Amplitude vs Delta Lake: at a glance
What is Amplitude?
Amplitude shipped AI Visibility 2.0 with MCP, agentic onboarding, and a new Premium plan tier.
April's release wave is dominated by an AI Visibility 2.0 expansion (sentiment, recommendations, event data, MCP support, and a new Premium plan tier) and a Wizard CLI for agentic onboarding. Around it, Amplitude added Session Replay capabilities (page-level URL masking, replay insights, bookmarkable replays, sentiment filter), a Global Agent chat sidebar that opens by default, and AI-feedback plumbing (ingestion API, AI Assistant chats fed into feedback). The captured feed includes three near-duplicate March-31 capture variants of the same April digest, plus older monthly digests back to August.
What is Delta Lake?
Delta Lake's public stream is Databricks builds and code cleanup on the way to 4.5.
Recent Delta Lake activity is release mechanics. The newest entries are a Delta Kernel 4.5.0 Databricks build, the removal of unused V2 streaming snapshot code, and CI changes that pause idle source-build jobs now that Spark 4.0 to 4.3 use published artifacts. The last user-facing fix in the window is still 3.3.3's log cleanup correction.

Amplitude shipped AI Visibility 2.0 with MCP, agentic onboarding, and a new Premium plan tier.
◆ Current state
April's release wave is dominated by an AI Visibility 2.0 expansion (sentiment, recommendations, event data, MCP support, and a new Premium plan tier) and a Wizard CLI for agentic onboarding. Around it, Amplitude added Session Replay capabilities (page-level URL masking, replay insights, bookmarkable replays, sentiment filter), a Global Agent chat sidebar that opens by default, and AI-feedback plumbing (ingestion API, AI Assistant chats fed into feedback). The captured feed includes three near-duplicate March-31 capture variants of the same April digest, plus older monthly digests back to August.
◆ Where it's heading
The compounding theme across six months: Amplitude is becoming an agentic analytics platform — Chart Chat in September, Amplitude MCP launched in October, Dashboard Agent in February, External MCP Tools in January, Global Agent and now AI Visibility 2.0 with MCP in April. The Premium plan tier introduced with AI Visibility 2.0 is the monetization step that signals AI is being treated as a separate revenue line, not a free upgrade. Session Replay is on a parallel track maturing into a serious enterprise feature.
◆ Prediction
Watch for the Wizard CLI to evolve into a fuller programmable agentic onboarding flow — likely tied into Amplitude's CDP and customer-data layer. The Premium plan tier will likely accumulate AI-only features (advanced sentiment, agent compute), turning the AI suite into a clean upsell from the analytics base.
Delta Lake
5.0ANALYTICS
Delta Lake's public stream is Databricks builds and code cleanup on the way to 4.5.
◆ Current state
Recent Delta Lake activity is release mechanics. The newest entries are a Delta Kernel 4.5.0 Databricks build, the removal of unused V2 streaming snapshot code, and CI changes that pause idle source-build jobs now that Spark 4.0 to 4.3 use published artifacts. The last user-facing fix in the window is still 3.3.3's log cleanup correction.
◆ Where it's heading
The 4.5 line is being prepared in the open through kernel builds and cleanup, with the Spark connector consolidating V2 streaming onto the V1 snapshot path. The feed shows no 4.5 release notes yet.
◆ Prediction
A 4.5.0 release candidate or tag is the next visible step; until then expect more kernel builds and cleanup PRs.
