一、已完成

1. write()

write函数有很多接口，主要的适配目标包括：以Point的形式，以String字符串的形式将数据写入数据库中。

已经实现的接口有：

/**
 * Write a single Point to the default database.
 */
public void write(final Point point);

/**
 * Write a set of Points to the default database with the string records.
 */
public void write(final String records);

/**
 * Write a set of Points to the default database with the list of string records.]]
 */
public void write(final List<String> records);

/**
 * Write a single Point to the database.
 */
public void write(final String database, final String retentionPolicy, final Point point);

/**
 * Write a single Point to the database through UDP.
 */
public void write(final int udpPort, final Point point);

/**
 * Write a set of Points to the influxdb database with the new lineprotocol.
 */
public void write(final BatchPoints batchPoints);

/**
 * Write a set of Points to the influxdb database with the new lineprotocol.
 *
 * If batching is enabled with appropriate {@code BatchOptions} settings
 * ({@code BatchOptions.bufferLimit} greater than {@code BatchOptions.actions})
 * This method will try to retry in case of some recoverable errors.
 * Otherwise it just works as {@link #write(BatchPoints)}
 */
public void writeWithRetry(final BatchPoints batchPoints);

/**
 * Write a set of Points to the influxdb database with the string records.
 */
public void write(final String database, final String retentionPolicy,
                  final ConsistencyLevel consistency, final String records);

/**
 * Write a set of Points to the influxdb database with the string records.
 */
public void write(final String database, final String retentionPolicy,
        final ConsistencyLevel consistency, final TimeUnit precision, final String records);

/**
 * Write a set of Points to the influxdb database with the list of string records.
 */
public void write(final String database, final String retentionPolicy,
                  final ConsistencyLevel consistency, final List<String> records);

/**
 * Write a set of Points to the influxdb database with the list of string records.
 */
public void write(final String database, final String retentionPolicy,
        final ConsistencyLevel consistency, final TimeUnit precision, final List<String> records);

/**
 * Write a set of Points to the influxdb database with the string records through UDP.
 */
public void write(final int udpPort, final String records);

/**
 * Write a set of Points to the influxdb database with the list of string records through UDP.
 */
public void write(final int udpPort, final List<String> records);

2. ping()

/**
 * Ping this influxDB.
 */
public Pong ping();

3. version()

/**
 * Return the version of the connected influxDB Server.
 */
public String version();

4. flush()

/**
 * Send any buffered points to InfluxDB. This method is synchronous and will block while all pending points are
 * written.
 */
public void flush();

5. close()

/**
 * close thread for asynchronous batch write and UDP socket to release resources if need.
 */
public void close();

6. setDatabase()

/**
 * Set the database which is used for writing points.
 */
public InfluxDB setDatabase(final String database);

二、进行中

1. query()

query函数有很多接口，主要的适配目标包括：支持常规过滤、值过滤和tag过滤。同时支持聚合函数，选择函数等等功能。

已经实现的接口有：

/**
 * Execute a query against a database.
 */
public QueryResult query(final Query query);

/**
 * Execute a query against a database.
 */
public void query(final Query query, final Consumer<QueryResult> onSuccess, final Consumer<Throwable> onFailure);

/**
 * Execute a streaming query against a database.
 */
public void query(Query query, int chunkSize, Consumer<QueryResult> onNext);

/**
 * Execute a streaming query against a database.
 */
public void query(Query query, int chunkSize, BiConsumer<Cancellable, QueryResult> onNext);

/**
 * Execute a streaming query against a database.
 */
public void query(Query query, int chunkSize, Consumer<QueryResult> onNext, Runnable onComplete);

/**
 * Execute a streaming query against a database.
 */
public void query(Query query, int chunkSize, BiConsumer<Cancellable, QueryResult> onNext, Runnable onComplete);

/**
 * Execute a streaming query against a database.
 */
public void query(Query query, int chunkSize, BiConsumer<Cancellable, QueryResult> onNext, Runnable onComplete,
                  Consumer<Throwable> onFailure);

/**
 * Execute a query against a database.
 */
public QueryResult query(final Query query, TimeUnit timeUnit);
