Method Detail

delete

reactor.core.publisher.Mono<Void> delete(String libraryName)

Deletes library. Error is thrown if library doesn't exist.

Parameters:

libraryName - library name

dump

reactor.core.publisher.Mono<byte[]> dump()

Returns serialized state of all libraries.

Returns:

serialized state

flush

reactor.core.publisher.Mono<Void> flush()

Deletes all libraries.

kill

reactor.core.publisher.Mono<Void> kill()

Kills currently executed functions. Applied only to functions which don't modify data.

list

reactor.core.publisher.Mono<List<FunctionLibrary>> list()

Returns information about libraries and functions per each.

Returns:

list of libraries

list

reactor.core.publisher.Mono<List<FunctionLibrary>> list(String namePattern)

Returns information about libraries and functions per each by name pattern.

Supported glob-style patterns: h?llo matches hello, hallo and hxllo h*llo matches hllo and heeeello h[ae]llo matches hello and hallo, but not hillo

Parameters:

namePattern - name pattern

Returns:

list of libraries

load

reactor.core.publisher.Mono<Void> load(String libraryName,
                                       String code)

Loads a library. Error is thrown if library already exists.

Parameters:

libraryName - library name

code - function code

loadAndReplace

reactor.core.publisher.Mono<Void> loadAndReplace(String libraryName,
                                                 String code)

Loads a library and overwrites existing library.

Parameters:

libraryName - library name

code - function code

restore

reactor.core.publisher.Mono<Void> restore(byte[] payload)

Restores libraries using their state returned by dump() method. Restored libraries are appended to the existing libraries and throws error in case of collision.

Parameters:

payload - serialized state

restoreAndReplace

reactor.core.publisher.Mono<Void> restoreAndReplace(byte[] payload)

Restores libraries using their state returned by dump() method. Restored libraries are appended to the existing libraries.

Parameters:

payload - serialized state

restoreAfterFlush

reactor.core.publisher.Mono<Void> restoreAfterFlush(byte[] payload)

Restores libraries using their state returned by dump() method. Deletes all existing libraries before restoring.

Parameters:

payload - serialized state

stats

reactor.core.publisher.Mono<FunctionStats> stats()

Returns information about currently running Redis function and available execution engines.

Returns:

function information

call

<R> reactor.core.publisher.Mono<R> call(String key,
                                        FunctionMode mode,
