This page summarizes changes for Timeplus Enterprise and Timeplus Proton, on a biweekly basis, including new features and important bug fixes.

Nov 11, 2024​

Timeplus Proton v1.6.2​

  • Added a new EMIT policy in streaming SQL with global aggregation. The new EMIT PERIODIC .. REPEAT syntax will show the last aggregation result even there is no new event.
  • Fixed a bug that views with incorrect syntax could be created.

Timeplus Grafana plugin v2.0.0​

  • The new release of Timeplus Grafana Plugin v2.0, available now on our GitHub repository. This latest version introduces significant improvements in both performance and stability. Whether you’re using Timeplus Enterprise or the open-source Timeplus Proton, this plugin allows you to seamlessly monitor real-time data through Grafana, utilizing both simple and complex analytics to track live data trends.

Documentation Updates​

  • Updated the guide of Ingest REST API to add more instructions for self-hosting Timeplus Enterprise. API keys are only available in Timeplus Cloud. For self-hosting deployment, please encode the username and password with base64, and set it in the HTTP Authorization header.
  • Updated the structure of Kafka external stream. Mentioned RawBLOB as a supported data format.
  • Added documentation for materialized view load balancing.

Timeplus Proton v1.6.1​

  • Fixed the issue that SHOW CREATE STREAM doesn't work. Since this version, you can run either SHOW CREATE stream_name or SHOW CREATE STREAM stream_name.
  • Refined the display of datetime value in proton client. Same behavior as before, if the timezone is not specified. For datetime('UTC'), "Z" will be shown at the end. For other timezones, such as datetime('Europe/London'), the full timezone offset will be shown, such as "2024-09-10 18:21:46+01:00".

Timeplus Python Driver v0.2.11​

Sling v1.2.21 and v1.2.22​

Sling is a CLI tool that extracts data from a source storage/database and loads it in a target storage/database. You can use sling to export data from one Timeplus deployment and import to the other Timeplus deployment. In these 2 releases, we contributed a few new features and enhancements:

  • Added new SLING_DIRECT_INSERT environment variable to enable direct data inserts from source Timeplus to the target Timeplus, bypassing a temporary table.
  • By default, the exported CSV files use " to quote the value. Now this can be customized to any value, such as $a,b$, instead of "a,b".

Documentation Updates​

  • The top navigation bar is updated to provide quick accesses to the major steps to use Timeplus.
  • Refined Insert Idempotency page to highlight x-timeplus-idempotent-id is available in Ingest REST API. Also explained the max_idempotent_ids setting.

Jun 24, 2024​

Timeplus Enterprise v2 is now available for cloud or self-hosted deployment. See installation options for self-hosting.

Timeplus Enterprise v2.3.0​

Self-Hosted:

  • Account setup flow for self-hosted deployment: create account and login screens.
  • License management: In Workspace Settings, see your existing licenses and entitlements. Contact us to purchase a new license, then enter the license key and upload the license file in Workspace Settings.
  • Usage monitoring: Also in Workspace Settings, see your daily usage for ingested data and scanned external stream data.
  • Preview: Python User-Defined Functions (UDF). Create UDFs by leveraging Python libraries, such as pandas. Contact us to try this feature.

Timeplus Proton v1.5.11​

  • When creating an external stream for Apache Kafka and running select count() from table(stream), Timeplus Proton will retrieve the number of messages in the Kafka topic. If you set data_format = "RawBLOB", one_message_per_row=false, Proton will use the Kafka offset to get the message count. But if one_message_per_row=true, then Proton will read each message to split the rows. It won’t retrieve the result as fast as calculating the offset, but it will be more accurate.
  • When using an external stream to write data to Kafka, a new setting kafka_max_message_size is now available. When the external stream is created with data_format='JSONEachRow',one_message_per_row=false, each message in Kafka may contain multiple rows, with each row being a JSON document. This new setting kafka_max_message_size will control how much data will be put in a Kafka message and when to create a new Kafka message, ensuring each message won't exceed the kafka_max_message_size limit.
  • New function: array_fold, which is equivalent to the Array.reduce function in JavaScript, and is used to fold or reduce the elements in an array from left to right by applying a lambda-function to the array elements in a cumulative manner.
  • array_max/min functions now support datetime.
