To effectively increase the hit ratio on the local data cache in Snowflake, employing a combination of strategies can be beneficial. One method involves seeding the cache with queries. By executing frequently used queries, the data needed for those queries gets stored in the cache, enhancing access times and improving performance for subsequent executions of the same queries. This process ensures that common data is readily available, reducing the need to fetch data from the main storage.

Increasing the cluster size also plays a critical role in improving the hit ratio. A larger cluster can handle more concurrent workloads, which can lead to increased data being loaded into the cache. As more data is processed, especially for larger datasets or more complex queries, there is a higher likelihood that relevant data remains in the cache for longer periods.

Additionally, altering the data cache memory parameter can result in a larger cache size, which expands the amount of data that can be stored locally. With more memory allocated, the system can retain a greater volume of frequently accessed data, thereby boosting the hit ratio.

Combining these techniques—seeding the cache, increasing cluster size, and adjusting memory parameters—collectively enhance the efficiency of the local data cache, leading to improved performance in data retrieval and processing tasks. Thus, acknowledging all
