Whether an unsuspecting developer simply assumes a DELETE FROM parent_table WHERE id=3 will at most delete one row, down to surprising behavior such as in REPLACE INTO queries, which actually run an implicit DELETE, leading to mass destruction of data. What seemed like a simple transaction now turns into a massive operation, that involves excessive locking, increased MVCC overhead, impact on replication lag, and more.īut perhaps the greatest danger is the potential unexpected loss of data. You intend to DELETE a single row, but end up deleting hundreds, thousands, or more, rows in multiple tables. ON DELETE CASCADE is a risky and resource-consuming action. This operation runs recursively for all of a parent's children, as well as for their children, should they also employ ON DELETE CASCADE. If you DELETE a row from a parent table, any referencing rows in a child table are subsequently deleted within the same transaction. This is the most greedy, or ambitious action type. The discussion is relevant to ON UPDATE constraints, as well.įoreign keys further support three types of action (illustrated below for ON DELETE): ON DELETE CASCADE In this document, we discuss ON DELETE as it is the more impactful of the two. It lives within the child's table space.įOREIGN KEY constraints are available for row deletion ( ON DELETE) and row updates ( ON UPDATE). A FOREIGN KEY constraint isn't a separate entity. In MySQL, foreign keys are only implemented by the storage engine layer, namely the default and popular InnoDB engine. This typically happens when you introduce functional partitioning/sharding and/or horizontal sharding. FOREIGN KEY constraints are difficult to maintain once your data grows and is split over multiple database servers. It is a more complex process involving more steps to refactor a schema containing foreign key constraints. As applications evolve, there is a need for schema refactoring.For example, it is impossible to change a column from INT to BIGINT, neither on a parent nor child table. Once two tables engage in a foreign key constraint relationship, it is not possible to change the data types for the columns used by the foreign key.Expect degraded performance, especially in high concurrency workloads. MySQL foreign keys introduce increased locking for data and metadata changes.There are a few significant technical reasons why we do not recommend foreign key constraints for some applications: Why does PlanetScale not recommend constraints? We'll soon cover an example of a schema with and without foreign key constraints to clarify this slight difference. We still encourage you to use the relational model and associate tables by "pointing" rows from one table to another with foreign keys, just not with the CONSTRAINT. However, if you still want to use them, we currently have beta support for foreign key constraints with minor limitations. A constraint also prevents the existence of "orphaned rows" in different methods, as you'll see described soon.Īt PlanetScale, we don't recommend using foreign key constraints. Namely, it ensures that a child table can only reference a parent table when the appropriate row exists in the parent table. A table can also refer to itself, as a special case.Ī FOREIGN KEY constraint is a database construct, an implementation that forces the foreign key relationship's integrity (referential integrity). A foreign key typically suggests how you should JOIN tables in most queries. A row in a "parent" table may be referenced by one or more rows in a "child" table. A foreign key is a logical association of rows between two tables, in a parent-child relationship.

This will add the closed captions in the SCC file to all of the target files in the batch. Under Additional Information, there is an option to choose a closed caption file. Select the batch first so it is highlighted, then go to the Inspector pane. Next, check and set your destination on the Destinations tab of the Settings pane.ĥ. For Quicktime outputs, Compressor adds the closed captions as a track in the Quicktime file, and you can use most versions of Quicktime, version 7.2 or later, to view both the video and the captions.Ĥ. For broadcast output formats like the MPEG-2 Program or Transport streams, Compressor will encode the captions into the video using the EIA-708 protocol. If you do not have a broadcast monitor for previewing the captioned output, you many want to create a proxy video using the same caption file and a more compressed Quicktime file. If you need other target formats you can add them to the batch in the same way. Drag the setting you want to use onto the batch on the project pane.ģ. You'll need to confirm with the stations or distribution networks that you are using the exact file format requirements, but you will find several common presets for broadcast under the MPEG Files section on the Settings pane. Next select the settings for your output files. Click Add File, select the source file, and it will appear as the starting point for a new batch.Ģ. Typically this will be an exported version of your final video in a ProRes or DNx codec. The first step is to add the source file to your batch. Select the version of the file that matches the time coding of your video source file. When you select this option you will receive two versions of the SCC file: one with drop frame time codes and one with non-dropframe (NDF) time codes. You can get the SCC file using our CaptionSync service, by selecting the Sonic Scenarist DVD Captions (. To use this method you will need two input files: a high-quality, final version of your video to use as the source file, and a time-coded caption file in SCC format. This tutorial walks you through the steps required to insert broadcast captions into a video using Apple Compressor and an SCC file from CaptionSync. Many high-end hardware and software solutions exist for this, but if you don’t have a large volume of files to process, Apple Compressor is a simple, fast, and inexpensive solution. The question then becomes how best to encode the closed captions into your video file. CaptionSync can provide captions in several output formats commonly used by broadcast producers, such as the Sonic Scenarist (SCC) format, which can then be used to encode closed captions into the final video files delivered to your station or distribution network. Many television and cable networks are phasing out tape submission in favor of file-based content delivery. You can download the encoded MPEG from our website (119.1 MB) (MPEG-2 Program Stream file encoded with captions using the process described in this article).
