@quinthar Pardon me for asking a trivial question. I tried creating the SecureDB.cpp as suggested that is needed in this logic (I hope I located it in the right location)
if (SStartsWith(upperQuery, "INSERT ")) {
if(peer->params["Permafollower"] == "true") {
STHROW("400 Unauthorized");
} else
response["lastInsertRowID"] = SToStr(db.getLastInsertRowID());
}
... but sadly, am having trouble getting the code to understand "peer" variable
I tried this
Peer* peer = getPeerByID(command.initiatingPeerID);
(and I included some .h files at the top of the code)
This is in the BedrockPlugin_DB::processCommand(...) function but does not compile (that is how I came to know about "peer" variable) .
My C++ is quite rusty and I have not fully gone thru the code -- just kind of intuitively understanding what is to be done.
Hi all, I currently run a Discord bot with a SQLite backend database. It was working fine until I enabled sharding, meaning there are multiple threads writing/reading from the same SQLite database. I've enabled WAL mode however I still get SQLITE_BUSY error codes.
I stumbled upon Bedrock, so I figured I could give it a shot. I was able to build and run Bedrock successfully, pointing to my existing SQLite file, however, because there's no Java SDK for Bedrock I decided to give the MySQL plugin a shot. This is where the horror story starts, I'm only able to make SQL queries by connecting to Bedrock via the MySQL CLI client, but not if I'm connected via my bot using the ORM.
Am I out of luck here?
I hope this channel can help me: I just created Expensify/Bedrock#788
The tests pass and it is running, but it doesn't seem to matter what I send on 8888, I get no response. Any advice?
$ nc localhost 8888
SELECT 1;
Query: SELECT 1;
Query:
SELECT 1;All with no response
/var/log/syslog to see if any errors are being output? Also, what is the exact command line you are running?

Hello there, I am just starting with Bedrock Jobs and have some questions, I hope this is the right place?
I want my consumers to wait up to 30s for any Job thats with "hello.", so I send this request:
GetJob
name: hello.*
connection: wait
timeout: 30000But this command immediately returns a "404 No job found". Shouldn't it wait 30s before returning?
- can bedrockdb assign priority value dynamically?
- What needs to happen if nodes need to be added to the cluster at a later point in time?
- Is the data for designed to be ephemeral? Or should you always keep the data dir as fresh as possible and not rely on backups when/if a reboot of a node happens?
Connection: wait is currently not working. I believe we broke it when adding some multi-threaded optimizations, and hasn't been rebuilt yet. Is that right @tylerkaraszewski ?
would hope to be able to completely lose the .db file for a particular node when/if a crash happens on an instances or a VM needs a reboot (and be able to easily restore from s3 using an initContainer before starting bedrockdb).
Ah we do have a method to bootstrap from a S3 backup and then catch up, but we haven't automated it to the level you are likely thinking (ie, it doesn't identify the most recent backup and download it automatically). I could imagine you adding this without too much effort however. (I'm not 100% sure if our backup code is open source now that I think about it, we could look into this if you were seriously interested.)
the last question is about priority and whether or not one can be assigned dynamically on startup? So if i have a startup script that assigns a random integer as the priority are there any drawbacks to that?
Yes, that could likely work fine. In practice we find it makes the system easier to manage if the priorities are static, as then you have a better sense of which nodes are doing which without needing to consult the logs.
