OpenSearchCon India 2026 was held in person on June 15–16, 2026, at Mumbai’s Jio World Convention Centre. The event is now over, but its official schedule, speaker-provided slides and session recordings remain useful for engineers evaluating OpenSearch for search, observability, security analytics, vector search and AI applications.
What is OpenSearchCon India?
OpenSearchCon India is a Linux Foundation event for the OpenSearch community. It brings together OpenSearch users, platform and search engineers, site reliability engineers, developers, contributors, AI/ML specialists, security teams, solutions architects and technology leaders.
The focus is practical: building and operating search, analytics, observability and security applications with OpenSearch and its surrounding ecosystem. It is not a general consumer-technology conference or a replacement for a broad cloud-native event.

A 2026 Linux Foundation sponsorship prospectus called it the fourth annual OpenSearchCon India; that description should be attributed to the prospectus rather than treated as an independently documented history of every previous edition.

2026 dates, venue and format
- Dates: June 15–16, 2026
- City: Mumbai, India
- Venue: Jio World Convention Centre
- Format: In-person
- Schedule time zone: India Standard Time (IST), UTC+5:30
The official schedule is the best reference for the published program. It warned that session times and room assignments could change, so it should be read as the event directory rather than a guaranteed minute-by-minute historical record.
What was on the program?
Monday, June 15, included keynotes, technical breakouts, the Solutions Showcase and the Search Party. Tuesday, June 16, continued with keynotes, breakouts and the Solutions Showcase.
The event’s sponsorship material also described workshops, hands-on labs, round tables, an unconference and networking opportunities. Availability and access could depend on the relevant registration category, so readers planning a future edition should check its new registration and FAQ pages rather than reuse 2026 assumptions.

Technical themes
The official event material identified a broad set of subjects. The detailed schedule should be used for individual session descriptions, while the following themes explain the conference’s technical scope:
- Search and relevance: keyword, semantic, hybrid and analytics-oriented search applications.
- Vector and AI workloads: vector databases, embeddings, generative AI and retrieval-oriented systems.
- Observability: telemetry pipelines, OpenTelemetry integrations, logs, metrics and traces.
- Security: security analytics, access controls and operational security use cases.
- Search-engine foundations: Apache Lucene and the internals that affect indexing, querying and relevance.
- Production operations: scaling, capacity planning, reliability, upgrades and managed OpenSearch operations.
- Community and ecosystem: integrations, networking, collaboration and project development.
This is an official description of the event’s coverage, not a claim that every listed topic appeared in every session or that the conference announced a particular product milestone.
Who was represented?
The official “Who’s Attending” directory listed organizations spanning technology companies, enterprises, universities, media and open-source participants. Examples included AWS, Apple India, Confluent, CrowdStrike, Ericsson, Freshworks, GitLab, IBM, Microsoft, NetApp Instaclustr, Oracle Cloud Infrastructure, Stripe, Uber and Western Digital.
That directory is evidence of organizations listed by the event. It is not proof that every organization sponsored the conference, presented a session or sent a particular number of delegates.
How it fitted into the wider India event week
OpenSearchCon India shared the broader Linux Foundation and CNCF event cycle in Mumbai, but it was a separate event with its own registration rules. The co-located-events page listed this sequence:
| Event | Dates in 2026 |
|---|---|
| MCP Dev Summit Mumbai | June 14–15 |
| OpenSearchCon India | June 15–16 |
| Open Source Summit India | June 16–17 |
| KubeCon + CloudNativeCon India | June 18–19 |
All were part of the wider Mumbai venue cycle, but attending one did not automatically grant access to every conference. The Linux Foundation co-located-events page listed separate registration instructions.
What did registration cost?
The 2026 co-located-events page listed OpenSearchCon India at $49 USD or ₹4,400 INR and said pre-registration was required. It also described the option to add the event to a KubeCon + CloudNativeCon India registration.
Those figures are a historical 2026 price signal, not a standing price for a future OpenSearchCon India. The event has ended, and a future edition may use different dates, currencies, categories, discounts or registration conditions.

- Start with the official OpenSearchCon India page for the event status and post-event links.
- Use the official schedule to browse sessions and any presentation files supplied by speakers.
- Follow the event page’s link to the OpenSearch Project YouTube channel for session recordings.
Not every session necessarily has a recording or slides. The event page says slides are available when speakers provided them, so the schedule remains the authoritative place to check individual sessions.
Who should follow the content?
- Developers: teams building keyword, semantic, hybrid or vector search, AI retrieval systems, search-backed applications or OpenSearch integrations.
- Platform and SRE teams: engineers responsible for clusters, indexing and query performance, telemetry, capacity, security and recovery.
- Data and AI teams: practitioners working with embeddings, semantic search, RAG-style applications and large-scale analytics.
- Engineering leaders and procurement teams: buyers comparing self-managed OpenSearch with managed services and assessing portability, operational effort and cloud dependence.
The material is less relevant if you are looking for a general cloud-computing expo, a consumer-tech show or a vendor-neutral introduction with no OpenSearch deployment interest. Remote readers can still obtain substantial value from recordings, slides and the archived schedule.

Conference content can inform a deployment decision, but attendance or sponsorship does not establish that one vendor is better than another. Compare the operating model as carefully as the search features.
| Option | Potential fit | Important trade-offs |
|---|---|---|
| Self-managed OpenSearch | Organizations needing maximum control, customisation or specific data-residency arrangements. | You own infrastructure, upgrades, backups, monitoring, scaling, security and incident response. It is not automatically cheaper once specialist operations are included. |
| Amazon OpenSearch Service | Teams already standardised on AWS and its logging, security and analytics services. | Managed clusters are billed through instance hours, storage and data transfer; Serverless uses OpenSearch Compute Units and storage. Region, retention and workload behaviour materially affect cost. See the official pricing page. |
| Aiven for OpenSearch | Teams seeking a managed service with multi-cloud options and consolidated operations. | Aiven’s displayed plans varied by cloud and region. On August 16, 2026, its pricing page showed tiers from a free option and $40/month Developer tier to higher plans starting at $90, $275 and $1,140 per month. Treat these as dated starting signals, not universal quotes. |
| Bonsai | Product teams wanting a specialised managed search provider. | Displayed plans ranged from low-cost staging and standard tiers to business and enterprise offerings. Normalize storage, memory, document limits, availability, backups, support and region before comparing headline prices. |
For any provider, ask:
- Which cloud and regions are available?
- Who handles upgrades, backups, monitoring, scaling and recovery?
- Are vector, semantic, hybrid search, alerting and observability features included?
- What are the SLA, multi-zone, failover, security and private-networking options?
- Are ingestion, egress, cross-zone, backup-transfer or support charges separate?
- Can the workload move to another cloud or back to self-managed OpenSearch?
What to check before the next edition

Bottom line
OpenSearchCon India 2026 was a completed, two-day Mumbai conference focused on practical OpenSearch work across search, observability, security, AI and operations. If you missed it, the most useful next step is to open the official schedule, follow its available presentation links and use the event page’s route to the OpenSearch Project YouTube recordings. For a production decision, treat the conference as technical context—not as a substitute for workload testing, security review and a careful comparison of self-managed and managed-service costs.
