that's pretty much how you do it, yeah

Tony Leung•2/22/24, 4:38 PM

sorry I'm pretty new with SQLite

MMax (@rozenmd)that's pretty much how you do it, yeah

Tony Leung•2/22/24, 4:39 PM

sorry to bother you

hope you don't mind

Max (@rozenmd)OP•2/22/24, 4:39 PM

that's alright i learned SQL via postgres myself

Max (@rozenmd)OP•2/22/24, 4:39 PM

https://sqlite.org/queryplanner.html is a very good guide btw

Tony Leung•2/22/24, 4:39 PM

I'm just curious that why the expression (tiktok_link IS NULL OR tiktok_link = '')(tiktok_link IS NULL OR tiktok_link = '') in index does not work like mysql

Tony Leung•2/22/24, 4:39 PM

can't seem to use it anywhere

Max (@rozenmd)OP•2/22/24, 4:40 PM

indexing by tiktok_linktiktok_link covers that anyway

Tony Leung•2/22/24, 4:40 PM

thanks, I was overthinking

Tony Leung•2/22/24, 4:41 PM

i does not work as expected... this is much different from mysql

Tony Leung•2/22/24, 4:42 PM

i was nuking sqlite all the time... thanks for your support

MMax (@rozenmd)indexing by `tiktok_link` covers that anyway

Tony Leung•2/22/24, 4:44 PM

btw does using indexed byindexed by reduces my rows read?

TTony Leung btw does using `indexed by` reduces my rows read?

Max (@rozenmd)OP•2/22/24, 4:53 PM

From what I understand of https://www.sqlite.org/lang_indexedby.html, only if the index you tell the query planner to use is more efficient

Max (@rozenmd)OP•2/22/24, 4:53 PM

It's not a hint, so it will ignore better indexes if you tell it indexed byindexed by

Tony Leung•2/22/24, 5:19 PM

thanks for clarification. I will check for rows read in d1 query meta

Advany•2/22/24, 6:07 PM

I have a array of 50k json objects. Is there any limit in d1 to insert that in one go?

And query those json objects, any limits on that?

Advany•2/22/24, 6:07 PM

I could not understand if this is limited during the beta

Tony Leung•2/22/24, 6:49 PM

thanks, indexing like above drastically reduced my rows read, from ~400 to 10. It turns out that I don't really need INDEXED BYINDEXED BY after all, sqlite is smart enough to choose the right index for me.

Tony Leung•2/22/24, 6:54 PM

so expression indexing does not help much for this situation (or does not work at all). I guess it's only needed when I have to query prefix match like ABC%ABC%

MMax (@rozenmd)can you try accessing the DB again?

Sej•2/23/24, 1:55 AM

Hi, I can now access the DB. Thanks for the help

that was quick, certified not :soontm: moment

Paul•2/23/24, 4:34 PM

I’m getting some pressure to move to Postgres so some people can use the admin dashboard tools like Looker. Any chance D1 works with any of those things?

Cyb3r-Jak3•2/23/24, 4:37 PM

Not unless they have added support for the HTTP API. D1 doesn’t have a standard connection string that others do

Isaac McFadyen•2/23/24, 4:56 PM

The same answer applies here. Power BI doesn't have a D1 connector so you're out of luck there, unfortunately.

Isaac McFadyen•2/23/24, 4:56 PM

You could write a Worker that proxies requests to D1 but I'm not sure how Power BI's support for raw HTTP requests for data is.

volcanicislander•2/23/24, 4:57 PM

I was thinking about this as a workaround. Power BI can import data through an API endpoint

Santosh•2/23/24, 5:55 PM

Is this not the reason that D1 cant compete with databases like Turso? I mean you would have to go via workers and a DO, which means theres a certain minimal latency. Is my understanding incorrect?

Santosh•2/23/24, 11:55 PM

Understood. But what I said is also correct as well? :lul:

Adi•2/24/24, 12:10 AM

Question about D1 bindings to Pages. I know that when you bind D1 to a worker it automatically restricts which region the worker spins up to be as close to D1 as possible.
Does it have the same behavior when you bind a pages project? If so, is there any way to get around that?

James•2/24/24, 4:17 AM

That behaviour only happens with smart placement, not by default

James•2/24/24, 4:17 AM

If you don’t want that behaviour, simply don’t enable smart placement

SSantosh Understood. But what I said is also correct as well? :lul:

Max (@rozenmd)OP•2/24/24, 8:18 AM

in theory if they had the same number of PoPs as us, and we had to go through Workers first and they didn't, yeah you'd gain 1-10ms of latency overhead on us

JJames That behaviour only happens with smart placement, not by default

Adi•2/24/24, 12:30 PM

ahh I see! That's great to hear. Thanks

Advany•2/24/24, 2:37 PM

I have a use case where I store a array of jsons and need to get them quickly for each customer.

I was thinking of storing that in a seperate table for each customer.

Is there a limit on amount of tables (or virtual tables) for d1?

Advany•2/24/24, 2:38 PM

And can will deletes and inserts (i dont do updates) of a table be automatically added to fts5 virtual table?

K•2/24/24, 6:09 PM

You can do separate db for each customer. Basically you can create unlimited number of d1 DBs. IIRC you can store only 100 tables in one db.

Also, how big are those arrays? There is a limit of 1MB per row so maybe could just store them in row-per-customer.

Advany•2/25/24, 6:42 AM

That could be a idea. Let me investigate that!

I need to query and full text search stuff inside those jsons. Thats why d1

Santosh•2/25/24, 7:29 AM

If it is 1 -10 ms latency, thats wonderful. Based on the earlier conversations we have had regarding about DO locations (where do DO live links), DO's are available only in a few DC (For example SGA for an Indian audience). And the minimal latency for DO location from MUmbai would be 200 ms according to the web site. I am making some assumptions here a. That the D1 replicas when they come into pic after Q1 would still live near SGA like locations due to colo reqs 2. Not just initial connections to DO, but subsequent latency for all communications would be the same. In that case, how can the latency be lower (like 10 ms) without smart placement? I would say having these many pops actually is a menace for performance as compared to bettering it. Anothe rpoint to ponder and I am thinking out aloud -> about a use case where I depend on an R2/KV and a DO ( i have such a use case) . I am going every where to collect my objects and the initial request would take multiple latency hits, I cache them using Cache API after the initial, but again theres no guarantee my next customer would hit the same pop.

that's pretty much how you do it, yeah
