Hi All,
Firstly, thanks for your contribution to this bravo project. And I see a tips below about sstCacheSize.
So, Should I avoid to use sstCacheSize feature ?
/**
*

!!! This option is experimental !!!

*
* Set the size of the Shared Strings Table cache. This option exists to accommodate
* extremely large workbooks with millions of unique strings. Normally the SST is entirely
* loaded into memory, but with large workbooks with high cardinality (i.e., very few
* duplicate values) the SST may not fit entirely into memory.
*

* By default, the entire SST will be loaded into memory. Setting a value greater than
* 0 for this option will only cache up to this many entries in memory. However,
* enabling this option at all will have some noticeable performance degredation as you are
* trading memory for disk space.
*
* @param sstCacheSize size of SST cache
* @return reference to current {@code Builder}
*/
public Builder sstCacheSize(int sstCacheSize) {
this.sstCacheSize = sstCacheSize;
return this;
}
