FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package chunky
Chunky
A small library for dynamic chunking of large operations against an external system, like a database.
A 'chunk' is a unit of work with a target execution time. If each chunk in an iteration begins to take more time than the target to process, the size of future chunks is reduced.
This library also includes utilities for monitoring slave lag on a set of Doctrine2 connections, and can pause chunk processing to wait for replication to catch up. This sort of strategy is taken by tools like pt-online-schema-change in order to complete a process as fast as possible, but without impacting systems under production load.
Usage
Basic Usage
Options
- int
min: The minimum chunk size to ever return (default 2 * initial estimate) - int
max: The maximum estimated size to ever return (default 0.01 * initial estimate) - float
smoothing: The exponential smoothing factor, 0 < s < 1 (default 0.3)
Monitoring Replication Lag
A Chunk class is provided for monitoring MySQL slave lag on a set of slave
database servers: ReplicatedChunk. This class is MySQL-specific (because getting
the current slave lag is not implemented for other drivers).
Options
- int
max_lag: When replication lag reaches this many seconds, the slave is considered lagged - int
pause: The number of microseconds to pause for when slave lag is detected (before rechecking lag) - int
max_pause: The total number of microseconds the chunk will pause for before continuing or throwing an exception - boolean
continue: Whether to continue ifmax_pauseis reached; default is to throw an exception and not continue
Installation
This library can be loaded yourself with PSR4, but you'd usually just install it with
Composer. The package name is vend/chunky.
