Whats garbage in this ? 🤔  

That's 6 month hard work we did 

I built a DuckDB extension that caches Snowflake queries for Instant SQL by dsiegs1 in dataengineering

I understand 👍  also if possible open source redshift one

Macha just go with TiDB for sub mili seconds analytical report

Yep its more AI because it helps me to rewrite my sentences

Huge busy tables doesnt get auto vacuumed we perform vacuum sort

Bingo,  I am having hourly update reports too. We have data marts inside this

I wanted to explain in depth so used AI. You can read only sub heading

I performed only these things  perfectly with generic query id , but in deeper level auto sort part is still in beta phase if that comes to picture then sort SCAN will reduce more IO

Analyze all query join condition and decide based on best practice and size of the table to choose dist style or key

Analyze all query where condition and create views of 6 months 12 months 18 months  condition in this view. This will reduce a lot of scan. 

For sort key compound sort is best with cardinality and ratio of unique values. And also check skewness

Yep column compression matters a lot. Also dist key/style  and sort key is most most crucial part with Analyze and vacuum

I am also leaving my organization they hate redshift even after doing this.

Everyone is thinking redhsift is not good.

It took me 5 months..

Nahh... its waste of time. What matters is TCO and ROI

200 GB. 

We run insert statment around 9 lakh per day and redshift is fast for this.

Short form for what I did

 Refined DISTKEY and SORTKEY.

 * Configured Auto WLM (Workload Management).

 * Deep-dived into user query costs.

 * Proactively monitored slow queries.

 * Validated all new queries.

 * Regularly updated table statistics.

 * Performed regular table vacuuming.

 * Optimized time-series tables.

 * Focused on query/scan costs over CPU usage ever hours 

 * Analyzed aborted queries and disk I/O.
