What is Apache Pinot?

Pinot 1.6 adds SQL DDL and vector backends, and now needs Java 25 to run its services.

1.6.0 on 29 October lets operators manage tables through CREATE, DROP and SHOW statements, gives materialized views DDL and single-stage query rewrite, and adds GROUPING SETS, ROLLUP and CUBE to both query engines. Vector search gains IVF_FLAT, IVF_PQ and IVF_ON_DISK backends alongside HNSW. The release also removes legacy pieces: native text and FST indexes, Spark 2 and Presto integrations, and APIs deprecated through 1.3.0.

What is Fluentd?

Fluentd 1.20 drops its yajl dependency to keep building on Ruby 4.1

Fluentd shipped 1.20.0 and 1.20.1 on the same day in late October. 1.20.0 replaces yajl with Ruby's built-in JSON, adds opt-in threaded parsing and directory watching to in_tail, a command timeout for in_exec, TCP keepalive for out_forward, a umask option and a cap on evacuated buffer chunks. 1.20.1 removed yajl-ruby from runtime dependencies because it cannot build on Ruby 4.1, so plugins that require it must now declare it themselves. 1.19.4 in September fixed buffer accounting leaks, a path traversal check and syslog limits.

Pinot 1.6 adds SQL DDL and vector backends, and now needs Java 25 to run its services.

◆ Current state

1.6.0 on 29 October lets operators manage tables through CREATE, DROP and SHOW statements, gives materialized views DDL and single-stage query rewrite, and adds GROUPING SETS, ROLLUP and CUBE to both query engines. Vector search gains IVF_FLAT, IVF_PQ and IVF_ON_DISK backends alongside HNSW. The release also removes legacy pieces: native text and FST indexes, Spark 2 and Presto integrations, and APIs deprecated through 1.3.0.

◆ Where it's heading

Pinot is moving toward being operated like a SQL database. The multi-stage engine's SQL coverage has grown release by release, and table lifecycle now joins it, while vector backends pull retrieval workloads into the same store. The upgrade cost is real: Java 25 for services, Scala 2.13 for Spark artifacts, and mixed-version limits around SMART aggregation. Federation, the headline of 1.5, doesn't feature in the 1.6 highlights.

◆ Prediction

Expect materialized-view rewrite to reach the multi-stage engine, since it is single-stage only today. A security patch on 1.6 would match what followed 1.5.0.

Fluentd 1.20 drops its yajl dependency to keep building on Ruby 4.1

◆ Current state

Fluentd shipped 1.20.0 and 1.20.1 on the same day in late October. 1.20.0 replaces yajl with Ruby's built-in JSON, adds opt-in threaded parsing and directory watching to in_tail, a command timeout for in_exec, TCP keepalive for out_forward, a umask option and a cap on evacuated buffer chunks. 1.20.1 removed yajl-ruby from runtime dependencies because it cannot build on Ruby 4.1, so plugins that require it must now declare it themselves. 1.19.4 in September fixed buffer accounting leaks, a path traversal check and syslog limits.

◆ Where it's heading

The project is clearing old native dependencies ahead of new Ruby versions while making in_tail cheaper at high file counts. The hardening theme from 1.19.3 and 1.19.4 continues in the buffer and input paths.

◆ Prediction

Expect 1.20.x patches driven by plugins that break without yajl-ruby, since 1.20.1 pushes that dependency onto plugin authors.
