What is the default size of 'max_binlog_cache_size' system variable?

Solution (By Examveda Team)

This question is asking about the 'max_binlog_cache_size' system variable in MySQL. This variable controls how much memory is used to store binary log events before they are written to disk.

Let's break it down:
* Binary Logs: Think of binary logs as a record of all the changes made to your MySQL database. They are very important for things like replication and data recovery.
* 'max_binlog_cache_size': This variable determines the maximum amount of memory (in bytes) that MySQL will use to hold these binary log events before flushing them to disk.

Now, let's look at the answer options:
* Option A: 1 GB * Option B: 2 GB * Option C: 4 GB * Option D: 8 GB
The default value for 'max_binlog_cache_size' is actually 32KB. This is a relatively small amount of memory, but it's usually enough for most databases. If you have a very busy database with lots of writes, you might need to increase this value.

So, the correct answer is None of the above because the default value is not listed in the given options.
