Release notes

Striim Platform ships with Kafka 3.9.1. The following High CVEs (see www.cve.org) have been observed in this version of Kafka:

To mitigate these, Striim recommends downloading and running Kafka 4.x (see Using an external Kafka server).

Starting with release 5.4.2, Salesforce CDC Reader changes the metadata and the values that it generates, as follows:

As a result of these changes, the Striim type in an existing application may no longer match the data array that the reader generates. Applications with schema evolution enabled are expected to terminate after you upgrade to 5.4.2.

To resume processing, note the Replay ID of the last successfully processed event, then recreate the application and configure it to start from that Replay ID:

Starting with release 5.4.2, Salesforce CDC Reader does not support undeleted columns. Salesforce can restore a deleted custom field along with its data, but Striim does not replicate that restoration. When CDDL is enabled, dropping a column at the source hard-deletes the corresponding column at the target.

When a custom field is deleted, Salesforce appends a _del suffix to its API name, and columns with this suffix are excluded from the Striim data pipeline. Salesforce advises removing the suffix when you undelete the field. Doing so can return the column to the pipeline, but the values that were in the deleted column are not restored.

Starting with release 5.4.2, you can use the Striim wizard to create an application that combines Salesforce Reader and Salesforce CDC Reader to perform an initial load followed by continuous replication. Salesforce Reader performs the initial load using a SELECT query, and Salesforce CDC Reader performs ongoing replication by reading change events. Because the two readers retrieve data through different mechanisms, the set of columns emitted during the initial load may differ from the set emitted during CDC; use ColumnMap() at the target to align the two schemas.

Starting with release 5.4.2, the default value of ServiceNow Reader's Fetch Size property has been reduced from 10000 to 1000. Applications created in earlier releases retain their existing Fetch Size value.

Starting with release 5.4.2, for Salesforce Reader, Salesforce CDC Reader, Salesforce Writer, and Salesforce Pardot Reader, the Consumer Secret property is no longer used and no longer appears in the Flow Designer when OAuth Authorization Flows is JWT_BEARER.

Starting with release 5.4.0.2, the Oracle Reader property Read Archive Logs Only has been renamed Archive Fence.

Kafka Reader and Kafka Writer versions 0.11 and 2.1.1 are no longer supported. As part of upgrading to Striim 5.4, all Kafka Reader and Kafka Writer adapters in created or quiesced applications will be upgraded to the new versions of the adapters and corresponding connection profiles will be created. If after upgrading you need to import TQL exported from Striim 5.2 or earlier, edit the TQL before importing to use the new properties, and create a connection profile with the appropriate properties. For more information, see Upgrading from Kafka Reader 2.1 or Upgrading Existing Applications that use Kafka Writer.

Starting with release 5.4.0.2, the connection profile endpoint type BigQuery Metastore Catalog has been renamed BigLake Metastore Catalog, to reflect the name change by Google. On upgrading, BigQuery Metastore Catalog connection profiles will automatically be converted to BigLake Metastore Catalog connection profiles.

Starting with release 5.2.0, the syntax for defining external sources using the CREATE EXTERNAL SOURCE statement has been updated to simplify configuration and support additional source types. For details and updated examples, see CREATE EXTERNAL SOURCE.CREATE EXTERNAL SOURCE

The event AIData data model for Sentinel was modified in 5.0.6, with the names of two fields updated from 5.0.2. The number of unique sensitive data identifiers is now specified by numIdentifiers (formerly, Identifiers in 5.0.2), and the number of occurrences of all sensitive data identifiers is now specified by numOccurrences (formerly, Occurrences in 5.0.2).

Starting with release 5.4.0.2, Striim Platform requires JDK 17. Due to this change, once you upgrade to Striim 5.4.0.2, it will not be possible to downgrade to a previous release.

Kafka Reader and Kafka Writer versions 0.8, 0.9, and 0.10 are no longer supported. When you upgrade from Striim 4.x to Striim 5.x, any applications using those versions will automatically be updated to use Kafka Reader 2.1 or Kafka Writer 2.1 (which are backward-compatible with the old versions).

As part of upgrading from Striim 4.x to Striim 5.x, a Snowflake Writer with Streaming Upload enabled and Authentication Type set to OAuth or Password will have that property value switched to Key Pair.

Starting with release 4.2.0, TRUNCATE commands are supported by schema evolution (see Handling schema evolution). If you do not want to delete events in the target (for example, because you are writing to a data warehouse in Append Only mode), precede the writer with a CQ with the select statement SELECT * FROM <input stream name> WHERE META(x, OperationName) != 'Truncate'; (replacing <input stream name> with the name of the writer's input stream). Note that there will be no record in the target that the affected events were deleted.Handling schema evolution

OJet requires Oracle Instant Client version 21.6. See Install the Oracle Instant Client in a Striim server or Install the Oracle Instant Client in a Forwarding Agent.

MongoDB Reader no longer supports MongoDB versions prior to 3.6.

MongoDB Reader reads from MongoDB change streams rather than the oplog. Applications created in releases prior to 4.2.0 will continue to read from the oplog after upgrading to 4.2.1. To switch to change streams:

Databricks Writer's Upload Policy's default eventcount value has been increased from 10000 to 100000 and the Hostname property has been removed, since the host name can be retrieved using the connection URL. (See Databricks Writer properties.)
