purpose of this configuration item is that when the tablespace space is full, there is a need for the MySQL system to automatically expand how much space, each time the tablespace extension will let each SQL wait state. Increasing the auto-scaling size reduces the number of tablespace auto-expansions.3) Adjust the innodb_log_buffer_size configuration to 16M due to the default 1MThis configuration item sets the INNODB database engine to write log buff

For example, the design of the last demo is clear, because it is similar to the action in life, and the user knows the meaning of the action without any other prompts. Such interactions were of little use on non-touch screens, but they are of great significance to apps today.

initial buckets when the hash table was created, and the default build capacity is 16. You can also use a specific capacity.Size: The amount of data that is stored in the current hash table.Load factor: Load factor, default value of 0.75 (that is, 75%), expansion and re-hashing (rehash) if the value of size/capacity is greater than load factor when adding data to the hash table.Then, when the load factor is smaller than the child, the hash lookup performance increases, and the hash bucket space

number of primary shards can make subsequent expansions difficult. In reality, some techniques can make scaling easier when you need it.
All document APIs (,,,,, get index delete bulk update mget ) receive a routing parameter that is mapped to a shard from the definition document. Custom route values ensure that all related documents-such as documents belonging to the same person-are saved on the same shard. We'll explain why you need to do this

Finally, we would like to discuss the subquery unnested feature. In most cases, we think that Oracle can generate better execution plans. However, in practice, we have also found many such scenarios: The subquery speed is very fast and the data volume is small, but the speed is slow after the connection. The result is that the subquery in the execution plan is opened.
By default, Oracle has the "low computing" feature when estimating the number
