BeginTxn starts a read-write transaction. All transactions should either be committed or aborted. If transactions are not released for long time it mi

Cleardeleted clear index node from deleted.

Cleardirty clear index node from dirty.

Clone mvcc instance and return the clone. Clone walks the entire tree and concurrent reads and writes will block until call returns.

CompactIndex will remove older versions of disk level snapshots and if merge is true, will merge all disk-levels into single level.

Dotdump to convert whole tree into dot script that can be visualized using graphviz. Until dotdump exits concurrent write operations will block.

Finalize will wait for read snapshot to catchup with the tip. To be careful when calling with background mutations, call may never return.

---- Exported Control methods ID of snapshot, same as name argument passed to OpenSnapshot.

Info return parameters used to build the snapshot and statistical information. mfile : m-index file name. zfiles : list of z-index file name

Key return current key under the cursor. Returned byte slice will be a reference to index-key, hence must not be used after transaction is commited or

LoadLLRB creates an LLRB instance and populate it with initial set of data (key, value) from iterator. After loading the data, applications shall use

LoadMVCC creates an MVCC instance and populate it with initial set of data (key, value) from iterator. After loading the data applications can use Set

Max return maximum value from sample.

Metadata return metadata blob associated with this snapshot.

Min return minimum value from sample.

Ones return the count of 1s in this 32-bit value.

PurgeIndex will purge all the disk level snapshots for index `name` founder under `diskpaths`.

PurgeSnapshot remove disk footprint of this snapshot.

SD return by how much the samples differ from the mean value of sample set.

Samples return total number of samples in the set.

Scan return a full table iterator, if iteration is stopped before reaching end of table (io.EOF), application should call iterator with fin as true. E

SetCAS a key, value pair in the index, if CAS is ZERO then key should not be present in the index, otherwise existing CAS should match the supplied CA

Setblack flag for llrb node.

Setdeleted mark index node as deleted. After marking it as deleted there is no going back.

Setdirty set index node dirty.

Setred flag for llrb node.

Stats return a map of histogram.

Utilization implement api.Mallocer{} interface.

Validate snapshot on disk. This is a costly call, use it only for testing and administration purpose.

Value return current value under the cursor. Returned byte slice will be a reference to value in index, hence must not be used after transaction is co

Valueref returns reference to value, if value is stored in separate file, else vpos will be -1.
