# RocksDBLite
|
|
|
|
RocksDBLite is a project focused on mobile use cases, which don't need a lot of fancy things we've built for server workloads and they are very sensitive to binary size. For that reason, we added a compile flag ROCKSDB_LITE that comments out a lot of the nonessential code and keeps the binary lean.
|
|
|
|
Some examples of the features disabled by ROCKSDB_LITE:
|
|
* compiled-in support for LDB tool
|
|
* No backupable DB
|
|
* No support for replication (which we provide in form of TransactionalIterator)
|
|
* No advanced monitoring tools
|
|
* No special-purpose memtables that are highly optimized for specific use cases
|
|
* No Transactions
|
|
|
|
When adding a new big feature to RocksDB, please add ROCKSDB_LITE compile guard if:
|
|
* Nobody from mobile really needs your feature,
|
|
* Your feature is adding a lot of weight to the binary.
|
|
|
|
Don't add ROCKSDB_LITE compile guard if:
|
|
* It would introduce a lot of code complexity. Compile guards make code harder to read. It's a trade-off.
|
|
* Your feature is not adding a lot of weight.

If unsure, ask. :)
