apache-flink - 如何在Flink中设置RocksDBStateBackend参数？

final StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment(); RocksDBStateBackend rocksDBBackEnd = new RocksDBStateBackend("file:///Users/zsh/tmp/rocksdb"); rocksDBBackEnd.setOptions(new OptionsFactory() { @Override public DBOptions createDBOptions(DBOptions currentOptions) { return currentOptions; } @Override public ColumnFamilyOptions createColumnOptions(ColumnFamilyOptions currentOptions) { final long blockCacheSize = 8 * 1024 * 1024; final long blockSize = 4 * 1024; final long targetFileSize = 2 * 1024 * 1024; final long writeBufferSize = 64 * 1024 * 1024; final int writeBufferNum = 1; //default 2 final int minBufferToMerge = 1; //default 2 return currentOptions .setCompactionStyle(CompactionStyle.LEVEL) .setTargetFileSizeBase(targetFileSize) .setWriteBufferSize(writeBufferSize) .setMaxWriteBufferNumber(writeBufferNum) .setMinWriteBufferNumberToMerge(minBufferToMerge) .setTableFormatConfig( new BlockBasedTableConfig() .setBlockCacheSize(blockCacheSize) .setBlockSize(blockSize) ); } }); env.setStateBackend(rocksDBBackEnd); .... env.execute();
