed , There are different techniques , like in sql you can do SELECT * FROM table1 EXCEPT SELECT * FROM table2 to find what rows have changes then only insert those records.
