Sailesh KrishnamurthyGUEST
At the same time, there was also recollection that if you look at ads, it's very different from Google Search or Photos and so on and so forth.
Sailesh KrishnamurthyGUEST
By the way, some of these consumer services that run on Spanner, you can look at the DDL file, like the sets of tables, and you can stare at it and make sense of it, fifteen tables, twenty tables.
Sailesh KrishnamurthyGUEST
But you look at ads, it's a classic enterprise application, thousands and thousands and thousands of tables, and not just one, many, many applications.
Sailesh KrishnamurthyGUEST
So if you would look at the ad system, you needed the scale of s- that was there in Google, but you also needed the functionality of enterprise applications.

Sailesh KrishnamurthyGUEST
You could have your data in a relational schema.
Sailesh KrishnamurthyGUEST
You can build an overlay on top of it.
Sailesh KrishnamurthyGUEST
You have a DDL command that says create property graph, and you just...
Sailesh KrishnamurthyGUEST
You don't actually move the data.
FredHOST
And
DougHOST
he made... amazing movie for how he fucking did it like you're not watching this movie thinking you're gonna get fucking interstellar or not the revenant or any DDL movie
FredHOST
DSL dick sucking lips hell yeah no you're right though he nailed exactly what he was going for yeah and I It depends.
FredHOST
What did those people go in thinking it was? Did they read and think it was a Lovecraftian monster that's taking over a restaurant? And they're like, what the fuck? This is infomercials the whole time.
Artificial IntelligenceNARRATOR
cTunnel's schema evolution capabilities allow data synchronization to account for changes in data structures rather than simply moving the data itself.
Artificial IntelligenceNARRATOR
Through mechanisms such as schema mapping, DDL propagation, dynamic application, and compatibility checks, schema changes can become part of the pipeline's runtime processing rather than an unexpected source of failure.
Artificial IntelligenceNARRATOR
This is particularly important for CDC workloads.
Artificial IntelligenceNARRATOR
When the schema of a source database table changes, a data synchronization system cannot simply assume that the schema will remain unchanged forever.
Steve JonesHOST
SQL history and SQL prompt saves me often, right? I can't remember what code I ran, but it doesn't capture results.
Steve JonesHOST
And if I'm running scripts, whether it's DDL or DML, or I'm clicking in SSMS, I would like a record.
Steve JonesHOST
I do try to not click things in SSMS in production and instead use the script button to copy-save those scripts and then run them.
Steve JonesHOST
It's a better habit, but in a crisis, I know I might forget, as would others.
CornHOST
It's just going to look different.
CornHOST
Fewer people writing DDL by hand.
CornHOST
More people looking at AI output and saying, no, this join will be slow at scale.
CornHOST
This column type is wrong.
Jeffrey PalermoHOST
But for the database, what does that look like? Because people are used to, if they have access to inspect production versus UAT or non-production instance, and they're connecting to different instances.
Jeffrey PalermoHOST
But then at the same time, you have a Git repository where maybe your database project is in the source of all the DDL and other...
Jeffrey PalermoHOST
So... what does that look like for, for databases? In fact, you have multiple databases and then what's the, what's the production version of the skill versus somebody just made a change to the skill and development, but we haven't had, you know, haven't promoted that yet.
Jeffrey PalermoHOST
Can you illustrate that for us?
Artificial IntelligenceNARRATOR
So far, you cannot fully trust code written by agents, so a human needs to review it.
Artificial IntelligenceNARRATOR
Agents are also not very helpful with databases and data operations, DDL.
Artificial IntelligenceNARRATOR
You can see it if you try asking an agent to change the type of a column in Atwo Terabyte Database.
Artificial IntelligenceNARRATOR
So these issues we'll have to solve together.
