Hi,

These are pre-compiled, tested for performance and are ingrained into the
system. So they can naturally be expected to be slightly faster than even
triggers. In the case of your question, why not use serial dat
This is probably the start of your quest into this project. No doubt you’ll
need to handle other queries.
So my suggestion is first to rationalise the data storage before digging any

Another option which is growing in popularity is distributed in memory cache.
There are quite a few companies providing such technology.
Pricing can range from free to quite expensive.
One recommendation with these technologies is to test them under heavy load

Good luck
The question to ask is what benefit would you gain by saving BLOB object on a

larger ones.
