# Performance Tuning

SQL is the most widely used language for data analytics. Flink's Table API and SQL enables users to define efficient stream analytics applications in less time and effort. Moreover, Flink Table API and SQL is effectively optimized, it integrates a lot of query optimizations and tuned operator implementations. But not all of the optimizations are enabled by default, so for some workloads, it is possible to improve performance by turning on some options.

In this page, we will introduce some useful optimization options and the internals of streaming aggregation which will bring great improvement in some cases.

{{< hint info >}}
The streaming aggregation optimizations mentioned in this page are all supported for [Group Aggregations]({{< ref "docs/dev/table/sql/queries/group-agg" >}}) and [Window TVF Aggregations]({{< ref "docs/dev/table/sql/queries/window-agg" >}}) now.
{{< /hint >}}

## MiniBatch Aggregation

By default, group aggregation operators process input records one by one, i.e., (1) read accumulator from state, (2) accumulate/retract record to the accumulator, (3) write accumulator back to state, (4) the next record will do the process again from (1). This processing pattern may increase the overhead of StateBackend (especially for RocksDB StateBackend).
Besides, data skew, which is very common in production, will worsen the problem and make it easy for the jobs to be under backpressure situations.

The core idea of mini-batch aggregation is caching a bundle of inputs in a buffer inside of the aggregation operator. When the bundle of inputs is triggered to process, only one operation per key to access state is needed. This can significantly reduce the state overhead and get a better throughput. However, this may increase some latency because it buffers some records instead of processing them in an instant. This is a trade-off between throughput and latency.

The following figure explains how the mini-batch aggregation reduces state operations.

{{< img src="/fig/table-streaming/minibatch_agg.png" width="50%" height="50%" >}}

MiniBatch optimization is disabled by default for group aggregation. In order to enable this optimization, you should set options `table.exec.mini-batch.enabled`, `table.exec.mini-batch.allow-latency` and `table.exec.mini-batch.size`. Please see [configuration]({{< ref "docs/dev/table/config" >}}#execution-options) page for more details.

{{< hint info >}}
MiniBatch optimization is always enabled for [Window TVF Aggregation]({{< ref "docs/dev/table/sql/queries/window-agg" >}}), regardless of the above configuration.
Window TVF aggregation buffer records in [managed memory]({{< ref "docs/deployment/memory/mem_setup_tm">}}#managed-memory) instead of JVM Heap, so there is no risk of overloading GC or OOM issues.
{{< /hint >}}

The following examples show how to enable these options.

{{< tabs "bfd23c92-3007-4ddd-a0df-9d42ac589faa" >}}
{{< tab "Java" >}}
```java
// instantiate table environment
TableEnvironment tEnv = ...

// access flink configuration
TableConfig configuration = tEnv.getConfig();
// set low-level key-value options
configuration.set("table.exec.mini-batch.enabled", "true"); // enable mini-batch optimization
configuration.set("table.exec.mini-batch.allow-latency", "5 s"); // use 5 seconds to buffer input records
configuration.set("table.exec.mini-batch.size", "5000"); // the maximum number of records can be buffered by each aggregate operator task
```
{{< /tab >}}
{{< tab "Scala" >}}
```scala
// instantiate table environment
val tEnv: TableEnvironment = ...

// access flink configuration
val configuration = tEnv.getConfig()
// set low-level key-value options
configuration.set("table.exec.mini-batch.enabled", "true") // enable mini-batch optimization
configuration.set("table.exec.mini-batch.allow-latency", "5 s") // use 5 seconds to buffer input records
configuration.set("table.exec.mini-batch.size", "5000") // the maximum number of records can be buffered by each aggregate operator task
```
{{< /tab >}}
{{< tab "Python" >}}
```python
# instantiate table environment
t_env = ...

# access flink configuration
configuration = t_env.get_config();
# set low-level key-value options
configuration.set("table.exec.mini-batch.enabled", "true"); # enable mini-batch optimization
configuration.set("table.exec.mini-batch.allow-latency", "5 s"); # use 5 seconds to buffer input records
configuration.set("table.exec.mini-batch.size", "5000"); # the maximum number of records can be buffered by each aggregate operator task
```

## Local-Global Aggregation

Local-Global is proposed to solve data skew problem by dividing a group aggregation into two stages, that is doing local aggregation in upstream firstly, and followed by global aggregation in downstream, which is similar to Combine + Reduce pattern in MapReduce. For example, considering the following SQL:

```sql
SELECT color, sum(id)
FROM T
GROUP BY color
```

It is possible that the records in the data stream are skewed, thus some instances of aggregation operator have to process much more records than others, which leads to hotspot.
The local aggregation can help to accumulate a certain amount of inputs which have the same key into a single accumulator. The global aggregation will only receive the reduced accumulators instead of large number of raw inputs.
This can significantly reduce the network shuffle and the cost of state access. The number of inputs accumulated by local aggregation every time is based on mini-batch interval. It means local-global aggregation depends on mini-batch optimization is enabled.

