Hello everyone! I have a question about variable pipelines_batches_metadata_to_keep. I read in the document that this variable limits the number of pipeline batches in the information_schema.pipelines_batches table. It defaults to 1000. But when I count distinct from this table, I see that the number of batches is much larger (about more than 10,000 batches). Am I understanding this variable correctly? 1 post - 1 participant Read full topic ..read more

Hi I’m reading your documentation and it’s clear that I can choose to prewarm data (Local and Unlimited Database Storage Concepts · SingleStore Documentation) or prematurely execute my query to make sure that the data is fetched from unlimited storage and put onto the local disk. However, I’m looking for the opposite. How do I evict from the local disk/cache, if I know I’m not going to be needing the data that’s been pulled for the near future? I acknowledge it might be a weird request, but we’re seeing performance hits due to fetching data in some occasions when we’ve had to ingest a large bu ..read more

Hey folks, I’ve been working on a deployment script both for internal use, and as a public project to help folks installing SingleStore. Currently I’ve gone through the setup of installing it through the UI, but I’d like to automate that. Right now I only use 1 master aggregator and 1 leaf, what commands would need to be ran to install it locally instead? Thanks 2 posts - 2 participants Read full topic ..read more

Hey guys. I’ve created the following procedure: DELIMITER // CREATE OR REPLACE PROCEDURE updateColumnModelName(tableName TEXT, columnName TEXT) AS DECLARE has_column INT DEFAULT 0; DECLARE command TEXT; BEGIN SELECT EXISTS ( SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = tableName AND COLUMN_NAME = columnName ) INTO has_column; IF has_column THEN SET command = CONCAT('ALTER TABLE ', table_name, ' ADD COLUMN ', column_name, ' LONGTEXT CHARACTER SET utf8mb4 NOT NULL'); ELSE SET command = CONCAT('ALTER TABLE ', table_name ..read more

I have a memsql ciab cluster I use for local development. I’ve used the latest instructions to spin up this cluster from github page docker run -i --init \ --name memsql-ciab \ -e SINGLESTORE_LICENSE=$MEMSQL_LICENSE_KEY \ -e ROOT_PASSWORD=singlestore_doesnt_work \ -p 3306:3306 -p 8080:8080 \ --platform linux/amd64 \ ghcr.io/singlestore-labs/singlestoredb-dev:latest The cluster is healthy when there are no queries running. The moment I run a query, I start getting these errors. uncategorized SQLException for SQL [SELECT col1, col2, col3, DOT_PRODUCT(vector, JSON_ARRAY ..read more

We are observing something strange with our leaf node memory utilization. We have a database with a couple schemas on it, each containing some data. We see “TOTAL MEMORY USAGE” of around 15GB of memory in Studio. We then create a new schema. We do not populate the new schema with any data at all. It has a fair number of tables (about 1,000) but Studio shows only 9MB for memory usage in the Databases view. However, we see the “TOTAL MEMORY USAGE” goes up to around 19GB of memory in Studio when we add this schema. Dropping the schema reclaims the memory. What are we doing wrong that causes so mu ..read more

As per docs: There’s unlimited storage access available for SingleStore in Standard edition. How can this be used? When I try to attach an unlimited storage, it asks me to get premium license. 1 post - 1 participant Read full topic ..read more

Hello everyone! I have a question that what memory (RAM) of master aggregator stores and how can i manage them? Typically my Singlestore cluster uses very little memory from the master aggregator. But because of some error it increased very high and I couldn’t release it even after restarting MA. Thank you in advance. 1 post - 1 participant Read full topic ..read more
