ROI

Sentiment score
5.8
MarkLogic boosts ROI by enhancing efficiency, reducing complexity, and accelerating processes, saving costs and improving team focus.
Sentiment score
6.2
Organizations report cost savings and efficiency with Azure Cosmos DB, but some experience complexity and difficulty achieving expected savings.
For example, by using MarkLogic to handle semi-structured data directly, I have reduced ETL prep and transformation time by roughly 30 to 40 percent, freeing up engineers to focus on more value-added tasks instead of manual data cleaning.

Room For Improvement

MarkLogic presents a steep learning curve, outdated UI, costly infrastructure, and requires better documentation, tooling, and ecosystem support.
Microsoft Azure Cosmos DB needs improvements in query complexity, API integration, performance, documentation, cost management, and user-interface enhancements.
You do not need to worry about maintaining your own servers or provisioning your own servers. You simply log in and tell MarkLogic you want a certain number of clusters or nodes in a cluster and what cloud provider you want to use, then click okay, and they will build it for you.
Staff Engineer at a tech vendor with 10,001+ employees
There is a steep learning curve for this technology; XQuery and internal concepts such as indexing and CTS queries take time to learn compared to more common databases such as MongoDB.
Software Engineer at ValueMomentum
Cost and licensing can be a consideration, especially for smaller teams or startups compared to open-source alternatives.
Senior Software Developer at NIT
We must ensure data security remains the top priority.
Cloud Solutions Architect and Microsoft Principal Consultant for EMEA at a tech vendor with 10,001+ employees
You have to monitor the Request Units.
Co-Founder at arpa
The dashboard could include more detailed RU descriptions, IOPS, and compute metrics.

Setup Cost

MarkLogic's high pricing offers enterprise features and support, making it viable despite higher costs compared to open-source options.
Azure Cosmos DB pricing varies, appreciated for scalability but seen as costly with high demand and complex environments.
The initial setup cost is moderate to high, mainly due to infrastructure provisioning, licensing costs, and initial configuration and onboarding efforts.
SDE 2 at Virtusa
MarkLogic is quite costly, and they are looking to move away in the longer run for that reason.
Staff Engineer at a tech vendor with 10,001+ employees
MarkLogic follows a licensing model that can be relatively higher compared to open-source databases, making cost an important factor for smaller teams.
Senior Software Developer at NIT
Initially, it seemed like an expensive way to manage a NoSQL data store, but so many improvements that have been made to the platform have made it cost-effective.
Lead Cloud Architect at Solliance, Inc
Cosmos DB is expensive, and the RU-based pricing model is confusing.
IT Data Architect & Manager at Ternium Mexico S.A. de C.V.
Cosmos DB is great compared to other databases because we can reduce the cost while doing the same things.
Lead Software Architect at CPower
 

Valuable Features

MarkLogic offers advanced search, flexible data models, and high performance, enabling efficient data integration and consolidation in organizations.
Microsoft Azure Cosmos DB is valued for scalability, ease of integration, global distribution, security, and support for diverse applications.
It has a very rich search and cts APIs to build search engines on large datasets.
Staff Engineer at a tech vendor with 10,001+ employees
I personally appreciate the built-in search feature because it indexes all data immediately upon ingestion for rapid searching, so we can perform full-text, phrase, or geospatial searches.
Non IT Recruiter at a computer software company with 11-50 employees
MarkLogic provides a Google search-like capability, including full-text search, partial matching, and relevance scoring.
Software Engineer at ValueMomentum
The most valuable feature of Microsoft Azure Cosmos DB is its real-time analytics capabilities, which allow for turnaround times in milliseconds.
Vice President, Machine Learning at a healthcare company with 10,001+ employees
Performance and security are valuable features, particularly when using Cosmos DB for MongoDB emulation and NoSQL.
IT Data Architect & Manager at Ternium Mexico S.A. de C.V.

Featured Reviews

Senior Data Engineer at a insurance company with 10,001+ employees
Handling hierarchical insurance data has improved ETL workflows and still needs better integration
There are several things I have observed regarding MarkLogic's improvement areas. One challenge I notice is the learning curve and setup; it can be complex for someone new, especially when integrating with other systems or setting up indexing strategies for large datasets. I occasionally spend extra time fine-tuning indexes or query performance for really large documents. Another observation concerns tooling and ecosystem support, as it does not feel as rich as mainstream databases such as Hive or SQL servers in terms of connectors and integration or community resources. Sometimes I need to build custom scripts to bridge these gaps. Finally, monitoring and debugging distributed queries can be tricky; while it has built-in tools, deeper performance profiling or tracing is not always intuitive. Overall, these are not deal-breakers, but improvements in onboarding, ecosystem connectors, and monitoring would enhance the experience.

Senior Director of Product Management at a tech vendor with 1,001-5,000 employees
Provides super sharp latency, excellent availability, and the ability to effectively manage costs across different tenants
For integrating Microsoft Azure Cosmos DB with other Azure products or other products, there are a couple of challenges with the current system. Right now, the vectors are stored as floating-point numbers within the NoSQL document, which makes them inefficiently large. This leads to increased storage space requirements, and searching through a vast number of documents in the vector database becomes quite costly in terms of RUs. While the integration works well, the expense associated with it is relatively high. I would really like to see a reduction in costs for their vector search, as it is currently on the expensive side. The areas for improvement in Microsoft Azure Cosmos DB are vector pricing and vector indexing patterns, which are unintuitive and not well described. I would also like to see the parameters of Fleet Spaces made more powerful, as currently, it's somewhat lightweight. I believe they've made those changes intentionally to better understand the cost model. However, we would like to take a more aggressive approach in using it. One of the most frustrating aspects of Microsoft Azure Cosmos DB right now is that you can only store one vector per document. Additionally, you must specify the configuration of that vector when you create an instance of Microsoft Azure Cosmos DB. Once the database is set up, you can't change the vector configuration, which is incredibly limiting for experimentation. You want the ability to try different settings and see how they perform, as there are numerous use cases for storing more than one vector in a document. While interoperability within the vector database is acceptable—for example, I can search for vectors—I still desire a richer set of configuration options.
