Build

First build static lib for RocksDB

cd rocksdb
USE_RTTI=1 DEBUG_LEVEL=0 make static_lib

Edge key layout

  • Different src/tgt
    • Forward [true, src_keys, null, tgt_keys]
    • Backward [false, src_keys, null, tgt_keys]
  • Same src/tgt
    • Forward [null, src_keys, true, tgt_keys]
    • Backward [null, src_keys, false, tgt_keys]

Isolation levels

  • Read uncommitted: write to the raw DB
  • Read committed: use transaction
  • Repeatable read: use snapshot
  • Serializable: do all reads with GetForUpdate