The following figure shows how the local-global aggregation improve performance.

{{< img src="/fig/table-streaming/local_agg.png" width="70%" height="70%" >}}

The following examples show how to enable the local-global aggregation.

{{< tabs "83f161de-8f58-472b-94e9-2e83975913bd" >}}
{{< tab "Java" >}}
```java
// instantiate table environment

// access flink configuration
TableConfig configuration = tEnv.getConfig();
// set low-level key-value options
configuration.set("table.exec.mini-batch.enabled", "true"); // local-global aggregation depends on mini-batch is enabled
configuration.set("table.exec.mini-batch.allow-latency", "5 s");
configuration.set("table.exec.mini-batch.size", "5000");
configuration.set("table.optimizer.agg-phase-strategy", "TWO_PHASE"); // enable two-phase, i.e. local-global aggregation
```
{{< /tab >}}
{{< tab "Scala" >}}
```scala
// instantiate table environment
val tEnv: TableEnvironment = ...

// access flink configuration
val configuration = tEnv.getConfig()
// set low-level key-value options

configuration.set("table.exec.mini-batch.allow-latency", "5 s")
configuration.set("table.exec.mini-batch.size", "5000")
configuration.set("table.optimizer.agg-phase-strategy", "TWO_PHASE") // enable two-phase, i.e. local-global aggregation
```
{{< /tab >}}
{{< tab "Python" >}}

configuration.set("table.optimizer.agg-phase-strategy", "TWO_PHASE"); # enable two-phase, i.e. local-global aggregation
```

## Split Distinct Aggregation

Local-Global optimization is effective to eliminate data skew for general aggregation, such as SUM, COUNT, MAX, MIN, AVG. But its performance is not satisfactory when dealing with distinct aggregation.

For example, if we want to analyse how many unique users logined today. We may have the following query:

```sql
SELECT day, COUNT(DISTINCT user_id)
FROM T
GROUP BY day
```

COUNT DISTINCT is not good at reducing records if the value of distinct key (i.e. user_id) is sparse. Even if local-global optimization is enabled, it doesn't help much. Because the accumulator still contain almost all the raw records, and the global aggregation will be the bottleneck (most of the heavy accumulators are processed by one task, i.e. on the same day).

The idea of this optimization is splitting distinct aggregation (e.g. `COUNT(DISTINCT col)`) into two levels. The first aggregation is shuffled by group key and an additional bucket key. The bucket key is calculated using `HASH_CODE(distinct_key) % BUCKET_NUM`. `BUCKET_NUM` is 1024 by default, and can be configured by `table.optimizer.distinct-agg.split.bucket-num` option.
The second aggregation is shuffled by the original group key, and use `SUM` to aggregate COUNT DISTINCT values from different buckets. Because the same distinct key will only be calculated in the same bucket, so the transformation is equivalent.
The bucket key plays the role of an additional group key to share the burden of hotspot in group key. The bucket key makes the job to be scalability to solve data-skew/hotspot in distinct aggregations.

After split distinct aggregate, the above query will be rewritten into the following query automatically:

```sql
SELECT day, SUM(cnt)
FROM (
    SELECT day, COUNT(DISTINCT user_id) as cnt
    FROM T
    GROUP BY day, MOD(HASH_CODE(user_id), 1024)
)
GROUP BY day
```

The following figure shows how the split distinct aggregation improve performance (assuming color represents days, and letter represents user_id).

{{< img src="/fig/table-streaming/distinct_split.png" width="70%" height="70%" >}}

NOTE: Above is the simplest example which can benefit from this optimization. Besides that, Flink supports to split more complex aggregation queries, for example, more than one distinct aggregates with different distinct key (e.g. `COUNT(DISTINCT a), SUM(DISTINCT b)`), works with other non-distinct aggregates (e.g. `SUM`, `MAX`, `MIN`, `COUNT`).

{{< hint info >}}
Currently, the split optimization doesn't support aggregations which contains user defined AggregateFunction.
{{< /hint >}}

The following examples show how to enable the split distinct aggregation optimization.

{{< tabs "d3608720-1d11-4cf9-a631-6c53a512d8c5" >}}
{{< tab "Java" >}}
```java
// instantiate table environment
TableEnvironment tEnv = ...

tEnv.getConfig()
  .set("table.optimizer.distinct-agg.split.enabled", "true");  // enable distinct agg split
```
{{< /tab >}}
{{< tab "Scala" >}}
```scala
// instantiate table environment
val tEnv: TableEnvironment = ...

tEnv.getConfig
  .set("table.optimizer.distinct-agg.split.enabled", "true")  // enable distinct agg split
```
{{< /tab >}}
{{< tab "Python" >}}
```python
# instantiate table environment
t_env = ...

