This is to maintain the behavior before swithcing from InMemoryEnv to MockEnv

Partial implementation of the Env interface.

Note: memory_order_release must be sufficient

sets the internal key to be bigger or equal to all internal keys with this user key

Iterates over a vector of TestCases, keeping a running sum of the results of calling a given int-returning method on each. Returns the sum.

REQUIRED: Keys must be given to the function in sorted order (it expects the last key to be the largest).

Creates a new column family with the name columnFamilyName and allocates a ColumnFamilyHandle within an internal structure. The ColumnFamilyHandle is

@deprecated Instead use {@link AbstractNativeReference#close()}

<p>Returns the library name of the compression type identified by the enumeration value.</p> @return library name

Ok for uniqueness

<p>Returns currently set log level.</p> @return {@link org.rocksdb.InfoLogLevel} instance.

Support for iterating over the contents of a batch. @param handler A handler that is called back for each update present in the batch

Provides access to the event listener list.

Returns the current OS stack trace getter if it is not NULL; otherwise, creates an OsStackTraceGetter, makes it the current getter, and returns it.

What compression options for output

parse IEEE745 double precision: Significand precision length - 15 Maximum exponent value - 308 "If a decimal string with at most 15 significant digit

Append a blob of arbitrary size to the records in this batch. The blob will be stored in the transaction log but not in any other file. In particular,

Put a key inside a transaction

Use the specified filter policy to reduce disk reads. {@link org.rocksdb.Filter} should not be disposed before options instances using this filter is

The maximum number of write buffers that are built up in memory. The default is 2, so that when 1 write buffer is being flushed to storage, new writes

Use to control write rate of flush and compaction. Flush has higher priority than compaction. Rate limiting is disabled if nullptr. Default: nullptr
