kandi X-RAY | DBS Summary

DBS is a C++ library. DBS has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

C++ library implementing a dynamic bitset, that can store unlimited number of bits (restricted to number of values represented by size_t type). This library offers similar functionality to std :: bitset or boost :: dynamic_bitset, but is based on different design. Internally dbs is implemented as tree like structure, which allows for representing sparse bitsets with low memory overhead. Bitset once created cannot be modified later, any operation on a bitset creates an independent copy. However only modified blocks are copied.

Yes, but you'll need to call Win32 function CreateProcess from a homemade program in C/C++. You can then have 32768 chars for your command line, but nothing guarantee you that java.exe can accept it.
Yes, use a for command within your batch.
Don't know, I didn't look at the Java code.

Normally, something like this should work: it would convert each file one at a time, but it will process all files automatically.

How do I design a table in Cassandra for a TinyURL use case?

Asked 2022-Mar-05 at 08:55

Recently I came across a well-known design problem. 'Tiny URL'

What I found was people vouching for NoSQL DBS such as DynamoDB or Cassandra. I've been reading about Cassandra for a couple of days, and I want to design my solution around this DB for this specific problem.

What would be the table definition? If I choose the following table definition:

Create table UrlMap(tiny_url text PRIMARY KEY, url text);

Wouldn't this result in a lot of partitions? since my partition key can take on around 68B values (using 6 char base64 strings)

Would that somehow affect the overall read/write performance? If so, what would be a better model to define the table.

...

Lot's of partitions is fine, think of it as using c* as a key value store.

I am not sure if you have seen this message in the portal when you created the account/also mentioned in the doc

"You will not be able to switch between the backup policies after the account has been created"

since you need to select either "Periodic" or "Continuous" at the creation of Cosmos Account, it becomes mandatory.

Update:

You will not see the above in portal anymore, you can Switch from "Periodic" to "Continous" on an existing account and that cannot be reverted. You can read more here.

GORM - Golang Change Database at Runtime

In the UI you can select different options in a dropdown, which relate to data held in different databases. I have created models for the data, and as the table schemas are the same between the DBs, I would like to simply switch between the DBs according to which option the user has selected.

How can this be achieved in GORM 2.0? I would prefer to avoid specifying the "database.tableName" in the queries, as I have frequently used the

AWS Glue (Spark) very slow

Asked 2022-Jan-31 at 07:27

I've inherited some code that runs incredibly slowly on AWS Glue.

Within the job it creates a number of dynamic frames that are then joined using spark.sql. Tables are read from a MySQL and Postgres db and then Glue is used to join them together to finally write another table back to Postgres.

Example (note dbs etc have been renamed and simplified as I can't paste my actual code directly)

Generally, when reading/writing data in spark using JDBC drivers, the common issue is that the operations aren't parallelized. Here are some optimizations you might want to try:

Specify parallelism on read

From the code you provided it seems that all the tables data is read using one query and one spark executor.

If you use spark dataframe reader directly, you can set options partitionColumn, lowerBound, upperBound, fetchSize to read multiple partitions in parallel using multiple workers, as described in the docs. Example:

QUESTION

MySQL: Migrating Tables to a new DB - foreign keys

Asked 2022-Jan-28 at 17:00

I learned yesterday (via the magic of Google) that I can have foreign key references on values in another database. (MySQL InnoDB foreign key between different databases) I have two projects (currently set up in one database) and I'd like to move them into 3 databases: 1 for each project, and 1 for admin and user information (which is shared by both projects). I'd like to do this to make any future migration easier

My question is: Is it possible to move my admin tables from the current database into a new db, copying its data and automatically updating the foreign keys in my project dbs? The question on auto-updating foreign keys is really question I am seeking an answer on... Is there a way to do this in SQL (or some other way)?
