|
* PlainTable now supports a new key encoding: for keys of the same prefix, the prefix is only written once. It can be enabled through encoding_type paramter of NewPlainTableFactory()
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
* Add AdaptiveTableFactory, which is used to convert from a DB of PlainTable to BlockBasedTabe, or vise versa. It can be created using NewAdaptiveTableFactory()

|
|
|

|
* Add two paramters to NewHashLinkListRepFactory() for logging on too many entries in a hash bucket when flushing
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
* Added new option BlockBasedTableOptions::hash_index_allow_collision. When enabled, prefix hash index for block-based table will not store prefix and allow hash collision, reducing memory consumption