t_env.get_config()
  .set("table.optimizer.distinct-agg.split.enabled", "true"); # enable distinct agg split
```
{{< /tab >}}
{{< /tabs >}}

## Use FILTER Modifier on Distinct Aggregates

In some cases, user may need to calculate the number of UV (unique visitor) from different dimensions, e.g. UV from Android, UV from iPhone, UV from Web and the total UV.
Many users will choose `CASE WHEN` to support this, for example:

```sql
SELECT
 day,
 COUNT(DISTINCT user_id) AS total_uv,
 COUNT(DISTINCT CASE WHEN flag IN ('android', 'iphone') THEN user_id ELSE NULL END) AS app_uv,
 COUNT(DISTINCT CASE WHEN flag IN ('wap', 'other') THEN user_id ELSE NULL END) AS web_uv
FROM T
GROUP BY day
```

However, it is recommended to use `FILTER` syntax instead of CASE WHEN in this case. Because `FILTER` is more compliant with the SQL standard and will get much more performance improvement.
`FILTER` is a modifier used on an aggregate function to limit the values used in an aggregation. Replace the above example with `FILTER` modifier as following:

```sql
SELECT
 day,
 COUNT(DISTINCT user_id) AS total_uv,
 COUNT(DISTINCT user_id) FILTER (WHERE flag IN ('android', 'iphone')) AS app_uv,
 COUNT(DISTINCT user_id) FILTER (WHERE flag IN ('wap', 'other')) AS web_uv
FROM T
GROUP BY day
```

Flink SQL optimizer can recognize the different filter arguments on the same distinct key. For example, in the above example, all the three COUNT DISTINCT are on `user_id` column.
Then Flink can use just one shared state instance instead of three state instances to reduce state access and state size. In some workloads, this can get significant performance improvements.

(NSFW), it is not welcome in this community. These descriptors are not
the sole limiting factors of what may be considered Illegal content, and
final discretion of what will be deemed as illegal content is reserved
exclusively to the moderation team. Content that promotes or incites
Violence

A Crypto-Currency can be a very emotion filled and polarizing topic to
discuss. Nevertheless, content that encourages or incites violence of
any kind will not be tolerated in any fashion. This includes content
that is of a violent nature directed towards any individual, or any
groups of people. Anything that violates this rule will result in
deletion of the violating content and a permanent ban of the violating
content poster. Content involving Bullying or Harassing Behavior
(Trolling)

This community, in the spirit of Crypto-Currency, is dedicated to open
and free discussion. However, bullying and harassment will not be
tolerated in any form on this platform. As a clarification, bullying or
harassing behavior is defined in this community as: systematic and/or
continued actions to torment or demean anyone in a way that would make a
reasonable person conclude that this community is not a safe platform to
express their ideas or participate in the conversation, or fear for
their safety or the safety of those around them. We choose to model our
communities attitude towards bullying and harassment in a similar
fashion to other community sites such as Reddit or Facebook.

Any content or behavior that violates this rule will result in deletion
of the violating content and a permanent ban of the violating content
poster. As a further clarification, being deliberately annoying or
participating in a heated discussion is not considered bullying or
harassment. However, there are healthy limits to all such behavior, and
any content or behavior that crosses this threshold will immediately be
considered a violation of this rule and will result in deletion of the
violating content and a permanent ban of the violating content poster.
This community does not support Trolling. Content that is of a Personal
or Private Nature (Doxxing)

This community will not tolerate or condone Doxxing. Period. Doxxing is
defined as: "The publishing of private or identifying information about
(a particular individual) on the Internet". A digital identity is not a
guarantee of privacy by any means, and this is a well known fact.

However, every individual is entitled to the privacy and security of
personal information that they have not chosen to divulge to the public.
Doxxing is an incredibly controversial subject. For clarification, if a
public figure, such as a CEO or well known entity has personally linked
a digital identity with their actual identity on a public forum or
community, posting information about such a link in a non-malicious
manner will not be defined as Doxxing.

This is a fine line to walk however, and all decisions in regards to
Doxxing will be left solely to the discretion of the moderators. While
discussions and debates can inflame tempers and leave lasting
impressions, revenge type posting such as Doxxing can do very real and
lasting damage to an individual's life. The moderation team of this
platform does not condone or tolerate Doxxing, and we ask that all users
do the same. Do not condone or encourage anyone to engage in or
participate in any Doxxing related content or activity.

Report all instances of Doxxing to a moderator immediately. Any content
or behavior that violates this rule will result in deletion of the

are not reputable and spam like. If your intention in joining this
community is to primarily post content of this scam / spam nature,
please take this content elsewhere.

If your presence in this community is to promote a certain good or
service, please contact the moderation team before you begin posting,
and express your intentions. Furthermore, please do not derail
conversations or debates with wildly off topic subjects or links.
Pushing a certain agenda or rhetoric dogmatically in contrast to the
overall tone of discussion is extremely spammy, and is not a welcome
addition to any dialogue.
