connect.s3.kcql=INSERT INTO $bucket:prefix SELECT * FROM kafka_topic PARTITIONBY _header.date, _header.time

Partitioning by Year, Month, Day, and Hour

This scenario partitions data by year, month, day, and hour. It utilizes a transformation process to insert record timestamp headers, enabling partitioning based on these time components.

transforms=partition
transforms.partition.type=io.lenses.connect.smt.header.InsertRecordTimestampHeaders
transforms.partition.date.format="'data_date='yyyy-MM-dd"
transforms.partition.hour.format="'hour='HH"
connect.s3.kcql=INSERT INTO $bucket:prefix SELECT * FROM kafka_topic PARTITIONBY _header.date, _header.hour

Partitioning by Date and Hour

This scenario partitions data by date and hour, using record timestamp headers for partitioning based on these time components.

transforms=partition
transforms.partition.type=io.lenses.connect.smt.header.InsertRecordTimestampHeaders
transforms.partition.date.format="'dt='yyyy-MM-dd"
transforms.partition.hour.format="'hour='HH"
connect.s3.kcql=INSERT INTO $bucket:prefix SELECT * FROM kafka_topic PARTITIONBY _header.date, _header.hour

Partitioning by Raw Creation Date

Data is partitioned based on the raw creation date, employing record timestamp headers for this partitioning scheme.

#"‘raw_cre_dt’=YYYY’-‘MM’-‘dd"

transforms=partition
transforms.partition.type=io.lenses.connect.smt.header.InsertRecordTimestampHeaders
transforms.partition.date.format="'raw_cre_dt='yyyy-MM-dd"
connect.s3.kcql=INSERT INTO $bucket:prefix SELECT * FROM kafka_topic PARTITIONBY _header.date

Partitioning by Creation Timestamp

Data is partitioned based on the creation timestamp, utilizing record timestamp headers for this partitioning scheme.

#"‘creation-ts’=YYYY-MM-dd"

transforms=partition
transforms.partition.type=io.lenses.connect.smt.header.InsertRecordTimestampHeaders
transforms.partition.date.format="'creation-ts='yyyy-MM-dd"
connect.s3.kcql=INSERT INTO $bucket:prefix SELECT * FROM kafka_topic PARTITIONBY _header.date

Partitioning by Created At Date

This scenario partitions data by the created at date, employing record timestamp headers for partitioning.

#"‘createdAt’=YYYY’-‘MM’-‘dd"

transforms=partition
transforms.partition.type=io.lenses.connect.smt.header.InsertRecordTimestampHeaders
transforms.partition.date.format="'createdAt='yyyy-MM-dd"
connect.s3.kcql=INSERT INTO $bucket:prefix SELECT * FROM kafka_topic PARTITIONBY _header.date

Partitioning by Created At Date (Alternate Format)

Similar to the previous scenario, this partitions data by the created at date, utilizing record timestamp headers for partitioning.

transforms=partition
transforms.partition.type=io.lenses.connect.smt.header.InsertRecordTimestampHeaders
transforms.partition.date.format="'createdAt='yyyyMMddHH"
connect.s3.kcql=INSERT INTO $bucket:prefix SELECT * FROM kafka_topic PARTITIONBY _header.date

transforms=partition
transforms.partition.type=io.lenses.connect.smt.header.InsertRecordTimestampHeaders
transforms.partition.date.format="'created_at='yyyy-MM-dd"
connect.s3.kcql=INSERT INTO $bucket:prefix SELECT * FROM kafka_topic PARTITIONBY _header.date

transforms=partition
transforms.partition.type=io.lenses.connect.smt.header.InsertRecordTimestampHeaders
transforms.partition.date.format="'date_hour='yyyy-MM-dd-HH"
connect.s3.kcql=INSERT INTO $bucket:prefix SELECT * FROM kafka_topic PARTITIONBY _header.date

transforms=partition
transforms.partition.type=io.lenses.connect.smt.header.InsertRecordTimestampHeaders
transforms.partition.date.format="'data_date='yyyy-MM-dd-HH"
connect.s3.kcql=INSERT INTO $bucket:prefix SELECT * FROM kafka_topic PARTITIONBY _header.date

Partitioning by Date and Hour

Data is partitioned based on the date and hour, employing record timestamp headers for this partitioning scheme.

transforms=partition
transforms.partition.type=io.lenses.connect.smt.header.InsertRecordTimestampHeaders
transforms.partition.date.format="yyyy-MM-dd-HH"
connect.s3.kcql=INSERT INTO $bucket:prefix SELECT * FROM kafka_topic PARTITIONBY _header.date STORE AS X

Default Confluent Partitioning

The default Confluent partitioning scheme follows the structure <prefix>/<topic>/<encodedPartition>/<topic>+<kafkaPartition>+<startOffset>.<format>. This provides a default partitioning mechanism for Kafka topics.

<prefix>/<topic>/<encodedPartition>/<topic>+<kafkaPartition>+<startOffset>.<format>
