The 7 Most Popular Time Series Data Formats

Are you tired of dealing with messy, unstructured time series data? Do you want to make sense of your data and extract valuable insights? Look no further! In this article, we will explore the 7 most popular time series data formats that will help you organize and analyze your data efficiently.

What is a Time Series Data Format?

Before we dive into the different formats, let's first define what a time series data format is. A time series data format is a way of structuring data that contains a timestamp and a corresponding value. This type of data is commonly used in fields such as finance, healthcare, and IoT, where data is collected over time and analyzed for trends and patterns.

1. CSV (Comma Separated Values)

CSV is one of the most popular file formats for time series data. It is a simple and lightweight format that can be easily imported into most data analysis tools. CSV files contain rows of data, where each row represents a timestamp and its corresponding value. The timestamp is usually in a standard format such as ISO 8601.

timestamp,value
2021-01-01T00:00:00Z,10
2021-01-01T00:01:00Z,15
2021-01-01T00:02:00Z,20

2. JSON (JavaScript Object Notation)

JSON is another popular format for time series data. It is a lightweight and flexible format that can be easily parsed by most programming languages. JSON files contain a list of objects, where each object represents a timestamp and its corresponding value.

[
  {"timestamp": "2021-01-01T00:00:00Z", "value": 10},
  {"timestamp": "2021-01-01T00:01:00Z", "value": 15},
  {"timestamp": "2021-01-01T00:02:00Z", "value": 20}
]

3. InfluxDB Line Protocol

InfluxDB is a popular time series database that uses its own data format called InfluxDB Line Protocol. This format is designed to be highly efficient and optimized for storing and querying time series data. InfluxDB Line Protocol uses a simple syntax where each line represents a timestamp and its corresponding value.

measurement,tag1=value1,tag2=value2 value=10 1609459200
measurement,tag1=value1,tag2=value2 value=15 1609459260
measurement,tag1=value1,tag2=value2 value=20 1609459320

4. Apache Avro

Apache Avro is a data serialization system that is commonly used for time series data. Avro uses a compact binary format that is designed to be fast and efficient. Avro files contain a schema that defines the structure of the data, which makes it easy to read and write data in different programming languages.

{
  "type": "record",
  "name": "SensorData",
  "fields": [
    {"name": "timestamp", "type": "string"},
    {"name": "value", "type": "int"}
  ]
}

5. Apache Parquet

Apache Parquet is a columnar storage format that is commonly used for time series data. Parquet is designed to be highly efficient and optimized for querying large datasets. Parquet files contain metadata that describes the structure of the data, which makes it easy to read and write data in different programming languages.

timestamp (string) value (int)
2021-01-01T00:00:00Z 10
2021-01-01T00:01:00Z 15
2021-01-01T00:02:00Z 20

6. Apache ORC

Apache ORC is another columnar storage format that is commonly used for time series data. ORC is designed to be highly efficient and optimized for querying large datasets. ORC files contain metadata that describes the structure of the data, which makes it easy to read and write data in different programming languages.

timestamp (string) value (int)
2021-01-01T00:00:00Z 10
2021-01-01T00:01:00Z 15
2021-01-01T00:02:00Z 20

7. Protocol Buffers

Protocol Buffers is a data serialization system that is commonly used for time series data. Protobuf uses a compact binary format that is designed to be fast and efficient. Protobuf files contain a schema that defines the structure of the data, which makes it easy to read and write data in different programming languages.

syntax = "proto3";

message SensorData {
  string timestamp = 1;
  int32 value = 2;
}

Conclusion

In conclusion, there are many different time series data formats to choose from, each with its own advantages and disadvantages. CSV and JSON are simple and widely supported, while InfluxDB Line Protocol, Apache Avro, Apache Parquet, Apache ORC, and Protocol Buffers are optimized for storing and querying large datasets. The choice of format ultimately depends on your specific use case and requirements.
