> Cache is often used for frequently querying hot data. In data
synchronization read scenarios, data is usually queried only once. Is it
effective to configure cache-related settings in this case? Looking forward to
your reply.
You are right. In the case of synchronous data, it only needs to be queried
once, so I set the default value of `cache_blocks` to false. The default
cache_blocks value of Hbase Scan is True. At the same time, I am not sure
whether any user will use cache_blocks = true, so I set the cache_blocks
parameter to an optional parameter for special cases.
```
public static final Option<Boolean> HBASE_CACHE_BLOCKS_CONFIG =
Options.key("cache_blocks")
.booleanType()
.defaultValue(false)
.withDescription(
"When it is false, data blocks are not cached. When it is true, data blocks
are cached. This value should be set to false when scanning a large amount of
data to reduce memory consumption. The default value is false");
```
