	Page section "lambda Architecture" page 104 figure 3-14	The figure 3-14 illustrating the lambda architecture doesn't illustrate what is described in the paragraph above it. the author says : "In a Lambda architecture (Figure 3-14), you have systems operating independently of each other—batch, streaming, and serving." In the figure we have 2 streaming systems (the batch system is not shown) and a serving system. Note from the Author or Editor: The bottom box that says "stream processing" that attaches to "batch processing" should say "batch processing".	Anonymous	Nov 15, 2022	Jul 28, 2023

Printed	Page page 241, or in the Frequency sub section middle image	Figure 7-4 shows ingestion frequencies of data in batch, micro batch, and real time. The sub headings of frequent and semi-frequent are in the wrong order. It should be batch = semi-frequent micro-batch = frequent	Joe Reis	Jul 31, 2023
	Page Page Number: 273 Section - Data Definition Language, 2nd Paragraph	On Page Number 273, within the Data Definition Language section, there it is mentioned in para2 that classifies "UPDATE" as a DDL expression. However, it should be noted that "UPDATE" is typically considered as a DML expression. Note from the Author or Editor: Thanks for spotting this error.	Divyansh Jain	Nov 16, 2023
	Page p.307 l. -3.	The line "That's it! Now let’s look at ways to view data contextually using satellites.' does not seem to fit in this place The line should be just below the table 8-18, and above the 'Satelites' paragraph. Note from the Author or Editor: This might read better if we move the "That's it! Now let’s look at ways to view data contextually using satellites.' sentence to the end of the Link section, after the sentence that says "Note that we're...". This is the sentence right before the satellite portion begins.	HIDEMOTO NAKADA	Jan 14, 2024
	Page 168 2nd paragraph	"...which we discuss at greater length in 'Messages and Streams' on page 167.)" should probably read, "...which we discuss at greater length in 'Message Queues and Event-Streaming Platforms' on page 259.)". In its current form, this is a self-referential breadcrumb, and the preceding paragraphs in the section do not "discuss at greater length," whereas the aforementioned section starting on page 259 does go into more detail. This is a particularly confusing typo due to the section name. Indeed, I did not understand the parenthetical until 100 pages later! Note from the Author or Editor: O'Reilly - can we fix this? Thanks.	Adam Shamlian	Nov 16, 2022	Jul 28, 2023
	Page 174 Bottom of page	The JSON object printed at the bottom of this page is not formatted properly for some of the nested data. It makes reading and interpreting what this data represents quite difficult. The two lines after the lines starting with "name" ("first" and "last") should have two additional leading spaces. Same for four lines after "favorite_bands". Joe Reis, co-author, sent me to this link after we discussed this on LinkedIn. I would be more than happy to volunteer to help out with helping fix formatting. Note from the Author or Editor: O'Reilly - can we better format this? Thanks.	Brian Armstrong	Dec 12, 2022	Jul 28, 2023
	Page 184 3rd page paragraph; 1st paragraph in subsection "Topics."	The last sentence of the paragraph reads, "A topic can have zero, one, or multiple producers and customers on most event-streaming platforms." It should probably read, "A topic can have zero, one, or multiple producers and consumers on most event-streaming platforms." So, "consumers", not "customers ". Note from the Author or Editor: Confirmed. Please correct.	L. D. Nicolas May	Aug 27, 2023
	Page 219 First paragraph	In the first paragraph there is a reference to a figure that reads (see Figure 6-3). It should reference Figure 6-2. Note from the Author or Editor: Confirmed	Mike Porter	Sep 03, 2023
Printed	Page 287 Not sure, got feedback from someone	Page 287 "if new events arrive for the use" should be user	Joe Reis	Feb 11, 2023	Jul 28, 2023
