go-db-engine

ConfigDBDir - configures the DB directory location.

ConfigLogLevel - configures the log level of the database, default to WARN.

ConfigMemtableSizeByte - configures roughly how much data (in bytes) should be saved into the storage in memroy before it gets flushed into disk.

ConfigSStableDatablockSizeByte - configures how much data (in bytes) should be stored for each data block in the underlying sstable file.

ConfigWalStrictMode - configures if strict mode should be turned on or not for the wal (write-ahead-log).

NewBasicMemTable - create a new memtable instance TODO: (p3) make the memtable implementaion thread-safe.

NewBasicSSTableIndex - creates a new basic sstable index.

NewBasicSSTableReader - creates a new `SSTableReader` instance that handles reading data from sstable file.

NewBasicSSTableWriter - creates a new `SSTableWriter` instance along with newly created sstable file.

NewBasicWal - creates a new WAL instance and an underlying WAL file if `syncOnWrite` is set to true, each write operation will always be flushed to the storage device.

NewDatabase - creates a new database instance.

NewWalFile - creates a new WAL file with name "wal_<unix timestamp>" under `walDir` if `syncOnWrite` is set to true, each write operation will always be flushed to the storage device.

ReadDataWithVarintPrefix - read a varint prefixed data block into buf.

WriteDataWithVarintSizePrefix - writes data to w with a varint size prefix.

BasicSSTable - a basic implementation of the `SSTableReader` and `SSTableWriter` interface.

BasicSSTableIndex - a basic implementation of the `SSTableIndex` interface.

BasicWal - implements the `Wal` interface.

BasicWalLog - represents a WAL log record.

Database - something that you can write data to and read data from.

DBSetting - sepcifies the various configurations of the database that are customizable.

MemtableRecord - represents a single inserted record.

SkipListMemTable - A memtable implementation using the skip list data structure.

SSTableError - includes error for specifc sstable operation.

SSTableFileMetadata - metadata about sstable file.

WalError - wraps errors with WAL operation and basic information before the error happens.

MemTable - A memtable handles the in-memory operatoins of the DB on data that has not been persisted into the file system.

SSTableIndex - represents an index for a SSTable file.

SSTableReader - represents a reader that reads data from a sstable file.

SSTableWriter - represents a writer that dump content into a sstable file.

VarintSizePrefixDataReader - a reader interface for varint prefixed data.

Wal - represents a write-ahead-log.

WalFile - file interface that defines basic methods needed for WAL operations the interface can be satisfied by `os.File`.

DBConfig - configuration function for db setting.
