Column Families in MyRocks

In my webinar How To Rock with MyRocks I briefly mentioned the column families feature in MyRocks, that allows a fine tuning for indexes and primary keys.

Let’s review it in more detail.

To recap, MyRocks is based on the RocksDB library, which stores all data in [key => value] pairs, so when it translates to MySQL, all Primary Keys (data) and secondary keys (indexes) are stored in [ key => value ] pairs, which by default are assigned to “default” Column Family.

Each column family has individual set of

  • SST files, and their parameters
  • Memtable and its parameters
  • Bloom filters, and their parameters
  • Compression settings

There is a N:1 relation between tables and indexes to column family, so schematically it looks like this:

How do you assign …

Miami and Santo Domingo with MySQL Document Store

The next two weeks are a big change for me compared to the last two weeks.  The last two weeks I was in Belgium and now I am in Miami before heading to the Dominican Republic.  The one thing in common is that I am speaking on the MySQL Document Store.

SunshinePHP has become a favorite conference for many PHP developers for many reasons and this morning I will be running a three hour tutorial on using the PECL MySQL X DevAPI and the MySQL Document Store with PHP and then have a one hour talk later in the show. Plus I am joined by the amazing Kathy Forte who will speak on Driving Innovation With MySQL 8.0 and Docker.

MySQL Connector/Python 8.0.15: allow_local_infile Disabled by Default

Tweet

MySQL Server has a feature where you can insert data into a table from a file with the data delimited by commas, tabs, or another delimiter. This is particularly useful when you need to bulk import data, for example when restoring a backup or migrating data from one system to another including from another database product than MySQL. The mysqldump backup utility is an example of a program that supports exporting the data to delimited text files.

The statement to load the data is LOAD DATA INFILE. By default the file must be server-side and MySQL …

Percona Responds to MySQL LOCAL INFILE Security Issues

In this post, we’ll cover Percona’s thoughts about the current MySQL community discussion happening around MySQL LOCAL INFILE security issues.

This post is released given the already public discussion of this particular issue, with the exploitation code currently redacted to ensure forks of MySQL client libraries have sufficient time to implement their response strategies.

This post has been updated to now include previously redacted content, in line with responsible disclosure sufficient time has passed to allow forks to update and get those updates out for circulation.

Background

MySQL’s

LOCAL INFILE

  feature is fully documented by Oracle MySQL, and there is a legitimate use for the

MySQL to MongoDB - An Admin Cheat Sheet

Most software applications nowadays involve some dynamic data storage for extensive future reference in the application itself. We all know data is stored in a database which falls into two categories that are: Relational and Non-relational DBMS.

Your choice of selection from these two will fully depend on your data structure, amount of data involved, database performance and scalability.

Relational DBMS store data in tables in terms of rows such that they use Structured Querying Language (SQL) making them a good choice for applications involving several transactions. They include MySQL, SQLite, and PostgreSQL.

On the other hand, NoSQL DBMS such as …
